They were yellow because if they went down on a training mission—as they often did—they were easier to spot from the air.

Often the trainees made unscheduled off-airport landings in hayfields, swamps, forests, and the desert. Having an aircraft painted to look like terrain would have made it more difficult to find them.

Answer: The LSA rule as it stands limits aircraft to a gross weight of 1,320 pounds for land aircraft.

• READ MORE: Pilots Have Questions When It Comes to MOSAIC

Gross weight is determined when the aircraft is certificated. The Cessna 140 GW is 1,450 pounds, and the Cessna 150 is between 1,500 and 1,600 pounds, depending on the year of manufacture. You can take the other seat out and fly partial fuel, and that will make the aircraft lighter, but it won’t change the certificated gross weight.

Understand that the LSA rule is under review with MOSAIC, and if approved as written, will increase the gross weight of aircraft to 3,600 pounds.

When that transpires, many of the single-engine light trainers flown today in the utility and normal category will likely become LSA compliant.

Answer: There are many observed cases of lightning strikes to aircraft inside or near clouds that had not previously produced natural lightning. Studies show that about 90 percent of the lightning strikes to aircraft are thought to be initiated by the presence of the aircraft itself. The scary statistic, however, is that 40 percent of all discharges involving airborne aircraft occurred in areas where no thunderstorms were reported.

Apollo 12

One of the more famous cases of aircraft-initiated lightning is the Apollo 12 launch at the Kennedy Space Center, Florida, in November 1969. The Saturn V rocket was struck not once but twice on its way into orbit.

According to the 1970 NASA findings, other than these two strikes, there was no other lightning activity reported six hours before or six hours after the launch. At the time of the launch, a cold front was moving south into the launch area. Broken towering cumulus topping out at 23,000 feet with light to moderate rain showers were reported.

Rarely Fatal

Damage to airborne aircraft struck by lightning includes minor pitting or scarring to the aircraft’s skin to complete destruction of the aircraft.

Besides direct damage at the point of entry and/or exit, indirect effects that include the loss of VHF communication, loss of navigation equipment, and loss of instrument panel gauges are also possible.

In 1963, a Pan American Airlines Boeing 707 over Elkton, Maryland, was struck by lightning while in a holding pattern at 5,000 feet. The outermost fuel tank in the left wing exploded causing two other fuel tanks to follow suit. There were no survivors.  

• READ MORE: Does the FAA Punish Pilots for Logbook Mistakes?

It’s certainly true that a catastrophic accident such as this is extremely rare, but lightning strikes to aircraft are more common than you might imagine—most of which are aircraft-initiated strikes.

Based on compiled data it is estimated that in the U.S. a commercial airliner is struck once for every 3,000 hours flown. That’s an equivalent of about one strike each year. 

Melting Level

While aircraft-initiated lightning is still being actively studied, there are a few important characteristics to consider.

Based on the current research, it doesn’t take flying in or near a mature thunderstorm to become the victim of a lightning strike. The mere presence of the aircraft in an environment conducive to an electrical discharge is all that is necessary.

Most of the aircraft-initiated lightning strikes occur when the aircraft is flying at or near the melting level (0 degrees Celsius). The preferred temperatures include a range from plus-3 C to minus-5 C, with the highest number of incidents occurring right at the melting level.  

A few of the strikes down low are the result of an aircraft intercepting a lightning strike in progress. Essentially, this is the case of being in the wrong place at the wrong time.

On the other hand, aircraft-initiated strikes are observed the most are between 3 km and 5 km or 10,000 to 16,000 feet during the warm season. Once again, temperature is a key factor. The melting level that typically occurs is in this same range of altitudes throughout the summer months.  

Low-Topped Convection

In general, natural lightning in deep, moist convection doesn’t form until the tops of the storm build well above the melting level.

For lightning to form, three ingredients must be simultaneously present. These include vapor-born ice crystals, graupel, and supercooled liquid water. If any one of these three is missing in sufficient quantities, natural lightning doesn’t generally occur, but this not to say the cloud is void of all electrical activity—some still remains.    

