Sounds like a great idea Bryan.
I had always wanted to fit something similar but just havent had the
time to think it through - or get round to doing it.
I guess when it happens to you then it focuses the mind.
I would be interested in the details.
BTW how does the system recognise the aircraft is below 65 knots - ie:
where is the input taken from?

Hi all Fellow Mono Pilots,
It seems strange that I was showing my wheels up warning device to Bob
Hitchcock last weekend. He was saying that other people could be
interested , but I was not so sure. It seems that I may have been wrong!
I have developed a simple processor to control the system. With the
trim set to less than 65 Knots for landing, a proximity switch puts a
+ve signal to the controller. With the wheel up a bright red led
flashes. After 30 seconds of no further action a very loud intermitent
siren makes itself known. Normally you will have the wheel down within
the 30 seconds, so that the siren does not come on. The siren can be
temporarily overidden if required.
When the wheel is down and locked, a bright green led comes on, and
the red flasher goes off.
Having had my own wheels up experience I have no intentions of having
another one. It works well, but installation requires a bit of patience
to get it set up for the 65 knot speed. It weighs a few ounces, and you
need about 6 cubic inches of space behind the panel.
I have no ambitions to start large scale marketing of it, but if
sufficient people were to be interested I do have the resources to knock
out some kits. There are no approvals on the device, I don't even know
if it needs one since it is not attached to any part of the controls.
Regards to all.
Bryan
