Performance of early jets and fans at high Airports
This thread is a spinoff from 707 conversion from Jet to Fan engines as promised...
The question was whether aircraft fitted with these early engines experienced a reduction in MTOW at high airports like Bogota, Quto, La Paz.
Bogota & Quito are about 2,600m (~ 8,500ft) ASL. La Paz a fair bit more.
Piston engine performance was probably afected more.
Even today widebodies (747s and 340s) tankup in Caracas before a transatlantic hop rather than in Bogota. Not sure if this has more to do with the plane landing in Caracas 1.5 hrs after departing Bogota rather than a limitation in MTOF ( i.e. MLW is the issue)
By corollary from the previous thread it would appear that pure jets would fare better at high altitude airports than fans.
