sunake Posted January 21, 2022 Report Posted January 21, 2022 Hey guys, I would just like to know if I should be clearing out the fms calculated fuel on the per init page 1 from time to time during the cruise to force it to update. I noticed it will deviate from sensed fuel and giving me inaccurate fuel predictions.
Pils Posted January 21, 2022 Report Posted January 21, 2022 No, if you’re going to do it, do it when on the ground during preflight.
sunake Posted January 21, 2022 Author Report Posted January 21, 2022 Okay so in flight I just have to live with the inaccurate fuel predictions or can something be done about that?
ois650 Posted January 28, 2022 Report Posted January 28, 2022 Once you select sensed fuel your in-flight total should remain accurate.
sunake Posted January 28, 2022 Author Report Posted January 28, 2022 By selecting sensed you mean clearing out the calculated value on the perf page or are you talking about the "sensed/predicted" option I have seen somewhere else in the fms?
ois650 Posted January 28, 2022 Report Posted January 28, 2022 I meant clearing the calculated value in PERF
