PFPX Dispatch data for 747-400s

[Will]

PFPX is pretty comprehensive, but the 747-400 model files that I'm familiar with leave a few fields blank.



I'm wondering if anyone has any real-world data (or real-world opinions) about the empty boxes:

Take-Off Burn vs. Take-Off Time
Approach Burn vs. Approach Time
Go Around Burn
Min T/O Fuel
MinFuel at Dest

And then under operating cost:

Fixed/FlightHour
Var/FlightHour
Delay/Hour
Delay to

Does anyone who uses PFPX have any entries in these boxes?
What might be real-world values/uses?
Or are they ignored?
Comments?

Thanks.

PFPX is pretty comprehensive,

Min T/O Fuel

Ill leave the other detail up to the real world dispatchers. I have scoured my Singapore Airlines Cargo documentation & buried in the minutiae of the small print I found this nugget:

B744F Min T/O Fuel = 30,000kgs (66,139lbs)

I shall amend my PFPX SQC files ... for those that use these files ... do you want me to arbitarilly add these figures for all the PFPX files?

Its the time, fuel, and distance to and from 1500'. Most carriers dont put it in a performance profile in their systems and all is well...

Okay thanks, that's helpful.

All the PFPX Aircraft files I make available for download have been arbitrarily amended with minimum take off fuel added, plus minimum RWY length & width details & fixed operating cost per hour (Circa USD $20k p/hr).

Very good! I'll take a look tonight.
