Hello,
yesterday I had my first longhaul flight on the AAU2 747-8 (HND-FRA, ~14hrs real time). Noticed, that the FMC calculates the ETA fuel on the CRZ page wrong.
Are you using Developer Mode or made changes in it?
No
Have you disabled/removed all your mods and addons? If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the Community Support section.
Yes. Behavior noticed with mods enabled first, made a second test with all mods removed. Same result.
Which aircraft are you reporting an issue about? (Please also add the proper tag for it)
Boeing 747-8 after AAU2
Brief description of the issue:
Despite having 161.6t fuel in the tanks, which is enough for enroute+alternative+reserve on my route RJTT-EDDF, the FMC calculates -24.7t as ETA fuel. The longer the flight goes, the more the value shifts to 0 and afterwards to positives values with only the very final phase of the flight having a somewhat accurate ETA fuel displayed (screenshot 1).
Tested this on another random flight KFJK-EDDF, the issue is the same. However, it is very noticeable, that changing the cruise alt before the flight significantly changes the ETA values (screenshots 2 to 4).
On a shorter flight KJFK-KMIA the value seems somewhat realistic, at least with a high cruising altitude (screenshot 5).
Provide Screenshot(s)/video(s) of the issue encountered:
Detailed steps to reproduce the issue encountered:
Plan a long haul flight (something with 7 or more flight hours), enter a plausible route and flight level and enter some plausible weight and fuel values (i.e. from Simbrief) and check the VNAV CRZ page.
PC specs and/or peripheral set up if relevant:
