Is Carenado AT 72 FMS better than the AT 42 one?
Looking at videos, it appears that AT 72 FMS is more complete (exemple: support airways entries instead of only waipoints)
Does it has the same problem that pilot should enter the plan as follow:
Departure
Approach
Arrival
Enroute (airways/waipoints)
to avoid unnecessary problems.
In a word, is AT 72 FMS better and if it is the case, why didn't they retrofitted it to the ATR 42
