Ultralight Aircraft

   Ultralight aircraft weigh less than 254 pounds empty, are single place, have a maximum speed of 55 knots calibrated airspeed, and must land at a maximum speed of 55 knot calibrated airspeed, a power off stall speed not to exceed 24 knots calibrated airspeed, and may have no more than 5 gallons of fuel.

   In photo 1 -  Powered Paraglider (Paramotor) is a form of ultralight aviation where the pilot wears a motor on his back which provides enough thrust to take off using an adapted paraglider or paramotor wing. It can be launched in still air, and on level ground, by the pilot alone — no assistance is required  .

   In photo 2 -  An ultralight trike, also known as a flex-wing trike, weight-shift-control aircraft,[1] microlight trike, deltatrike[2] or motorized deltaplane,[3] is a type of powered hang glider using a high-performance Rogallo wing coupled to a propeller-powered three-wheeled undercarriage. While many powered aircraft have three-wheeled landing gear, the term "trike" refers specifically to the form of aircraft described here. The principles of this page can generally be applied to the single-place ultralight trike and the two-place weight-shift control light-sport aircraft.
