FM vs GPS position
Denis and others.
The first accident reports states the following:
"The first position message (AOC type message) was transmitted on 31 May at
22 h 39. On 1st June at 2 h 10 min 34, the last position received was latitude
+2.98° (North) and longitude -030.59° (West). The position transmitted was the
aircraft’s FM position which, in normal conditions, is close to the GPS position."
I am unsure how exact the FM position is compared to a "real" GPS position.
Could this explain the differences in assumed final position and current search area?
