Maximum operating airport altitude for commercial jets
Hello,
I remember reading the maximum "recommended" altitude at which some commercial jets can safely land and take-off (i.e. airport/runway altitudes) and I recall that they were not that high and this confused me.
I wanted to confirm how high, say, a 737NG series or even Jumbo Jets (744's), or Airbuses (A320/A330/A340 series) can land and take-off with respect to airport altitude so that it can safely take-off within a reasonable distance I presume. For example, La Paz, Bolivia airport is well over 13,000 ft MSL!
Can commercial jets use these very high altitude airports without issues or do they need special modifications?
