Hello!
We were flying to our destination a few days ago when during cruise, I noticed there’s a discrepancy of up to 1,000 ft between REC MAX on the PROG page of both of our MCDU. AP1 was controlling the ac at that time
I checked my box and it shows a lower figure than the other. We were one hour in cruise. How come we are in a discrepancy? Same with our OPT FL.
ETA on the box, as well, was off between each other by up to 3-6 minutes. Clock was set to GPS.
I understand the FMGC computes the REC MAX by the ac gw and temp.
Checked fcom, fctm but with no luck.
Thanks to those who might be able to shed a light
