Atec Zephyr



This aerodynamic, cantilevered, low wing sport pilot aircraft of mixed construction can transport two people over 800 statute miles at a maximum cruising speed of 155 mph. The Zephyr has a composite exterior but wooden wings. It all begins with a 200 to 400 foot ground roll on a grass or concrete strip and a maximum climb rate of nearly 1,700 feet per minute.

Developed in collaboration with renowned Czech aircraft designer, Oldrich Olsansky, the ATEC Zephyr Sport Pilot airplane made its debut around 2000. By 2008 over 110 units were flying in Australia, Europe and North America.

The options are Sport Pilot, Amateur-built (Experimental in the U.S.) or Ultralight (Canada only; Advanced Ultralight pending). By opting for the first category, operators can enjoy all of the benefits of a fully-certified aircraft and can train student pilots in a flying club environment. For those who no longer qualify for the standard aviation medical, the Ultralight and Sport Pilot categories less restrictive requirements may be the answer.

The MTOW is 472.5 kg in the European ultralight version and in US the LSA version of the Zephyr allows 550 kg. The LSA Zephyr is called Zephyr 2550.
