A "chopper" will work with both, but 2 separate ones would likely work
better.


You'll have all sorts of fun with radio interference...

The majority of dash lamp dimmers in automotive apps today are
choppers. Properly filtered, they are quiet - but you DO have to do it
right.


You're right, but there's one difference with automotive installations. The
radio's are usually FM, which is a lot less susceptible to interference.
Aircraft radios are AM and it takes a lot less spurious signal to upset
them. If you want to try it, prepare for good ground path and shielded
wires.
