maxro 7 Posted September 3, 2018 Share Posted September 3, 2018 Hello, I am having problems with the PFPX template of the A318 and A319. I get an ok looking fuel number using PFPX, and when I put input the GCD, and all the rest I get very weird fuel weights. Once, I was flying BAW1B, i.e. EINN to KJFK and I ran out of fuel near BIKF. Are there any plans of Aerosoft making a PFPX template that shows the same numbers and the same numbers in the sim selection view? I've tried making one, but I am a beginner :/.

flying_David 5 Posted September 4, 2018 Share Posted September 4, 2018 I assume, you used the same settings for PFPX (Altitude, Taxi time, APU time etc.) ? The difference of about 200kg on trip fuel is not that much. The flight planner probably can not really consider route details, whereas PFPX could. At the end, you end up with only about 250kg difference on 4.4to (thats about 5%...) The difference on a longhaul flight with the A318 is probably more interesting.. What were your settings there?

maxro 7 Posted September 4, 2018 Author Share Posted September 4, 2018 I have attached the fuel load page and the route. This was back in July and the wind wasn't calculated.

flying_David 5 Posted September 4, 2018 Share Posted September 4, 2018 Well, that seems to be a legit OFP.. I don't have PFPX to hand now, 15to of fuel could be ok.. What is the problem now or the question? Here is what I do: I either plan with PFPX all the weights OR with the fuel planner - not with both, because both have slightly different calculations going on, so I could never make them equal. If I plan with PFPX the weights & fuel, I will insert that data into the fuel planner, in terms of fuel and payload. I would than try to meet the correct weights as good as possible and then generate a loadsheet. This loadsheet is than the one that I load in the FMGC3 That's it, works fine for me and I never ran out of fuel. Maybe you had a typo or a unit problem (lbs/kg/liters) Link to comment Share on other sites More sharing options...

This loadsheet is than the one that I load in the FMGC3 If you want to use fuel planner ONLY than fill the according fields and DON'T care about PFPX calculations.. That's it and you're fine. Anyway, having a few 100kgs of in fuel or weights is daily business in real aviation as well. You will NEVER have weights or fuel 100% correct according to the OFP. If you run out of fuel because you have 300kgs to low on fuel (as shown in your screenshot in the first post), than you have a GENERAL problem in you calculation. That's why you add reserves, contingency fuel etc. I'm pretty sure, that you can conduct the flight either with 4100kg or 4400 kg of fuel from EDDF to EHAM without problems. There will always be slight differences. If you doubt a value, re-calculate it by hand or add more fuel. That's what they do in real life as well.

Deputy Sheriffs Tom A320 4915 Posted September 4, 2018 Deputy Sheriffs Share Posted September 4, 2018 Please keep in mind that the fuel planner is not a complete flight planner and therefore not aware of the route and the weather. That will of course lead to differences in the results of both tools. Link to comment Share on other sites More sharing options...

flying_David 5 Posted September 5, 2018 Share Posted September 5, 2018 vor 14 Stunden , maxro sagte: Thank you @griestraum ! Any ideas on why I ran out of fuel? Well, as I mentioned before, maybe a unit problem, kg/lbs/liters? Or you took a different route than planned? Different altitudes or flown longer on lower altitudes despite differently calculated? Maybe it was a planning error ... There are many reasons, it's hard to guess remotely,.. I never ran out of fuel with PFPX calcluations. I suggest, that you plan again the route, fly it again and then report everything here with screenshots, that we can see it. If I have time today, I will try to recalculate it at home.

maxro 7 Posted September 5, 2018 Author Share Posted September 5, 2018 Thank you, @griestraum the community on this has (almost) always been helpful. I will try and fly BAW1B this weekend. Link to comment Share on other sites More sharing options...
maxro 7 Posted September 9, 2018 Author Share Posted September 9, 2018 I don't get it: I planned AAL5708 on PFPX. In the screenshot you'll see the bigger difference. And I do not know how to calculate it by hand (that's why I use PFPX). Please login to display this image. Link to comment Share on other sites More sharing options...
Emi 5161 Posted September 9, 2018 Share Posted September 9, 2018 How about weather, weights, route distance, aircraft setup? Are you sure everything is actually set correctly in PFPX or in our Planner? Link to comment Share on other sites More sharing options...
Jockos 5 Posted September 18, 2018 Share Posted September 18, 2018 Is it planned that PFPX figures can be transferred into the AS Fuel Planner? Cheers Jock Link to comment Share on other sites More sharing options...

Cheers Jock No, this is not planned. Ps.: Please do not hijack other threads, just open your own one if you have a question which is not covered in another thread already.