Therefore, an aircraft-initiated lightning strike typically occurs within local air mass instability within low-topped convection.

Often low-topped convection doesn’t produce natural lightning. The updrafts are rather weak in comparison to those that do produce lightning. Consequently, the updrafts do not carry enough supercooled liquid water into the upper part of the cloud where it is needed. 

• READ MORE: What Are Echo Tops?

Clouds and Precipitation

An overwhelming number of lightning strikes occur within the cloud itself. Only a very small percentage of strikes occur outside of the cloud boundary or below the cloud.

Here’s the key: A very large percentage of the strikes occur within precipitation to include rain, snow, snow grains, ice pellets, and hail. It is not uncommon to find a mixture of these near the melting level. 

Keep Your Distance?

The FAA encourages all pilots to keep a safe distance from an active thunderstorm for obvious reasons.

Unfortunately, this practice alone isn’t quite enough. Even when thunderstorms (natural lightning) are not occurring or expected to occur, an aircraft-initiated lightning strike can still be a risk.

In order to avoid an encounter with lightning, the best advice is to remain in cloud-free air whenever possible, especially when the atmosphere is conditionally unstable and capable of producing marginally deep, moist convection extending well above the melting level.

While it may be difficult, the best advice is to operate outside of areas of precipitation and minimize your time in clouds and precipitation near the melting level.

Answer: The short answer is no. But unfortunately there’s a lot of “tribal knowledge” surrounding logbooks and what can happen. FLYING contacted the FAA for the correct information.

Endorsements

The CFI should be familiar with Advisory Circular 61-65 (H), which contains the endorsements an instructor is allowed to give. The language is copied verbatim. If you are a learner pilot, the first endorsement you will get is the TSA citizenship verification endorsement in accordance with 49 CFR 1552.3(h).

FAR 61.51 covers pilot logbooks and details how to log “training time and aeronautical experience.” It states that each person must document and record the following time in a manner acceptable to the administrator:

(1) Training and  aeronautical experience used to meet the requirements for a certificate, rating, or flight review of this part.

(2) The aeronautical experience required for meeting the recent flight experience requirements of this part.

Part B covers logbook entries, stating that “for the purposes of meeting the requirements of paragraph (a) of this section, each person must enter the following information for each flight or lesson logged:

(1) General—

(i) Date.

(ii) Total flight time or lesson time.

(iii) Location where the aircraft departed and arrived, or for lessons in a full flight simulator or flight training device, the location where the lesson occurred.

(iv) Type and identification of aircraft, full flight simulator, flight training device, or aviation training device, as appropriate.”

The savvy CFI logs all instruction given, including ground time and the topics covered. If the learner takes the time to be there, they should get credit for the experience.

As far as “messing up an entry in a logbook,” FLYING posed a series of questions gleaned from scenarios encountered in more than 30 years of flight training on both sides of the CFI certificate.

Ink Color

I start with this because when I was working on my CFII certificate, I logged time in my own logbook with blue ink and the CFII who I was training with positively clutched her pearls over that one.

According to the FAA, they do not require a specific ink color for a paper logbook.

The logging of time spent using an advanced aviation training device (AATD) can be controversial as there are some CFIs who refuse to do it, saying it will “ruin” a logbook.

According to the FAA: “Simply logging time (in any capacity) does not ruin a logbook, but the pilot must ensure they are properly categorizing the flight time logged. For example, if a pilot decided to record their time spent using an AATD in their logbook, that is acceptable. However, the AATD time could not be counted toward cross-country time for pilot certification.”

Set Up Your Own Logbook

As most logbooks have a few blank columns, it’s a good idea to designate them to suit your needs. For example, you might have one for ground training received or given, AATD, solo flight, etc. You can have an entire section set aside for ground instruction, dual instruction given, etc.

Endorsements

There are many logbooks with preprinted endorsements, but you may run out of room. The FAA does not require endorsements to be on a specific page or in a specific location in the logbook. 

