The requirements of high altitude operation are relatively simple and can be inferred from the basic physics encountered within the scope of the momentum theory and blade element theory. Operating a helicopter in hover mode in high altitudes implies that the induced velocity would be high, which implies a correspondingly large power requirement. So it is apparent that the installed engines would need to have a high power rating. However, just increasing the installed engine power is not a sure shot solution since the rotor blades stall needs to be avoided before peak operational altitude is achieved.
