Grandfathered Trainers Are Golden
By Dan Grunloh, Editor, Light Plane World

The new FAA guidance for issuing a Letter of Deviation Authority (LODA) for flight instruction has changed the picture for some experimental light-sport aircraft (E-LSA) that were previously used for training but had to stop almost a year and half ago after the end of the transition period. There are also new provisions for training in experimental gyroplanes and for ultralight-only training in experimental aircraft flying under 87 knots. Read more

Commercial Trike Pilot Certificate Needed
By Paul Hamilton
Now that the sport pilot / light-sport aircraft (LSA) has been around for a while, we need a commercial pilot certificate for the weight-shift-control trike (or weight-shift control certificate as the FAA would call it) for compensation and hire. This way we could provide tours, inspect utility lines, crop-dust, fly cargo to land like helicopters in small areas, search/rescue, farm, game count, become part of law enforcement - the list goes on. Use your imagination. Read more Paul Hamilton

'World's Smallest' Air Show
The big story at the 17th annual "World's Smallest" Air Show at Brian Ranch Airport May 28 to 29 was the big wind. By 7:30 a.m. on Saturday it was already gusting in the mid-teens, and by mid-morning it was varying between high teens and mid-twenties.  World's Smallest Air Show
The two-runway airport and U-pick fruit orchard are owned by the husband and wife team of Jack Brian and Felice Apodaca who staged the free event. Read more
Dave Sykes Crosses India on His Solo Flight to Australia
Flying across Europe and the Mediterranean countries in an open-cockpit P&M Aviation Quik trike must have felt like a vacation to Dave Sykes compared to his later experiences in Egypt, Saudi Arabia, and Oman. There aren't many sandstorms in York, England, where he began his 11,600-nautical-mile flight to Sydney, Australia, on April 28. After six weeks of flying, he has crossed India, entered Myanmar (Burma), and is more than halfway to his goal. Read more Dave Sykes
LODA Revision Opens Doors for Flight Training
A point of emphasis raised at February's EAA/FAA Recreational Aviation Summit has brought results with re-opened avenues for flight training in the low-and-slow end of aviation. In revised FAA Letter of Deviation Authority (LODA) guidance, publicly released this month, changes allow for primary flight instruction in rotorcraft gyroplanes, ultralight vehicles, and sport pilot certificates in previously exempted experimental light-sport aircraft.  Read more LODA Revision Opens Doors for Flight Training

Former Military Pilot Flying Again 40 Years Later
Members of "The Greatest Generation" are leaving us daily, but at least one sees heaven in lower altitudes. This is the unique story of Victor Hernandez, and it demonstrates a triumph of human dedication and perseverance. Victor, a native of Puerto Rico, is an 89-year-old World War II P-47/P-51 pilot who had the dream late in life to fly again.  Victor Hernandez
He realized that dream on April 27, 2011, the date he earned his sport pilot certificate. It is an amazing story of purpose, perseverance, determination, energy, and a dream that wouldn't die. Read more
Flying With Ethanol
There has been a lot of discussion going around the light-sport and ultralight community about alcohol in the fuel. Can we use it? Is it a good idea? What is legal? It's probably one of the questions I'm most asked. Let me start by addressing this question from a legal point of view, and then I'll work to the practical side. If you're flying a special light-sport aircraft (S-LSA), then you must use the fuel specified by the aircraft (not engine) manufacturer. Read more Flying with Ethanol
Taxi Practices and Safety
The airplane's natural environment is in the air. In that element it is graceful and maneuverable - a thing of beauty. On the ground it is ungainly, difficult to maneuver, and has a propensity for coming to rest against other objects, thereby becoming ugly and loved only by an insurance adjuster. As a result, most primary flight instructors teach some basic taxi rules. Read more Bob Wright

World's Smallest Air Show 2011
Brian Ranch Airport, Llano, California
Step right up and see the World's Smallest Air Show. That's right folks, see the flybys, the carrier landing competition, and the World's Smallest Flightline due to high winds. But there were lots of sun and smiles. Photos and captions by Dick O'Reilly, EAA 661656. View the gallery

Q.  Should my plane have a fuel mixture control?

A. Carburetors are normally calibrated at sea-level pressure, where the correct fuel-to-air mixture ratio is established with the mixture control set in the full rich position. However, as altitude increases, the density of air entering the carburetor decreases, while the density of the fuel remains the same. This creates a progressively richer mixture, which can result in engine roughness and an appreciable loss of power. Read more

Powered Parachute
Q. Why does my powered parachute seem to have a longer ground run in a crosswind?

A.  As the nose wheel is being raised off the runway, the steering control for the powered parachute is transferred fully to the wing flight controls. If a significant crosswind exists, it will take longer for the powered parachute to take off because the steering control adds drag to the wing. Read more

Weight Shift Trikes
Q. What are some advantages of weight shift trikes?

A. Simplicity in the control system, interchangeable wings, easy to transport and store, short takeoff and landing performance, and broad speed range. Trikes offer the most birdlike flight; when holding the control bar the pilot is in fact holding the wing. This offers an element of connection to the air that any other aircraft can't duplicate. Trike wings offer exceptional stability; many trikes can be operated safely without the need for an airspeed indicator.

Fixed-Wing Airplane
Q. How should power be set during approach to landing?

A. Power can be used effectively during the approach and roundout to compensate for errors in judgment. Power can be added to accelerate the airplane to increase lift without increasing the angle of attack; thus, the descent can be slowed to an acceptable rate. Read more

Q. What is a gyroplane prerotator?

A. Prior to takeoff, the gyroplane rotor must first achieve a rotor speed sufficient to create the necessary lift. This is accomplished on very basic gyroplanes by initially spinning the blades by hand. The aircraft is then taxied with the rotor disc tilted aft, allowing airflow through the system to accelerate it to flight rpm. Read more