“Endorsements can be made in a pilot’s logbook or other documents acceptable to the administrator if the learner uses an electronic logbook rather than paper, in order to show they meet the aeronautical experience requirements for the certificate or rating that may be in paper form or electronic,” FAA said. “Keep in mind that many endorsements require a CFI’s signature which may not work with an electronic logbook.” 

For check rides most learners print out spreadsheets of their experience and have the CFI sign those.

Mistakes

Mistakes do happen. Usually they are math errors.

Filling out a logbook takes a fair amount of concentration, as does totaling up the columns and double checking the math before you sign the page. Take care when you do this, and please be extra careful when it comes to totaling up required experience for a check ride. You do not want a learner to go for a check ride and be turned away because they are missing 0.2 of something, or a takeoff and night landing or two. 

If you make a mistake, correct it. Please note that the FAA does not have specific guidance on correcting logbook errors. According to the source at the FAA, “choosing a particular correction style (white-out, crossing out the error and correcting, crossing out the line and making a new entry, etc.) is up to the pilot.”

Answer: In the scenario you described and since ATC asked you to do the maneuver in the pattern, it’s not unexpected.

• READ MORE: What Are Echo Tops?

S-turns and 360-degree turns are methods of creating space between aircraft. This keeps you from overtaking another, most likely slower, aircraft. It’s similar to the way bands march in place for a few minutes during parades to create more space between them and the parade floats, horses, or other bands ahead of them. At a towered airport, if the controller tells you to do this, they are trying to create space between you and the aircraft you are following.

While in the pattern, listen carefully for what kind of aircraft you are sharing space with. If you are flying a Cessna 182 or a twin and there is a slower aircraft like a Cessna Skycatcher or Piper Cub ahead of you, you’re probably going to need to slow down.

• READ MORE: What to Do When You Lose Your Logbook

At all times it is up to the pilot in command (PIC) to determine if it is safe to do these maneuvers If ATC asks you to do a 360-degree turn and there is an aircraft in the way, don’t do it and advise “unable.” At a nontowered airport, 360-degree turns in the pattern are a little dicey. A better option is to depart the pattern and reenter on the 45.

The post When Is It OK to Perform Unexpected Maneuvers in the Pattern? appeared first on FLYING Magazine.

Answer: The short answer is no. Echo top height is a volume product that originates from the NWS WSR-88D NEXRAD Doppler radars.

This is the same network of radars that is used to build the familiar radar mosaic pilots readily use in the cockpit. While not provided in the FIS-B broadcast, the echo top height product, however, is arguably the most misused data that is broadcast by SiriusXM to your satellite-based weather receiver.

Despite what many pilots are taught, this product does not represent the height of the cloud tops and should never be used as such since it is often likely to produce unreliable and inconsistent results.

When looking at any ground-based radar depiction, the colors you see are mapped to a quantity in decibels of Z, often abbreviated dBZ, where Z is the reflectivity parameter. As the name implies, reflectivity is the amount of energy that is returned (reflected) back to the receiver after hitting a target.

For precipitation, these targets are called hydrometeors that include rain, snow, ice pellets, and hail. There are a few exceptions, but generally speaking, the higher the dBZ value, the heavier the precipitation.

All deep, moist convection or thunderstorms have both a cloud top (the highest point of the cloud as measured from sea level) and top of the precipitation core within the convection. The “top” of the precipitation core is defined as the msl height of the highest radar reflectivity of 18 dBZ. This altitude is referred to as the echo top height.   

For example, imagine taking a vertical “slice” through a typical thunderstorm, such as the one shown above. The white dashed line shows the west-to-east slice with the echo top height shown on the left and the base reflectivity from the lowest elevation angle shown on the right. The radar depiction on the right is the view most familiar to a pilot.

However, to better illustrate how the echo tops are determined, the depiction below is this same slice from above that is shown as a vertical cross section of the radar reflectivity. In other words, it depicts all possible elevation angles from the radar’s volume scan through this slice.

The colors are the reflectivity values in dBZ. The highest values shown in the precipitation core are about 55-60 dBZ and are all below about 7 kilometers (about 23,000 feet). As height increases in the core, notice the values drop off to less than 15 dBZ.

