Strange hand-off problem

Recommended Posts

Last night, on a flight from SLC to LAS (Salt Lake City to Las Vegas), I had an interesting problem while being handed from one controller to another.I had just executed a go-around, and the tower handed me back to approach control, as expected, after I reported the missed approach. Approach gave me some instructions, asked for my intentions, and I asked for vectors. He then handed me off to another approach frequency. When I pressed 1 to acknowledge and contact, I heard what sounded like DTMF tones (like from a telephone), and the Radar Contact window briefly displayed "N/A". I thought this was strange, but I just kept flying to see what would happen. My pilot voice never called to acknowledge the handoff, and soon the approach controller came back: "American 104, I say again, contact approach on..." This time, there was no "acknowledge and contact" option. Instead, option 1 was:1- Approach on 11350I'm typing that frequency is from memory; it's probably wrong. But what's important to note is that the frequency that was displayed was NOT the one I was being handed off to. It's likely that was the frequency I was currently on. And when I pressed "1", I just got those tones and the "N/A" again.I was able to solve it by manually tuning my COM1 radio to the frequency that was displayed on the menu (ie, NOT the one I was supposedly being handed to) and then selecting that "1- Approach on 11350" option. When I did that, my pilot voice came on and said, "Approach, American 104 is with you at one zero thousand..." and all was well.Strange.

I will certainly do that if I get a chance. I have a feeling, though, that this is one of those fluke things that won't be reproduceable.I guess I was hoping someone would chime in and say, "Oh, the 'N/A' message means x, and you just need to do y to fix it!"
