Re: Business Risk for Boeing: The A321XLR

Re: Electric Taxiing Solutions

Main engines are designed to produce fairly constant high levels of thrust in a cold (-50C) thin air environment. Running at idle in thick warm air, with sudden power surges for acceleration, is far from optimal. Additionally, the thrust output is continuous, but the aircraft does not need to accele...

Re: Shape of fuselage

Just looking through pics of old aircraft, I'd say there is a transition during the 1930s from boxy designs to fully rounded designs, with an intermediate step being boxy-with-rounded-corners (à la Ju52, or many French designs of the era, like the De332) I'd venture a guess and say this is likely du...
