Hi all Fellow Mono Pilots,
It seems strange that I was showing my wheels up warning device to Bob Hitc
hcock last weekend. He was saying that other people could be interested , b
ut 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 se
t to less than 65 Knots for landing, a proximity switch puts a +ve signal t
o the controller. With the wheel up a bright red led flashes. After 30 seco
nds 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 si
ren 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 anoth
er one. It works well, but installation requires a bit of patience to get i
t 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 kit
s. 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
