Sure, but that doesn't take care of INADVERTENT opening of the
spoilers. Examples: weak geometric lock + some turbulence;
Dual-command + some confusion in the other seat; You can probably

Speaking of simple warning devices:
How about a simple hookup to a horn which is activated
when the
airbrakes are opened while the towhook is engaged (i.e.

during tow)?
A microswitch on the airbrake levers would be the no-brainer
part.
What about the towhook? Magnetic sensor? where? How?


Other ideas?


how about the last 'B' in CB-SIFT-CB i've always found
it to be a no-brainer personally, and its completely
free! Usually accompanied by the guy who attaches the
towrope/cable saying that phrase 'brakes closed and
locked?'
