Perhaps I am used to NGX, but I was wondering why I can't program the FMC waypoints if I take off without a flight plan.
If you take off with no DEP/ARR set, you can't program the route anymore - you get the invalid operation message. If you try something like DIRECT->[some way point or airport], you can't do that either. If you go to Route -> divert to, it shows all the airport around you, but selecting one of the airport and clicking on divert now does not work either. So, once you are in the air, it seems that if you did not enter some sort of route into FMC, there's nothing you can do. Lets assume you had a situation where you had to reboot the flight computer during the flight, what then ? you can't enter your route or waypoints anymore? It seemed to have worked fine on NGX, but not on 777 (p3d 2.5) ... Is there a way ? has anyone managed to do that succesfully ?
Thanks.
