[4] No 109 HU had been thrust into action right from the moment of its birth when, in 1962, the Sino-Indian War Broke out.

The unit maintained a two aircraft detachment under the Eastern Air Command, which served extensively in CASEVAC and logistics missions in and around the Spiti Valley.

Following the war, 109 was deployed in a number of different roles, from supporting the Border Roads Development Organisation, in the North East India, to flying in support of disaster relief following the Jagadhri floods in Uttar Pradesh in 1963.

The military role of 109, however, again came into calling when riots broke out in Srinagar in January 1964, preluding to the Second Kashmir War.No 109 HU was heavily involved in the tactical airlift of troops and security personnel into the sensitive areas in the valley, and was also heavily involved in reconnaissance and patrol missions.
