B777 legs page - building a waypoint
Wanted to build a point 100 nm before 69N060W. That waypoint was L line selected into the scratchpad.
The following were rejected :
69N060W-100
69N060W/-100
I believe - but cannot be 100% sure - that we were more than 100 nm away from 69N060W.
What is the correct format ?
In which manual can I find the correct format ? FCTM ?
