...you question the choice of equipment! you obviously have no clue how aircraft work
Runway length! Airfield elevation! Pressure altitude! OAT! obstacles! it affects every type of aircraft!
So, one chap says they are and others are saying they are not performance limited in hot /high conditions? I'm puzzled by the disagreement with my questioning the suitability of the Tristar for the current military requirement. Whatever; the airlines operating them dropped them from their fleets when aircraft better suited to their operational needs arrived on the scene - even though they were low hour machines - and military air transport needs are not that different from the civilian environment.
