used for SAR/Casevac!
the Mi-17s are very rugged, dependable and versatile helos and are well liked by both army and AF pilots.
Sir i dont ot like the suggestion of MI-17 helo used by PAF for SAR and CASEVAC. Let me define both categories
AIR Force SAR helicopter. considering airforce SAR helo is to go in hostile area, enemy area for rescuing a downed pilot, the bird must be small, low profile, less noisey, can fly easilly nap of earth, terrain hugging mode, highly manoeuvrable, using terrain to mask itself. Offcourse, it has to rescue only one pilot may be 2, if wingman is also shot downed0, so big helo is not needed. Birds like Allouette (already used by PAF, Fennec, AS350, Bell 206 Jet ranger, Bell 412 are best suited for such operation.
MI-17 is big, noisey, cannot fly terrain hugging due to size, and whats the luxery sending 30 seater just to pick one or two pilots.
CASEVAC MI-17 is designes for mass casuality evacuation from the battlefield, earthquake, natural disaster, and helicopter must land on the ground, and troops, civilians, will enter from rear or from side doors. MI-17 is not recommended to pick casuality while hovering overhead. Bigger rotor, bigger rotor wash, and more dander of flying debris in the area, hitting and injuring the casualty being lifted or hoiest up. Also casuality tray with patient may swing more right and left. again, if a casuality is to be lifted overhead, smaller helicopters produce little downwash from rotors.
So MI-17s are designed for mass casuality evacuation afetr landing on a landing zone. not good, suspending an 8 ton giant in air picking up a poor chap just ejected from a fighter.
