It is not uncommon for air traffic control to pose this question to pilots on IFR flight plans approaching certain airports when the weather is VFR. In daylight, when the visibility is good, the winds calm, and the pilot familiar with the airport—and the approach is a straight in—the visual is no big deal.

But throw in weather, fatigue, low light, pilot unfamiliarity, and a circle to land, and it’s a different event.

Honeywell Aerospace is trying to mitigate these risks, expanding its navigation database to offer flight management system (FMS) guided visual procedures as a stand-alone option.

According to Jim Johnson, senior manager of flight technical services at Honeywell, the visual approaches are created in collaboration with Jeppesen. The instructions for the guided visuals look like Jeppesen approach plates but carry the caveat “advisory guidance only” and “visual approach only.” In addition, the symbology on the approaches differs in a handful of ways.

“The FMS-guided visual provides a lateral and vertical path from a fix fairly close to the airport all the way down to the runway,” says Johnson. “You can hand fly them or couple them to the autopilot.”

Visual into KTEB

One of the first guided visual approaches was created for the descent to Runway 1 at Teterboro Airport (KTEB) in New Jersey.

The airport sits in a very industrialized area with the runway blending into warehouses and business parks. Honeywell provides a video of the visual approach on its website that illustrates the value of having that helping hand. Having the extra vertical and lateral guidance from a mathematically created visual procedure allows pilots to better manage their approach, configuring the aircraft in an expedient manner to avoid “coming in high and hot” in an improperly configured aircraft.

This is quite helpful when the aircraft needs to circle to land, says Carey Miller, pilot and senior manager of technical sales at Honeywell.

“Going into Runway 1 at Teterboro on the visual, you are not aligned with the VASI,” Miller says. “There is no vertical guidance, which can lead to a dive to the runway. Add a moonless night or gusty winds, and it can be quite challenging. Not being able to see the airport is a detriment to your energy management. The visual approaches, when coupled to the autopilot, eliminate the guesswork and the overbanking tendency that can lead to stalls.”

Adds Johnson: “The aircraft will fly constant radius turns, [and] you will be on the same ground track every time because the computer knows how to manage the vertical and lateral path. It gets rid of the pilot drifting down or turning early because of the winds.”

Airspace Guidance

The guided visual procedures created thus far have come from suggestions from Honeywell customers, including a visual approach to Chicago Executive/Prospect Heights Airport in Wheeling, Illinois (KPWK). KPWK is in Class D airspace, 8 nm from Chicago O’Hare International Airport (KORD). The Class B airspace for KORD sits above KPWK. There is a V-shaped cutout with various altitudes over KPWK.

The guided visual can help the pilot avoid clipping the Class B airspace during the circle to land—and the dreaded phone call with ATC that results.

The Creative Process

Each approach is created using software tools that take into account the airspace and terrain at the airport, then test flown in simulators to check for flyability.

According to Johnson, the suggestions for where to offer the guided visual approaches come from their customers.

“There are a lot of secondary and regional airports in the U.S. that have both terrain and airspace considerations that make visual approaches very challenging,” says Johnson. “For example, Van Nuys, California [KVNY], has both airspace challenges and a ridge nearby.”

In some cases, the team may opt to create a visual approach as an overlay to improve safety at airports where closely spaced simultaneous approaches are in use. As this issue was going to press, Honeywell was working on an approach to Runway 28R/L at San Francisco International Airport (KSFO). The visual approach has a briefing sheet with textual guidance, and Honeywell has literally drawn a picture of it.

During development each procedure is flown in a simulator, using a specific briefing sheet that is checked and double-checked for accuracy and usability. Each approach has the ability to be coupled with the autopilot.

Miller cautions it is important to recognize that the visual procedures are not considered instrument approaches in the traditional sense.

“Do not request it as an approach, because ATC will not be aware of it,” Miller says. This information is emphasized on the procedure briefing sheet that accompanies each guided visual approach.

The guided visual approach is loaded in the FMS just like an instrument approach. The pilots can access them with a few pushes of a button, just as they do Jeppesen approaches.

