HAL’s Light Utility Helicopter clears tests in Himalayas


BENGALURU: Hindustan Aeronautics Limited said on Thursday the Light Utility Helicopter (LUH) designed and developed by it successfully demonstrated hot weather and
high altitude capabilities in the Himalayas.

With the completion of hot and high altitude testing, the LUH has complied with all the requirements of the users and it was close to operational clearance certification, HAL
Chairman and Managing Director R Madhavan said.

The trials were carried out by the test pilots from HAL, the Indian Air Force and the Army from August 24 to September 2, he said in a statement. “All planned tests were successfully demonstrated”, the statement said.

A comprehensive test plan was executed at Leh (3300 m altitude) in temperatures up to International Standard Atmosphere (ISA) +32 degree C which included envelope
expansion, performance and flying qualities, according to HAL.

The LUH then lifted off from Leh (Jammu and Kashmir) and demonstrated its hot and high hover performance at Daulat Beg Oldie Advanced Landing Ground at 5000 m followed by another forward helipad (5500m at ISA + 27 degree C), it said.

“While these extreme weather conditions imposed flight restrictions on all other civil and military aircraft, LUH flights were unhindered as it is designed for such
operations”, the company said.
