Helicopters. Rosaviatsiya validates Ansat high-altitude operation

Take-off and landing now allowed at 3500 m

Federal Air Transport Agency, the Russian Rosaviatsiya, certified the increase in take-off/landing altitude of Ansat helicopter to 3,500 m. Major change approval is issued on the basis of trials conducted in summer 2018 at Mount Elbrus. The document allows aircraft to operate in high-altitude conditions. 

Before that the aircraft take-off and landing altitude was limited to 1,000 m, restricting its use in elevated areas. During certification tests Ansat successfully completed a series of take-offs and landings at altitudes up to 3,500 m, including simulation of one engine failure and autorotation mode, thus confirming its capability to operate in high-altitude conditions.

It is a light twin-engine utility helicopter serially produced at Kazan Helicopters. As per the type certificate, the model design makes it possible to carry out quick conversion from cargo to passenger version capable to transport up to seven people. In May 2015 a major change approval was obtained for EMS version of the aircraft. Ansat is certified for operation in ambient air temperatures from minus 45°С to plus 50°С. In July 2018 a major change approval was obtained for extension of service life of its assemblies.
