Hi All,
I have over a thousand hours of retract time, but in a single pilot
operation I still wonder when my turn to leave the gear up will come.
So, with all that said I am becoming more interested in what systems I
can put in place to minimize a gear up landing. Once I got the
oportunity to get some time in an Airforce 3 axis simulator for a
KC135. One thing that really impressed me were the voice alerts at 50
and 30 feet generated from a radar altimeter.
While systems like this are getting beyond the scope of home builders,
I was wondering if anyone has had good experience with ultrasonic
based devices that can perhaps measure 10 feet off the ground.
I am thinking that taking inputs from manifold pressure, airspeed,
gear microswitches and some altitude input and feeding them into a
simple micro controller could generate a nice warning system.
With that said there are plenty of examples of two pilot operations
ignoring gear up warnings, but having an additonal system in my
aircraft would be nice.
I'd be interested in peoples input and ideas. If as a group we can
come up with an approach I would be prepared to build and program a
suitable micocontroller.
