Search and Rescue Squadrons (Nos. 81 to 86)
A total of 6 Squadrons (Nos. 81 to 86) provide local search and rescue cover at the air bases at Peshawar, Sargodha, Rafiqui-Shorkot, Masroor, Samungli-Quetta and Mianwali. In each case, two Alouette IIIs are operated. The primary mission is to recover downed crewmembers and other isolated personnel.
SAR operations return key personnel to friendly control, allowing them to fight again. Secondly, SAR operations often influence the course of national and international politics by denying adversaries the opportunity to exploit the intelligence and propaganda value of captured personnel. Lastly, the presence of a robust and viable SAR force increases morale, with a resultant increase in operational performance.
Alouette III helicopter was developed from the Alouette II, with larger cabin, greater power, improved equipment and higher performance. The prototype flew for the first time on 28 February 1959, and a total of 1,455 Alouette IIIs had been delivered for civil and military operation in 74 countries by 1 May 1985 which was the final year of production by Aerospatiale.

Two baggage holds in centre-section, on each side of the welded structure and enclosed by the centre-section fairings. Provision for carrying two stretchers athwartships at rear of cabin, and two other persons, in addition to pilot. All passenger seats removable to enable aircraft to be used for freight-carrying. Provision for external sling for loads of up to 750 kg (1,650 lb). One forward-opening door on each side, immediately in front of two rearward-sliding doors. Dual controls and cabin heating optional.