By connecting the points where the values in the core drop off to the 18 dBZ value, this represents the echo top height (shown by the white squiggly line). For this cell, the highest point in this cross-section is 17 kilometers or roughly 56,000 feet msl.

Cloud top height, on the other hand, is higher than the echo top height. In fact, it can be 5,000 to 10,000 feet higher in some of the most intense storms.

The visible satellite image below is a good example of thunderstorms with overshooting tops. Given the time of day, the highest tops actually cast a shadow on the thunderstorm anvil. This is the column of air in the thunderstorm that will usually have the highest echo tops due to the vigorous updraft. 

Echo top heights are specifically used by forecasters to identify the most significant storms by locating the highest echo regions. Stronger updrafts are seen in regions where the highest echo tops are located.

Moreover, the parameter that has the highest apparent correlation with lightning is not the highest cloud top but rather the highest detected radar echo top of 30 dBZ or greater.

Shown above is the SiriusXM composite radar mosaic shown with the Garmin Pilot app. In addition to the radar reflectivity, storm cell identification tracking (SCIT) markers are shown.

These attempt to identify the movement and echo top height of various cells in the radar mosaic. The height provided is measured in hundreds of feet. If there’s an arrow, this defines the direction of movement, and the end of the arrow represents where the cell might be located in the next 60 minutes given its current speed and direction of movement.  

Lastly, this may seem obvious, but echo tops are not going to help identify the vertical extent of many weather systems unless those clouds are producing some kind of precipitation in the form of rain, snow, hail, or ice pellets.

Therefore, a stratus deck, even one that has some depth, won’t likely be picked up by the radar. In fact, it’s not likely you will see echo tops shown below 20,000 feet because of this. Echo tops are more appropriate for convective precipitation where the clouds have significant vertical depth.

Answer: You’re in luck. The paper student pilot certificate was issued by the aviation medical examiner (AME) and not done through IACRA as we know it, so it is doubtful the learner already has an IACRA account.

• READ MORE: Is There an Official Weather Briefing

All you have to do is sit down with the learner and create a new application. Simply follow the prompts and fill out the application. In a few weeks he will get a plastic student pilot certificate in the mail.

Also, don’t forget to also verify the learner’s citizenship and give him a TSA endorsement, which have become requirements since 2002.

Answer: According to an FAA spokesperson:  “Generally speaking, the FAA will accept [a pilot’s] last airman certificate application (Form 8710-1) or what they reported on their last medical application (Form 8500-8).” You should have access to at least one of those documents.

Pro tip: Moving forward, you may want to invest in an electronic logbook and save the information to the cloud, or at least record a digital image of each page of the paper logbook when you fill it up. If you rent aircraft, sometimes you can re-create your experience by cross-referencing your receipts.

Answer: Rudder controls the side-to-side motion of the nose of the airplane—the technical term for this is yaw.

To make the airplane turn (bank), the pilot moves the yoke or stick in the direction they want to turn. This activates the ailerons, which are the outboard, moveable panels on the wings.

The downward-deflected panel is on the outside of the turn, and as the downward deflection increases the surface area of the wing, it generates more lift. The aircraft nose yaws toward the side with the wing generating more lift. From the pilot’s perspective, that yaw is in the opposite direction of the turn. As this turn is opposite to the direction of the turn the pilot wants, the technical term for this is adverse yaw. 

In the airplane, banking without using the rudders feels a little bit like someone pulling you sideways by the seat of your pants. It is poor airmanship as it results in an uncoordinated turn.

In an aircraft with a turn coordinator or slip skid indicator (the instrument that has a tube and ball in it that acts in response to lateral motion), note that if the airplane is banked only with aileron, the ball will be to the outside of the turn. To correct this, the pilot steps on the rudder on the same side the ball is deflecting to. This corrects the adverse yaw.  “Step on the ball” is the phrase you often hear. When flying an aircraft with a glass panel that has a triangle with a lateral moving base, the phrase “step on the line” is used.

The rudder controls the adverse yaw, and when correctly applied results in a coordinated (smoother) turn.

