I am a Commercial Pilot, Flight Instructor, Plane Spotter, and Frequent Flyer. Come along with me as I travel the world, share plane spotting memories from 1997 and beyond, and fly my 1967 Mooney M20C.
I once was on a WestJet flight where we had an aborted takeoff, went back to the gate without leaving the plane so the pilots could configure some stuff and adjust to do manual changes, and then tried a take off again but that also failed! Spent about 6 hours in a plane just to not leave the ground. After that they cancelled, and told everyone to come back the next day using the same plane after a maintenance team arrived. The problem was a clogged pitot tube.
Sounds like a flight I had recently from ORD, except it included snow, deicing, a 4h delayed inbound aircraft/crew, and a "TCAS error" that sent us back to the gate, leading to a maintenance investigation, crew timeout, and cancelled flight.
Here is my video of our aborted takeoff of a Delta 757 in May 2023. We were definitely rolling at takeoff power at the time. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ADf7FndTBFo.htmlfeature=shared
The "whale sounds" on A220,s is because of the geared engines vs regular turbofan engines. They are more efficient & like most all newer turbofans quieter overall BUT in lower idle & accelerating times its the sounds of the engines changing gears and moving the points of combustion which essentially causes changes in pressure over the combustion cone which amounts to similar physics like blowing over a bottle to make that weird noise like fog horns or train horns.
That’s true, I looked up what caused it and in the combustion chamber when it is engaged to full power or almost any acceleration from idle the resonance frequency within the chamber causes this phenomenon “whale noise” pretty cool actually
