V2500 bump
Wondering if anyone can help with a little tech issue i've seen twice now on the A320 with V2500 engines. After starting both engines and waiting for FADEC startup sequence to finish (grey box around N2), I've selected the guarded push button to activate bump thrust but it's only come up on one engine.
Obviously had to shut down both engines on remote stand and start again with fingers crossed. Quite frustrating but I have no idea why it does this?
