Confessions of a powered pilot

I had been offered glider flights in the past, but I would respond with “someday.” I had heard the arguments for it: It’s so quiet, you only hear the wind over the canopy; it makes you a better pilot. I had watched gliders fly over my apartment on approach to landing at the Frederick, Md., airport. But I was reluctant. I just wasn’t comfortable going up in an aircraft without an engine.

That changed June 1 with my first soaring lesson. I needed to gather aerial video footage for a story about the Central Indiana Soaring Society and the Alexandria airport the club purchased in order to keep it from being closed. Experiencing their soaring operation firsthand also would give me a better understanding of why this club went to such lengths (and expense) to save the airport. (See the video at 17:51 in the June 12 AOPA Live This Week episode.)

I met John Earlywine, a veteran instructor at the club and competitive glider pilot, and learned about his composite DG Flugzeugbau DG-1000.

For something I had always imagined as one of the purest forms of flight, I was surprised at how unnatural getting settled in the glider felt. Earlywine chuckled when I asked if I needed a headset. (While I didn’t think I would need one to talk to him, I wasn’t sure about communicating over the radio. Turns out, he had a mic in the back.) Once in the glider, I felt like I was practically lying flat and kept trying to move up in the seat until I realized the canopy wouldn’t close. For a Cessna 172 pilot who is used to sitting in a chair-like position, this new position, akin to lounging in a beanbag, took some getting used to.

Being pulled aloft by a Piper Pawnee piloted by Kris Maynard made me forget about my nerves during the preparation. After accelerating down the runway behind the Pawnee, with only the sound of the glider’s tire rolling over the asphalt, Earlywine lifted the glider into ground effect and held it about three feet off the runway until Maynard was ready to climb out. Once we were about 1,000 feet in the air, Earlywine left me fly on tow. Flying on tow is similar to flying formation in trail. Earlywine counseled me to pretend the Pawnee’s relationship to the horizon was my attitude indicator, to make uncoordinated turns to correct getting out of line with the tow plane, and to look past the Pawnee as if I were flying an ILS. All of that was easier said than done. I had a couple of formation lessons a few years ago but had forgotten about the uncoordinated control inputs used to keep the aircraft in line with the lead. Each time I entered a coordinated turn to realign with the Pawnee, I shot past and Earlywine helped me recover back to the center.

Once at 3,000 feet, I pulled the tow release and Earlywine instructed me to start hunting for lift. Cumulus clouds would have made it easy to spot the thermals, but this day was clear and sunny, except for a few wispy cirrus clouds. I started looking for large areas of asphalt or dark fields that might offer some rising air. We also circled over the town of Alexandria.

Finally, I found some lift to recover the couple of hundred feet that I had lost while searching. After regaining altitude, I took a minute just to look outside. I realized that I had been tense—almost as tense as I am in the dentist’s chair—up to that point. But the beauty of flight became very real at that moment, and I relaxed. I actually felt as if I were flying freely because the bubble canopy allows an almost uninterrupted 360-degree view; the pilots sit in front of the wings; and the nose of the glider is slender. The only sound was the rush of the air flowing over the canopy, quieting as I slowed and growing louder as I lowered the nose to gain airspeed.

While circling in the thermal, I had a tendency to do what Earlywine said most powered pilots do: pull the nose up into a climb. In soaring, climbing in a thermal doesn’t mean a “climbing turn” in the sense a powered pilot is used to. We circled and climbed in the thermals with the nose slightly low. The more lift we found, the higher pitched one of the instruments chirped, and the higher pitched Earlywine’s voice grew. Whenever we flew out of a thermal, the chirp turned to a monotone and Earlywine would “turn off that annoying sound.”

Finding lift became a game for me. I wasn’t thinking about getting from Point A to Point B, although with the glider’s 47:1 glide ratio, from 3,000 feet we could have flown to Indianapolis Regional Airport where the glider club had been the day before for AOPA’s regional fly-in. I was only focused on finding that precious lift to stay aloft. I nearly forgot one of the original purposes of going for the flight: gathering video footage. Giving Earlywine the controls, I started filming while we maneuvered and Earlywine brought us in for a landing.

I had been looking forward to flying the pattern and landing but videoed it instead. That gives me all the more incentive for another glider flight!

The autopilot turns 100

Wednesday, June 18th, 2014

It seems hard to believe, but the first aircraft autopilot was demonstrated 100 years ago today. On June 18, 1914, Lawrence Sperry let go of the controls of a Curtiss C-2 biplane, stood up in the cockpit, and raised his hands high above his head. The crowd below roared its approval as Sperry’s mechanic then walked out onto the airplane’s wing–and it remained in level flight.

This took place above the Seine River during France’s Airplane Safety Contest. A total of 57 “specially equipped” airplanes, featuring such innovative technologies as magnetos, self-starters, and carburetors–all still used today–competed for a prize of 50,000 francs (about $10,000). Sperry was the only one to demonstrate a gyroscopic stabilizer, and won the prize. In 2004, Aviation History presented an interesting article about the flight; it can be read online

Sperry’s father, Elmer, had developed the gyrocompass–at the time, a massive affair that had been installed on a number of U.S. warships.

Lawrence Sperry’s flight also marks the centennial of Honeywell Aerospace, which is one of four business divisions of 129-year-old Honeywell. Through organic growth, acquisitions, and mergers of legacy companies, Honeywell Aerospace can trace its heritage back to Lawrence Sperry (click the link and scroll down the page). The Sperry Gyroscope Company became Sperry Corporation, much of which moved to Phoenix in the 1950s and became the Sperry Flight Systems Company–today a part of Honeywell Aerospace.

Other firsts for Honeywell Aerospace include the first gyro horizon and directional gyro, cabin pressurization, the first gas-turbine auxiliary power unit, the first ground proximity warning system, and the first 3-D airborne weather radar. An interactive anniversary website details this evolution. Sperry’s accomplishment finds itself in good company a century later.
