Wing Commander Nand Kishore Shankarrao Ambegaonkar was commissioned in the Flying (Pilot) Branch of the Indian Air Force on 30 November 1955. During the period that Wing Commander Ambegaonkar worked as Chief Instructor, the Transport Training Wing underwent a change from Dakota to HS-748 aircraft for training. This transition phase was a difficult period replete with innumerable Flying and maintenance problems. It was entirely due to his relentless endeavours and untiring zeal that the changeover was remarkably smooth and without any serious delay in training schedules.

Wing Commander Ambegaonkar has 8,400 accident-free flying hours to his credit. He holds an 'A-2' instructional category on both Dakota and HS-748 aircraft, and 'A' Master Green Transport rating. It was under his personal guidance and control that the training schedules were recast and the entire training machinery streamlined, which helped a great deal in elevating the standard of training.

Throughout, Wing Commander Nand Kishore Shankarrao Ambegaonkar has displayed outstanding professional skill, high organizing ability, devotion to duty and zeal and capacity for sustained hard work. He has thus rendered distinguished service of a high order. The President is pleased to award him Vishisht Seva Medal.
