BENGALURU: Hindustan Aeronautics Limited’s (HAL) indigenously developed Light Utility Helicopter (LUH) completed the hot and high-altitude trials in the Himalayas, said reports on Wednesday (September 9, 2020).

The LUH demonstrated high altitude capability in hot and high weather conditions at Daulat Beg Oldie in the Himalayas for about 10 days.

A comprehensive test plan was executed at Leh (3300 meters above mean sea level) in temperatures up to ISA (international standard atmosphere)+320C which included envelope expansion, performance and flying qualities, Bengaluru-based HAL said.
