Talking about Cuzco(Peru)the biggest types using that airport are
737/727s.Most (all?)of the flights are scheduled for AM because landings are always on 28 and take offs on 10,the winds are generally westerly and usually exceed the tailwind limit for takeoff
by PM.Airfield sits at 10700ft with MSAs exceeding 20000ft and the temp.is around ISA plus 20.I remember being a pax out of there a couple of years ago,took off (732)and after 5mins or so of max chat/angle climb we were no more than 1000ft or so above the terrain,spectacular views though!
