The cellphone 27 approach into Helena | Air Facts Journal
At 30 miles east of LWT, as I pressed the push-to-talk button to report our position, all the lights on the panel went dark. I reached for the avionics toggle switch. It was very hot and the switch showed no resistance when I moved it up or down.

Using 911 to Get Better Cellular Service from the Air
Here's an interesting article that talks about using a cell phone in the air to get clearance to fly an ILS into Helena, MT. What really intrigued me was that the pilot dialed 911, and felt that the signal was louder and clearer than when he tried to dial a number on the phone. He pointed out something I hadn't thought about, which is that the FCC requires all carriers to forward 911 calls, regardless of whether a caller subscribes to their carrier. So as the writer said, "our call to 9-1-1 was picked up by the nearest tower, not the nearest tower of my brother’s carrier." Good information to know if you're in a remote area and not getting good service from your wireless provider!
