The Soaring Concepts Sky Trek is an American powered parachute, designed and produced by Soaring Concepts Inc of Sturgis, Michigan and introduced in 2000. The aircraft is supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction.[1][2]
Design and development
The Sky Trek was designed to comply with the US light-sport aircraft rules and is on the list of Federal Aviation Administration accepted LSAs. It features a 500 sq ft (46 m2) parachute-style wing, two-seats-in-tandem accommodation, tricycle landing gear and a single 64 hp (48 kW) Rotax 582 engine in pusher configuration.[1][3][4]
The aircraft carriage is built from large-diameter 4130 steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates adjustable gas shock suspension.[1][5]
The aircraft has an empty weight of 384 lb (174 kg) and a gross weight of 950 lb (431 kg), giving a useful load of 566 lb (257 kg). With full fuel of 10 U.S. gallons (38 L; 8.3 imp gal) the payload for crew and baggage is 506 kg (1,116 lb).[1][4]
The standard day, sea level, no wind, take off with a 64 hp (48 kW) engine is 200 ft (61 m) and the landing roll is 100 ft (30 m).[4]
Operational history
In August 2015, 24 examples were registered in the United States with the Federal Aviation Administration, although a total of 25 had been registered at one time.[6]
