Re: [Fwd: Re: brake/rudder]
I am picturing a pressure sensor screwed in line on the master cylinders
that can be calibrated to the static brake pressure after bleeding. Then
any change +- some variance produces current that drives a small piezo
speaker in the panel with a unique sound (different from stall warning
sound) that allows pilot to back off the pedals. Can anyone with an
electronic background concur? Could this be made from off-the shelf
electronics components available from Digi-Key, etc.

I humbly defer to checked out Velocity Pilots and builders who are at
and beyond the rudder/brake assembly point because I could be totally
full of beans), but instead of a light, which I'd rather not be looking
for during a landing, what about adding a spring on the brake push block
What I'm looking for is the "feel" that I've engaged my brakes as I go
past full rudder deflection.
I understand that as airspeed goes up so does rudder pressure. As long
as rudder pressure at to/Lndng speeds is a lot less than that at cruise,
the BRAKE spring should cause noticeably greater pressure, giving us
mechanical feedback or "feel" that we're not justing moving a rudder
I haven't disassembled our master/brake cylinders, but for cars
there's springs inside the Master, and/or return springs inside drums
and/or behind the pedal that do 2 things: 1) insure brakes are OFF when
pedal pressure is removed, 2) and give us feedback thru our legs so we
know how hard we're on the pedal.
Would that work ?
