Skyrock 4 Posted June 7, 2015 Share Posted June 7, 2015 Hey folks, today I tried to compare my biases for the B777-300ER and thus entered all the needed values in the evaluate option within the aircraft editor. I noticed that the temperature entered does not affect the performance at all. No change in the TAS or in the fuel flow whatsoever. The biases also do not change. I entered values which equal ISA devs of +10, +20 and even +400 didn't affect the performance numbers. Is this a general problem in PFPX or is there a bug in the evaluation? The 77W does not have any ISA dev tables in the .txt file, may this cause the explained phenomenon? Link to comment Share on other sites More sharing options...

Emi 5161 Posted June 12, 2015 Share Posted June 12, 2015 Best will be if you submit a ticket directly in the flight sim soft ticketsystem. This would be rather something for the developer to answer than for us or another user. Link to comment Share on other sites More sharing options...
phil747fan 52 Posted June 12, 2015 Share Posted June 12, 2015 Hello, of course if there is no ISA charts fed there is no ISA difference on the calculation. biases worked on different profiles also, so that -300ER is maybe missing some parts. which Airplane profile is it coming from? the one from PFPX or from another developper? just a beta tester and aircraft profile creator.

Skyrock 4 Posted June 12, 2015 Author Share Posted June 12, 2015 The -300ER profile is the standard one from PFPX and has no ISA deviation charts. However, above each chart table, there are two lines which represent the TAS and fuel flow adjustment at ISA deviation. The calculation also works fine, yesterday I flew VHHH-RJAA and had an average ISA deviation of +12 and the actual numbers machted the calculated ones almost perfectly, so it means that in general the temperature is taken into calculation. The only issue I experience where temperature does not have any influence on the biases or on any number (fuel flow, TAS) at all is in the evaluate option. I will consider opening a ticket. Thanks for your answers! Link to comment Share on other sites More sharing options...
phil747fan 52 Posted June 13, 2015 Share Posted June 13, 2015 Skyrock, yes a ticket is maybe the solution. i checked on some of the data i have and between isa 0 and let s say isa+10 there is no linear fuel flow or speed adjustment so some short or cut offs has to be made for users. otherwise the file will be bigger.

Skyrock 4 Posted June 14, 2015 Author Share Posted June 14, 2015 I opened a ticket and got the following answer: FlightSimSoft.com | Christian Grill (FlightSimSoft.com) Jun 14, 22:52 There is indeed an issue in the present release, not taking into account ISA deviation in cruise. Issue will be fixed for next release. Great to hear! Thumbs up for the quick answer. Link to comment Share on other sites More sharing options...
FlyPrecisely 124 Posted July 10, 2015 Share Posted July 10, 2015 The issue is still remaining in v1.22. Link to comment Share on other sites More sharing options...
Skyrock 4 Posted July 10, 2015 Author Share Posted July 10, 2015 Hmm for me in V1.22 it works now. The values change when the entered temperature changes. Link to comment Share on other sites More sharing options...

I've just had to reload the appropriate aircraft types.Regards,Mykyta Link to comment Share on other sites More sharing options...

Regards,MykytaHi, please describe what you mean by "reload the appropriate aircraft types", did you have to delete the aircraft you setup and recreate it?

Yes, that's right. Just backup the current airframe, remove it and add once again. Link to comment Share on other sites More sharing options...
