I would guess that one issue would be the public safety services all
seem to use FM (even Highway Patrol at 42 MHz) but aircraft tend to
use AM. (would anyone care to explain why?) So if your scanner doesn't
have an AM demodulator in it, the conversion would not be easy. 

Anyway, perhaps I got a defective one, but my RS scanner is MUCH less
sensitive than my new Uniden BC-205. I could never pick up Highway
Patrol with the RS but can do it easily with the Uniden. Plus I have
200 channels and 800 MHz coverage.