For more information refer to the Pilot’s Handbook of Aeronautical Knowledge (available on the FAA website or at brick-and-mortar stores) in Chapter 6, Flight Controls.

Answer: It depends on your mission and how many Ben Franklins you have to spare. Your sferics (short for radio atmospherics) equipment may represent the only real-time weather you’ll ever see in your cockpit.

Sure, panel-mounted and portable weather systems deliver their product in a timely fashion, but it will never be as immediate as your sferics device. Once you understand how to interpret your real-time lightning guidance, it can become a valuable asset in your in-flight aviation toolkit. 

Choices in the Cockpit

You have two options if you want lightning data in the cockpit: You can choose from ground-based lightning sensors or onboard lightning detection from a sferics device such as a Stormscope.

A Stormscope provides real-time data but does require some basic interpretation. Ground-based lightning, on the other hand, is a bit delayed and is only available through a data link broadcast at this time. Ground-based lightning is normally coupled with other weather guidance, such as ground-based weather radar (NEXRAD), surface observations, pilot weather reports, and other forecasts.   

Ground-Based Lightning

The ground-based lightning that’s now available through the Flight Information System-Broadcast (FIS-B) comes from the National Lightning Detection Network (NLDN). This network of lightning detectors has a margin of error of 150 meters for locating a cloud-to-ground strike. The ground-based lightning sensors instantly detect the electromagnetic signals given off when lightning strikes the earth’s surface.    

With 150-meter accuracy, I’d choose ground-based lightning any day. Don’t get too excited, though. Ground-based lightning is expensive (the data is owned by private companies like Vaisala), and you’ll not likely see a high-resolution product in your cockpit anytime soon.

SiriusXM satellite weather pulls from a different lightning detection network and includes both cloud-to-ground and intracloud lightning. It produces a 0.5 nm horizontal resolution lightning product. This means that you will see a lightning bolt or other symbol arranged on your display in a 0.5 nm grid.

Even if 50 strikes were detected minutes apart near a grid point, only one symbol will be displayed for that grid point. Same is true for the FIS-B lightning.

Stormscope Advantages

A Stormscope must be viewed as a gross vectoring aid. You cannot expect to use it like onboard radar.

Nevertheless, it does alert you to thunderstorm activity and will provide you with the ability to see the truly ugly parts of a thunderstorm.  Where there’s lightning, you can also guarantee moderate or greater turbulence.   

No lightning detection equipment shows every strike, but the Stormscope will show most cloud-to-ground and intracloud strikes. This allows you to see the intensity and concentration of the strikes within a cell or line of cells with a refresh rate of two seconds. It also lets you see intracloud electrical activity that may be present in towering cumulus clouds even when no rain may be falling.

Even if no cloud-to-ground strikes are present, intracloud strikes may be present. The Stormscope can detect any strike that has some vertical component (most strikes do). This is important since there are typically more intracloud strikes than cloud-to-ground strikes.

To emphasize this point, most of the storms in the Central Plains have 10 times more intracloud strikes than cloud-to-ground strikes. Moreover, during the initial development of a thunderstorm, and in some severe storms, intracloud lightning may dominate the spectrum. 

Also keep in mind that a sferics device does not suffer from attenuation like onboard radar. That is, it can “see” the storm behind the storm to paint cells in the distance out to 200 nm, but it does not see precipitation or clouds.     

Stormscope Disadvantages

It doesn’t take a full-fledged storm, complete with lightning, to get your attention.

Intense precipitation alone is a good indicator of a strong updraft (or downdraft) and the potential for moderate to severe turbulence in the cloud. Consequently, the Stormscope does not tell you anything about the presence or intensity of precipitation or the absence of turbulence.

Never use the Stormscope as a tactical device to penetrate a line of thunderstorm cells. Visible gaps in the cells depicted on the Stormscope may fill in rapidly. Fly high and always stay visual and you will normally stay out of any serious turbulence.        

A Stormscope display is often difficult to interpret by a novice. Radial spread, splattering, buried cables, and seemingly random “clear air” strikes can create a challenge for the pilot. It may take a couple years of experience to be completely comfortable interpreting the Stormscope display. Often what you see out of your window will confirm what you see on your display.    

