Not a number error for time and distance on CRZ and PROG page

Recommended Posts


I've noticed an error today on my way from LYBE to EGLL (not the first time flying this route btw).

FMC is throwing NAN for time and distance to T/D and on the PROG page as well. Latest version of XPL (11.52) and latest version of the aircraft as well as the latest AIRAC.

Thanks for the report - interesting. I have never seen that before!

While the PROG page is still very much WIP, the distance to the top of descent on the cruise page normally works well.

I am very confident that this will not happen after the VNAV rewrite (which is currently on hold due to the horrible weather in Texas).

Cheers, Jan
