One for Manfred I think.. nav radios.
I've been trying to get the AP to follow a nav track rather than blindly letting it do it's own thing with a planned flight and GPS selected. I've noted on previous flights that the localizer/distance gauge often doesn't show TO.. only FROM. Further tests flying from VOR to VOR using nav1 show this still to be the case. For example.. I can setup on the runway at Culdrose, take-off and tune nav1 to the Lands End VOR. On this occasion (always) the FROM/TO arrow flags TO which is correct. However.. flying past the VOR.. the localizer/distance gauge remains at TO and doesn't flip to FROM as you overfly. Tuning to further VOR's on nav1 invariably flags FROM not TO though tuning to an ILS.. it will flag TO. It will not, however, flag FROM if you overfly.
The RMI consistently finds the VOR and points to it. It will also swing as you overfly.. eventually pointing 180 from where it was.
With all this said.. I can't see how you can successfully fly nav to nav using radios.. I certainly can't after days of trying. IF there was a way to switch radios.. eg, use nav1 for ILS and nav2 for navigation using the RMI.. you'd be able to do it. Is nav1 assuming an OBS control to select a radial? I don't know. For sure.. a control switch to select nav1/nav2 active-inactive would solve the problem and by changing 1, 0 to 1, 1 in the cfg would allow you to flit painlessly from one VOR to the next using the nav2 radio (or nav1 were it not slaved to the ILS/distance gauge).
Or.. perhaps I'm barking up the wrong forest
I'm not sure what's more frustrating.. that I can't get it to work or the fact I'll probably never use it if it does!
