This would result in chaos among those aircraft aloft. More and more pilots are using GPS as their sole navigational device.

GPS was supposed to have been a add-on nav device. Predictably, it has become the sole nav device for most pilots.

Fortunately, checkrides include dead panels and thus make you still be somewhat aware of your position. I lost my tray except for one old sole Narco Nav11 standalone once. I kept having to switch back and forth on stations to get a fix. It was total recall from twenty five years ago, but it comes right back.

What did pilots use, say, fifty years ago? Are they not still trained in a more basic navigation system?

I learned to fly before it was so common. I got lost once over western Tennessee during some high winds and found out why a lot of old buildings have the name of the town on their roofs. Thank God for that and ADF. Unfortunately TVA transmission lines play hell with ADF.
