I wanted to follow up on what I wrote in Post #24 of this thread.... We figured out what I was missing when programming the GPS.
Before we started the engine on today's training hop, we put into practice what I wrote about inputting ALL of the flight plans we needed, including the approaches we were going to do. And then worked on figuring out how to get the GPS to sequence from our current location (the hangar) to the initial point (the LOM for the
ILS18 at KDTO).
If you want to follow along, the GPS I have is the CNX80/480. I repeated what I was doing wrong in the air (making sure KDTO was the destination, then going to the PROC page to select the approach and "entry"). I had it loaded, because it would show as a saved list of waypoints, but each time I tried to press the >D> (direct) button to select DTi, it wouldn't let me. I would be shown a screen confirming I wanted to go direct to the KDTO.
"No, I want to go to the DTi, the outer marker."
The "aha!" moment was when my instructor asked what would happen if after loading in the approach way points, I pressed the EXEC (execute) key. This is the function that both saves the new or modified plan
and starts the sequence. I had been doing the steps that was only saving, not the ones that said "start the sequence". Now that I had EXECuted the flight plan, I was able to press the Direct button, scroll to DTi, and have the unit step through the full procedure.
So chalk this one up to learning about your equipment. Now I know what has to be done to get the approach into the plan, get the sequence running, and select where I'm starting the approach.
