On The Tarmac:IAFs First C-17 Globemaster III Heavy Lift Transport Aircraft

they look pretty in Indian color.

Can someone explain why? Landing at that altitude should be no different than flying. Taking off should be a problem, but why landing?

In High Alt environment, when you lower the engine output, your will kill the engine if air intake is not enough, i believe it called "Choke" on turbofan engine. And shutting down engine(s) on landing course is something you do not want..........

Somebody already explained why the different between C-17 and IL-76 so i am not going to repeat it.

But the question remains, the problem should be for taking off, why landing. The plane is already at speed, and is slowing down. It should be able to do it at lower thrust.

If it landed somehow then how you plan to take that aircraft down from that height.

 

[The A-5]

Dont know abt 30 but 16 of them will replace 17 IL76 currently in service and which are expected to retire in 2020

The no. of IL-76s in service is 24, not 17.

Its a good question.

The answer is in your question.

When air is thin the desired drag to slow down is not there.

Lowering thrust will make the plane fall/descend down fast not slow.

I think

For landing and taking off the engine need to inhale excessive air, which is not there or much thinner than sea level bases.

In case of lading the aero dynamics are made less streamline to resist the air, i.e the drag is increased. When drag is increased the plane needs more power to remain in the air for adjusting and aligning for landing. You have might have noticed how jet engine roar before landing. Up to this time the trust created is forward. After touch down at optimum time and at required stability, reverse thrust is generated to stop the plane completely.

The whole process behave in textbook fashion at ground level bases but at Himalayan bases the thin air makes it atypical operation and a job of a more efficient engines.

Please read and search more on it, I admit haven't read any material on this but is my poor effort to detail a bit on how things might be happening at higher altitude landings.

Are you new to the Interwebs, Sir?

Bharat Rakshak website [BR], quoted for this information has its articles quoted in articles & reports on .mil website. Gazillions of sites have this bit of info, not least of them being spotting websites.

The only folks who are unaware of this is the Royal Lesotho Navy.
