PERF FACTOR

Recommended Posts

Hey guys,in A/C STATUS, there's a performance factor field which CAN be edited. My guess is that it allows the operator to modify fuel flow and performance figures to mach real world aircraft performance. But what does it affect? Only fuel flow, or other parameters also? I can't find any thing about it in Aircraft Systems or the FMS guide.Xander

I know for sure that it affects fuel predictions. Perhaps it also modifies climb descent profiles, but I'm just guessing. A brand new plane off the factory floor will have 0 set. Over time, each airframe will have a different perf factor. This field is usually modified by maintenance, and only verified by flight crew. Although it can be changed in the PMDG FMS, I'm yet to see any impact on FMS predictions. That's fine with me though, because that seems to be a bit outside the scope of a $90 sim.Paul
