" Pilots declare mayday fuel and are given a straight in approach..."
"...straight in approach...". Actually, when declaring an emergency; all traffic is cleared; you are asked what your intentions are; (where do you want to land that Roman Candle?); how many souls on board; how much fuel on board.
You can even do an "Indianna Jones"; and land on a taxiway.
OK I agree. If an airline pilot calls mayday fuel, that causes other airlines to burn more fuel to give the mayday plane priority to get on the ground. The point I was trying to make is this is an issue for short range EV planes..
