So the RPM did not increase, even slightly, as the fuel flow went down and EGT went up?
So is this the unmetered fuel flow that is unstable? Or is it the metered fuel flow that is unstable? Or is it both? And if both, are they “unstable” in the same manner, ie., move up and down together?
A) No
B) Yes
C) No
Correct, RPM is stable as FF goes down and EGT up.
Both metered and unmetered FF are unstable in the same manner.
