I have 3 767-200s, let's call them A, B, and C. All have the same standard seating: 192/18.
They are flying out of SBSP, which has a runway of 1940m. They are all flying the same routes -- it is 197 nm.
A: runway requirement of 2130m. +15 tons weight variant. Has a range of 3770nm. No pax restrictions.
B: runway requirement of 1810m. standard weight variant. Has a range of 2300nm. Limited to 147 pax.
C: runway requirement of 1870m. +8.2 tons weight variant. Has a range of 3190nm. Limited to 176 pax.
I do not understand! If B & C have runway requirements of less than 1900m, but the runway is longer than 1900m -- why are they being limited?
And they are all flying very short routes, so they should not be carrying much fuel, and therefore runway length not really an issue, right?
