For what i have experienced until now no airport created me problems/struggles in landing at or taking off from, but there is one, thiugh i can land at without problems, wich i struggle in taking off from with boeings big size aircraft: El Alto International Airport in La Paz, Bolivia. If i try to take of from the beginning of the runway 28, the plane lifts from the ground at about one kilometer and half from the end of the runway. I have always to reverse it the more backward i can from the begin of the runway, keep the parking brake on whil thrust is maximum for about ten seconds before leave it and make the aircraft start in rushed acceleration. And i am speaking about 13150 feet, if not a bit more of runway length. And i speak of taking off from runway 28, if i try from runway 10, then there is no hope to lift from soil without bumping on the hill ahead. This with big planes like Boeing 747-8I, Boeing 777. If use medium sized airliners or smaller aircraft line Longitude, TBM930, piston/turboprop, having shorter take off ranges, then no problem in either the sides. But i set off no wind clear skies as meteo conditions. I know that is due to the 4050 meters of altitude, so the aerodynamics are more though because of less air. So my question is, at this point, if a Boeing 747, 777, 787-9, an A380 or another big sized plane could or not take off from that andean airport…
La Paz is one of the most difficult airports in the world as far as performance goes. I would advise doing performance calculations for any takeoff from such a location, it might be possible some planes, particularly the bigger ones or ones with worse thrust-to-weight ratio won’t be able to take off from there at all, and some other ones might be severely restricted by maximum takeoff weight. However, many airplanes don’t even COME with performance data for takeoffs at this altitude (PMDG DC-6 takeoff speed chart ends at 8,000 ft)
Exactly. This happens at El Alto because of its height, but also happens at other airports due to their location and surroundings (Paro -VQPR- for example).
In case of El Alto, with the Dreamliner you can’t take off at max load and max fuel. With max load, fuel has to be around 50%, and even then it’s a very slow climb and somewhat unstabilized take off.
On the contrary, in Paro you need to be light because as soon as you take off you need to climb a lot.
This is very common and for each airport with not-standard characteristics calculations should be done in order to properly operate from/to them.