“To use the visual approaches, the customer needs to have a Honeywell-equipped aircraft, and in addition to the FMS database, for an additional $2,000 per year they receive the visual approaches,” says Miller.

To request an approach, contact Honeywell at FTS@honeywell.com. It takes approximately four weeks to put one together.

Coming Full Circle

In many ways, the visual approach procedures represent a modern treatment to the first approaches created by Elrey Jeppesen—yes, that Jeppesen—who became a pilot in 1925 at the age of 18. At the time, there was no such thing as maps purpose-built for aviation. Pilots relied on road maps—which often weren’t terribly accurate, following railroad tracks from town to town or by pilotage and dead reckoning.

In 1925, Jeppesen went to work as a survey pilot and by 1930 was working for Boeing Air Transport, the precursor to United Airlines. This was decades before air traffic control and electronic navigation systems were created. Jeppesen bought a small notebook and filled it with information about the routes he flew. In it there were drawings of runways and airports and information that pilots needed to know, like the elevation of water towers, telephone numbers of farmers who would provide weather reports, and dimensions of the runway and its distance from the nearest city.

In 1934, this evolved into the Jeppesen Company and the notebook into the en route charts and terminal area procedures we know today. Much of Jeppesen’s flying was done in the Pacific Northwest. The Museum of Flight in Seattle is the keeper of the Elrey B. Jeppesen Collection, and for many years there was a replica of his first notebook on display in the Red Barn.

We think Captain Jepp would appreciate how far the approaches he inspired have come.

The good news is that there is a lot to do on Mackinac during the summer. And while there is far less going on during the offseason months, the place becomes a true escape from the daily grind. A handful of hotels and one or two restaurants stay open year-round, and whenever you choose to visit, general aviation is the best way to get there. With our suggestions, you can make your plans for the coming season.

Getting There

I usually make destination flights like this one in Annie, my Commander 114B, but it’s more than 500 nm from my home base at Sussex Airport (KFWN) in northern New Jersey to Mackinac Island Airport (KMCD). Because poor weather on the island and along the route had kept me from flying there earlier, I started looking for a professional pilot familiar with the area to take me there.

A friend recommended Nick Sanderson of Hangar9 Aviation, a Part 135 charter operation based at Padgham Field (K35D) in Allegan, Michigan. Sanderson and his partner, Colin West, have flown passengers to Mackinac many times in their Cessna 414A, so we booked passage with them. Like many vacation trips that involve ferries, travelers typically have to set aside a day at the beginning and end for travel. Even though the ferry ride is fairly short, the island’s remote location near the northern tip of Michigan’s Lower Peninsula and the southern tip of the Upper Peninsula means a long drive to the boat for most people. Those who live a state or two away are ideal candidates for GA, which speeds the trip along considerably.

Driving from Chicago to the island takes about seven hours or more, depending on ferry schedules. Flying there from Chicago Executive Airport (KPWK) would take less than two hours in Annie or less than 90 minutes in the 414A. Part of the driving time is the result of having to get around Lake Michigan in a car or across it in another ferry—but with proper planning you can safely cross the lake easily in a light GA aircraft.

The Airport

Pilots and passengers will enjoy a dramatic approach over Lake Huron to Runway 8/26 at KMCD, but you will not be over water for long, though, because the island’s airport lies just a few miles offshore. You can spot other airports nearby even as you fly the traffic pattern, including Bois Blanc Island (6Y1) 8.1 nm southeast, Mackinac County (83D) 5 nm west northwest, and Cheboygan County 14 nm south.

Views from the air are stunning, especially for September through October, as the foliage is changing colors. The island’s winter semi-hibernation seems to wait until the end of this natural show, which typically forms its last big attraction of the season.

The field is nontowered, with a 3,501-foot runway that is 75 feet wide—same as my home airport. This is not a big challenge, though breezy conditions will generally guarantee that it will not be the easiest landing you make this year. West was flying into a headwind of about 15 knots and probably could have made it with a runway less than half as long. The 414 coasted gently to a turnoff about two-thirds down the strip. A Beechcraft King Air arrived a few minutes after us, but most visitors that day arrived in piston singles. Jets with good short-field performance occasionally stop by, airport staff told us, but we did not see any during our stay. The airport averages 30 operations per day.

