Forcing long distance alternate? Pfpx ignores airport

Recommended Posts

On some routes I try to plan an alternate that is a long distance from the destination airport.

Pfpx ignores my alternate if the distance is too long.

Pfpx puts ALTN in place of the airport code and gives 0 fuel in the plan

Is there a solution to forcing Pfpx to use the one alternate I have selected? Thanks.

Phil did ask for the OFP, it would be useful to know which aircraft performance file is in use also.

 

Works for me:

How is an OFP layout the cause of an alternative not displaying? I will try with the default OFP format

The OFP format maybe one cause of the discrepancy if not correctly coded, in addition the OFP provides more information than that provided.

 

Again the aircraft performance file in use ? as this may cause issue also.

Still cannot reproduce the problem, see attached.

PFPX v2.03

LIDO OFP template v1.05

Default B737 entry with 737-700_B24B26_v1.00.per

Default US Flag fuel policy

 

Any changes to the fuel policy or aircraft entry ?

Worked correctly here too today. That was odd. I attached a plan I did a few days ago KJFK-TXKF where I had the same issue. No fuel given for an Alternate. the atc flight plan says ALTN rather than KORF but at the bottom the route maps it does show a flight plan going to KORF for the alternate!

Could you post a snapshot of the general tab for the aircraft registration.

Weather could have been not good enough for that day and it ignored it? Thats my one guess...

I edited my post quickly adding that the route map at the bottom of the plan did show a plan to KORF but no atc plan ALTN and no fuel given for it.

I had wondered if the ceiling/visibility was affecting the outcome but I do not believe so.

 

However it looks like you are not using the AirlinerPerformance profile, select the Info button to compare to this:

Must have forgotten that I changed the file back to default, my landing fuel remaining was low with the airlinerperformance file after each flight
