Hello guys,
I tried like crazy to find in the FCOM where it says that the FMGS measures actual winds up to 200 Nm (Pegasus) and 100 Nm (Thales) ahead of the aircraft for predictions but I can't find it anywhere.
The only thing I found is : " The system calculates and displays predictions for all the waypoints.
It uses current wind to compute preditctions for the To waypoint, and uses predicted winds for computing all others"
Source: FCOM- Aircraft systems- Auto Flight- Flight management- Control and indicators- MCDU- Page description.
Bonus question: Do you know why sometimes the TOC prediction displayed on the ND is so inaccurate? Sometimes by like 30/40 nm even in the newer aircrafts..
Thank you for your help.
