There is some coating on the canopy of newer tactical aircraft that doesn't allow the use of hand held GPS units.

I used to use one all the time flying F-14A's because our INS was so bad.

That as bad as when F-15 pilots were using radar detectors - from Radio Shack - in the cockpit.

Forget what the deal was, certain band, etc. I do know that I found a few and had to stop by OP's, "who owes me beer?" lol
