So say I have a flight plan in the GTN 750 with 5 airports as waypoints, ABCD and E.
I start at airport A and pass airport B. I now want to fly an RNAV approach at airport C. But when I go to procedures, the only RNAV approaches I can select are for airport E, the final destination of the flight plan. I also can’t activate the approach from the airport’s “waypoint info”.
Is there no way to fly an RNAV at one of the intermediary airports and then continue the flight plan?
I guess I’d need to do a “direct to” to the airport C RNAV, which kills the flight plan, and then, after landing, load the flight plan again (I think this is possible in the paid GTN 750)and delete the waypoints I’ve already covered? Or is there another way?
Any insights much appreciated, thanks!
ATC is somewhat limited. Since airport C is only a waypoint(?) but since you want to land at C, that becomes the flight’s destination. A new flight plan is needed when departing from C especially if a SID is used.
I’d like to file an IFR flight plan to fly to an airport using an ILS approach, perform a touch and go, fly out some distance, then return to the airport using a RNAV approach, doing another touch and go, fly out and and return using a VOR approach. There is no way to construct a flight plan having three IFR approaches to the airport.
The way the navigation system work is by defining a departure point and one arrival point. It does not matter if the route points are waypoints, VOR, or airports, for the system they are simply route points and the nav system will only offer you the option for loading procedures for the departure and arrival airports. This is not a GNT 750 independedt issue but a convention in all cerftified navigation systems. The same logic applies even to advanced FMS systems. One of the reasons for this is to prevent the human error of loading the arrival or approach of a different airport than the intended one. The Nav system will only allow you to load and arm the selected procedure to the airport that you have defined as arrival point.
If you want to make several landings along your route you would have to create a flight plan for each departure to destination. To make things easy you can also save the diferent routes as independent flight plans into the GPS so for instance you can have active first flight plan A to B but have stored and prepared to be used and recalled A to C or A to D or B to C this way you can easily replace the actual flight plan and recall the new flight plan already stored in your system and then the NAV system will offer you the option to load and arm the related arrivals and approached for the newly defined arrivalm airport.

Thanks, i thought this might be the case!
