Hi Francesco, I hope the guide is a help. There are a few format issues with the file, but on initial sight the biggest question is that you only include climb data up to 29000ft. If you have that then it should be quick and easy to get the rest of the file sorted out, though this won't be suitable for short sectors as you only have Mach cruise data from FL250 and above. Cheers Jon

Well we've proved this forum isn't dead, so there's a positive. Everyone's entitled to an opinion, and a few people seem to be quite vocal in expressing theirs. I've expressed mine above, and to me this subject is akin to that favourite question of flightsim forums - "when's the release date?". Again I'm taking the positive view that PFPX works very well. What I paid for works and the developer hasn't failed to get the servers back up when they've had an outage. I got what I paid for. The developers don't owe me anything else. That's my reality.

Have you read the topic title Ray? No misquote, that excerpt from your post is a good answer to the question posed by that title. From here on I'll just be feeding the trolls.

If PFPX was "dead" then why would the servers be online? It continues to be one of the best bits of software I've spent my hard earned dollars on.

The main obvious difference of the 747-400D is that they were not fitted with winglets. On most Boeings which had winglet option as retrofit the fuel burn saving is around 3-4%, so the burn on the 400D will be higher. On the very short domestic sectors those aircraft flew the additional burn wasn't huge and was offset by weight saving without the winglets and maintenance benefits. I believe that the D also had lower fuel capacity and different weights, but someone more knowledgeable than me may know better. Of course this all assumes that PMDG have a specific flight model reflecting the differences of the D. If not then it'll fly like a standard -400 in the sim anyway.

My apologies if it's an inconvenience that the site is down. Unfortunately at the moment I'm having to spend time lifting floors and working on a house rather than looking at a screen. I think my PC's are getting withdrawal symptoms. In the meantime for anyone who has airlinerperformance files please keep using and enjoying them, but I would ask that you do not (re-)distribute them. Cheers Jon

If memory serves the 550 is a recofigured 700. Revising (reducing) 700 weights and seat capacity etc should work.

Thanks Gentlemen. It's over so quickly! Phil are you back in the freezing north? B767-200 engine variants for the Flightfactor uploaded now. Although said to be -200ER by FF, the weights in the EFB are representative of a standard aircraft, so I've gone with lower numbers to match the EFB. As with all these you can edit payload options, weights and fuel figures to match your own flight model or airline preferences within PFPX in any case.

Merry Christmas folks. A couple of presents up at airlinerperformance.net ahead of the big day. Profiles for the newly-released A321 are uploaded and the first variant for the Flightfactor 767, the -300ER with RR engines is also up. These have CI data for climb, cruise and descent - interestingly looking at Twitch streamers no one ever seems to use CI on climb or descent. More 767s to follow. Also with the Milviz 350 out this week I've written a file for that (temporarily) linked here KA350i. I've fudged the perf at low weights so would be interested if anyone with that aircraft wants to try it and let me have any feedback. Once I know it's OK I'll put it on the site and remove the link here. Cheers!

Well you found me Loic 😉 No promise on how long, but if I can find a few hours this weekend, I'll run up a profile. Cheers Jon

Folks, profiles are built, but I've had a computer issue which will cause some delay. That's just about resolved, so hopefully files will be uploaded to airlinerperformance in the next few days once I've done a bit of testing. Thanks @AirbusCG for the polite and considered post there, and @donkey for the website check!

Apologies folks. As I was running numbers for the DC-10-10 I saw the DC-10-30 hold fuel flows were incorrect (the 10 has only 3 engines, not 4 . Correct file v1.10 now uploaded.

Hehe! New DC-10-30 and updated 747-400ER now uploaded. If anybody with the Aerosoft DC8 can please post the appropriate weights for the aircraft I'll finish off that profile.

Hi Phil, I've done 90% of the work on a DC8-50 profile, and if I can have all the weights for the Aerosoft model I can finish it. And I have completed a new DC10-30 profile, just haven't published it yet. Cheers Jon
