Hello All of you Technical people. How are you?
My question today is about the 717... Again.
I noticed when the pilot throttles up, There is a sound that sounds like Air Whooshing right through the overhead bins. The pilot will advance the throttles, and you will hear the engine accelerate, and at the same time you will hear the WHOOOOOSSSSSHHHHHHHH.
Also, I have noticed that while sitting at the gate, there is this whining sound that goes like "EEWMMPH" every 5-6 seconds. It sounds like it is coming from the Cargo area. Can anyone explain this?
Thanks for your help.
