i think nose door for A380 have less sense because of upper deck and less available height on main deck

Re: Typical MD-82 Cruise Speed

traffic controller may not let you come to busy flight level because you too slow. This a frequent question here. Under radar control this is rarely an issue and I’ve got lots of time in slow jets—A-10 (usually not at FL), Citations (.60-ish) and the C-5 (.77). Most of the domestic time in the Cita...

Re: Costs and/or benefits of flying freighters non stop vs 1 stop on ultra long flights

I don't know what the rationale was for the decision but FX and other similar companies generally cube out an aircraft before it gets weighed out. So, given the winds and payload, they may be able to make the eastbound journey non-stop. The 747 family will generally get weighed out before it bets c...
