We have an A330 aircraft with FMS1. We use Idle factor of 8.5% for this aircraft. Also we have advised to reduce 3% of the Performance factor we get from Airbus PEP programme. So we we get Perf factor of 2.5% we introduces minus 0.5%. Can a Perf Factor be a minus figure and what is the correct method for giving the Perf Factor for A330s with FMS1.
Tks and regards/ gsk
