Hi there,
Want to gain more knowledge. Pls advise.
I'm reading about managed descent and i have a couple of questions that i would like to ask.
Quote from FCTM:
if the aircraft gets low on the computed descent path, the speed will decrease towards the lower limit of the speed range. When the lower speed limit is reached, the A/THR reverts to SPEED/MACH mode and applies thrust to maintain the descent path at this lower speed. A similar path intercept point n will be displayed on the ND.
When the aircraft gets too low, why would the speed decrease? Won't the A/T bring the speed back up? Is there like a fixed speed at which airbuses fly at when descending? How is the speed decided?
Thanks