Radial Spread

As the name suggests, the biggest Stormscope error is the distance calculation along the radial from the aircraft.

The placement of the strike azimuthally is pretty accurate. However, how far to place the strike from the aircraft along the detected radial is a bit more complicated and prone to error.

Lightning strikes are not all made equally. When the sferics devices were invented back in the mid-1970s, they measured the distance of the cloud-to-ground strike based on the strength of the signal (amperage) generated by the strike. An average strike signature of 19,000 amperes is used to determine the approximate distance of the strike.

Statistically, 98 percent of the return strokes have a peak current between 7,000 and 28,000 amperes. That creates the potential for error in the distance calculation. This error is a useful approximation, however, in that strokes of stronger intensity appear closer and strokes of weaker intensity appear farther away. 

In strike mode on the Stormscope, strikes are displayed based on a specific strike signature, whereas cell mode on the newer Stormscope models uses a clustering algorithm that attempts to organize these strikes around a single location or cell.

Cell mode will even remove strikes that are not part of a mature cell. Most thunderstorm outbreaks are a result of a line of storms. Cell mode provides a more accurate representation to the extent of the line of thunderstorms.

Radial spread is not necessarily always a bad thing. You can use it to your advantage to distinguish between false or clear air strikes and a real thunderstorm. Most of the strikes of a real storm will be of the typical strike signature and be placed appropriately.

As mentioned above, stronger than average strikes will be painted closer to the airplane. Looking at this in strike mode, a line of these stronger strikes will protrude toward the aircraft.  The result is a stingray-looking appearance to the strikes.    

You can confirm this by clearing the display.  The same stingray pattern should reappear with the tail protruding once again toward the airplane.

Clear Frequently

Clearing the Stormscope display frequently is a must.  How quickly the display “snaps back” will provide you with an indication of the intensity of the storm or line of storms.

You should be sure to give these storms an extra-wide berth.  Clearing the Stormscope in “clear air” will also remove any false strikes that may be displayed allowing you to focus on real cells that may be building in the distance.

Aging

Both ground-based and onboard lightning use a specific symbol to indicate the age of the data.

For Stormscope data shown on the Garmin 430/530, a lightning symbol is displayed for the most recent strikes (first six seconds the symbol is bolded). The symbol changes to a large plus  sign after one minute followed by a small plus  sign for strikes that are at least two minutes old. Finally, it is removed from the display after the strike is three minutes old.

Cells with lots of recent strikes will often contain the most severe updrafts and may not have much of a ground-based radar signature. Cells with lots of older strikes signify steady-state rainfall reaching the surface that may include significant downdrafts. 

Flight Strategy

A nice feature of a Stormscope is that you can quickly assess the convective picture out to 200 nm while still safely on the ground. Same is true for lightning received from the SiriusXM datalink broadcast.

However, for those with lightning from FIS-B, you won’t receive a broadcast until you are well above traffic pattern altitude unless your departure airport has an ADS-B tower on the field.  

As soon as your Stormscope is turned on, within a few minutes you’ll get a pretty good picture of the challenging weather ahead. If you are flying IFR, you may want to negotiate your clearance or initial headings with ATC to steer clear of the areas you are painting on your display. I’ve canceled or delayed a few flights based strictly on the initial Stormscope picture while I was still on the ramp. 

Another goal is to fly as high as allowable. You will benefit from being able to get above the haze layer, and the higher altitude will allow you to see the larger buildups and towering cumulus from a greater distance.

If you are flying IFR and you are continually asking for more than 30 degrees of heading change to get around small cells or significant buildups, then you should call it quits. You are too close, or you are making decisions too late.

Visual or not, the goal is to keep the strikes (in cell mode) out of the 25-mile-range ring on your Stormscope. If one or two strikes pop into this area, don’t worry. Just keep most of the strikes outside of this 25-mile ring.      

Don’t discount the value of a sferics device.  Add one of the data link cockpit weather solutions as a compliment, and you will have a great set of tools to steer clear of convective weather all year long.
