Hindustan Aeronautics Limited’s (HAL) indigenously developed Light Utility Helicopter (LUH) demonstrated high-altitude capability in hot and high weather conditions in the Himalayas recently for about 10 days. The Company said in a release that a comprehensive test plan was executed at Leh (3300 metres above sea level or MAMSL) in temperatures up to ISA+320C, which included envelope expansion, performance and flying qualities.

LUH took off from Leh and demonstrated its hot and high hover performance at Daulat Beg Oldie (DBO) Advanced Landing Ground (ALG) at 5000 MAMSL. The helicopter also demonstrated its payload capability in Siachen glacier high altitude. During the trials, pilots landed the helicopter at the highest helipads of Amar and Sonam.
