Airbus Flight Path Angle
Hello everyone,
I was trying to find out more info on the FPA and how it works, but couldn't find much useful information on the net or the FCOMs.
Specifically I want to know how the wind affects the FPA selected?
Is my assumption here correct?
If at 10 dme and at 3000' I select a FPA of 3 degrees. The aircraft will fly a constant 3 degree angle down to a specific point on the ground. In the case of a tailwind, this point on the ground will not move forward nor will the descent angle become shallow.
As the tailwind increases the GS increases and the ROD will automatically increase to keep this 3 degree angle?
If there were some updrafts that pushed the aircraft 30' above the 3 degree angle, every subsequent dme vs alt check, I would be 30' high. Therefore causing my 3 degree FPA to be parallel with the initial 3 degree FPA, causing the original specific spot on the ground to have moved forward.
Thanks for your time and thoughts. I would also appreciate it very much if anyone can provide any references that I am looking for.
Cheers!
