I'm trying to get smart on the use of GPS in lieu of DME.
How do you actually (legally?) display distance to a tuned navaid? The only way I've figured out so far is to have it as the active waypoint in my GTN (basically, Direct To the navaid)...which means I can't also use the GTN with the approach I'm flying activated.
If it matters for this discussion, my GTN is interfaced to a SkyView Touch, which will show valid CDI data, but no distance info to the tuned navaid. I have to look over at the GTN for Distance to Waypoint.
For a practical example, take a look at KBOI VOR/DME or TACAN RWY 10L. I have the BOI VOR (113.3) tuned in the NAV radio with valid CDI info displayed on the EFIS. I arrive at HMISH, and would like to fly the 12 DME arc. If I have the approach active in the GTN, I don't have distance to the BOI VOR displayed anywhere--any distance info from the GTN is ALONG the arc to the next waypoint, not actual DME to the VOR. For that, I have to do some sort of Direct To and type in BOI, and therefore lose the active approach in the GTN.
Am I doing this wrong? Thanks for your time!