Thing to Do

The island is tiny, covering 3.8 square miles, but offers plenty of sights and activities. The downtown area is packed with hotels, restaurants, gift shops and purveyors of fudge, a signature island product. There are also a lot of horse-drawn carriages on the streets, but no cars. They are not allowed. Indeed, M-185, the 8.2-mile road around the island’s perimeter, is said to be the only state highway in the U.S. that forbids motor vehicles. There are, however, 600 horses on the island during peak season, mostly for pulling carriages. Much of the island is covered by Mackinac Island State Park, which means there is a lot of quiet, uncrowded space available, including more than 70 miles of trails in the park that take visitors past caves, rock formations, and cemeteries dating back 200 years.

People like to recite impressive numbers when talking about the island, from the 500 year-round residents, 1,489 bicycles for rent, and 24 restaurants with outdoor seating to the famous Grand Hotel’s 660-foot front porch, which they say is the longest in the world. There are also between 120 and 140 geocaches hidden on the island for modern sleuths to find.

History

The island was a sacred place for Indigenous peoples long before European colonists arrived, particularly for the Anishinaabek (Odawa, Ojibway, and Potawatomi). Mackinac became a bone of contention between U.S. and British forces during the War of 1812, when British, Canadian, and Native American soldiers captured Fort Mackinac from the small garrison based there. The taking of Mackinac was among the first engagements of the war and began more than two years of fighting between the U.S. and Britain for control of Michigan and the Great Lakes. Both sides sought control of the Great Lakes fur trade, and the conflict came to a head in 1814 when seven U.S. warships and about 1,000 soldiers arrived on a mission to recapture the island. They clashed with British forces on August 4, in a battle that the U.S. lost. It took the Treaty of Ghent to return peace to Mackinac, with U.S. soldiers taking possession of Fort Mackinac in July 1815.

You might wonder why cars are forbidden here. When the auto industry started in the late 1800s, horse-drawn carriages were the standard for transport on the island and had been operating there for decades. They also played a part in the island’s transformation to a destination and, for many, reflected the unique culture. As cars gained popularity among the well-to-do families that could afford them, they also began to roll off ferries onto the island. Carriage operators petitioned local officials to prohibit what they called the “dangerous horseless carriages” that frightened their horses and fouled the air. The village enacted a ban on cars in 1898. Today the lack of cars makes the island different and a true escape from the noise, congestion, and pace of everyday life.

Aircraft, on the other hand, have become key to island commerce. Many would hesitate to visit without the option of flying, and air tours are also a popular attraction. Airplanes might be most important in the cold months: When the lake freezes and Mackinac becomes what some consider a true winter wonderland, an airplane might be the only way to get there.

CODA: Be Weather Mindful

Rapidly changing weather is always a consideration when flying in Michigan and the surrounding area. While I thoroughly enjoyed my time, I knew I could not rely on forecasts. Flight planning in this area means picking more alternates than usual, as our return would prove. About halfway through the flight to Allegan, the broken cloud layers converged from about 3,000 feet to above 10,000.

It was not nighttime yet, but the skies darkened enough that I could look through the engine cover vents and see the orange glow of turbochargers on the 414’s Continental TSIO-520s. The situation became increasingly dramatic as the sounds of rain, then freezing rain followed by hail rang through the cabin. The airplane felt solid, Sanderson and West were cool and professional, but there was absolutely no reason to stay in that storm.

We diverted to West Michigan Regional (KBIV) in Holland. Safely on the ground, we heard support for the decision to divert in the form of extremely heavy rain pounding the FBO roof. Lightning flashed. More aircraft arrived on the ramp, fleeing the deluge. Pilots and passengers entered the FBO, jackets drenched from the short walk.

The scene made a great case for ride-sharing. We called Uber for the 30-minute final leg to Allegan.
