When the first batch of the historic Cheetah and Chetak helicopters reach the end of their Total Technical Life (TTL) in 2027, the Army will begin to phase them out, while it looks to replace them with a larger number of indigenous light utility helicopters (LUH), Indian Media reported.
Difference Between Cheetah and Chetak Helicopters
Amid the replacement of the Cheetah and Chetak helicopters, Air Marshal G.S. Bedi (retd.), distinguished fellow at the Centre for Air Power Studies (CAPS), told Sputnik India, “Prior to their induction, these helicopters were intended to serve as Air Observatory Posts, nevertheless, as weaponry technology advanced, new roles in communication became available - the Cheetah and Chetak were inducted into the Armed Forces”.
Advanced Light Helicopter Dhruv to Replace Cheetah and Chetak
The Indian Armed Forces planned to replace the ageing and outdated Cheetah and Chetak with the Dhruv Advanced Light Helicopter due to the crucial operational void and their advanced age, said Bedi.
Indigenisation Aircraft Wave in India
Addressing India's indigenous aircraft, the air marshal insisted that much like HAL is replacing its ageing fleet of MiG-21s with Tejas Mark 1-A fighter jets, in a similar fashion for the Cheetah and Chetak helicopters— India would prefer to have home-made aircrafts.
Effect on Defence Personnel
Furthermore, the lack of weather capabilities has prevented the Cheetah and Chetak from flying at higher altitudes over clouds for extended periods of time. Additionally, their autopilots and navigational aids have been insufficient. It was therefore necessary to maintain constant contact with the ground. This was the primary cause of multiple mishaps, said the air marshal.
Having said that, visual aids are necessary for landing, take-off, and navigation, while the ALH Dhruv's fully autonomous digital engine management and considerably easier maintenance owe to its expressive features.
