A directional gyro (a real one) should be reset every 20 minutes or so.
Our digital simulation of one might last that long.
The controlling software would plot the output history of every sensor.
It would then speculate by trends and project your future flight path.
The problem is if you lose vertical reference, your displays will be in
error.
IMHO
If you are:
indicating no rotational accelerations about your rate sensors and
your GPS log indicates no recent history of climb or dive or heading change
and
your pendulum device is not tilted then
your artificial horizon display should indicate straight, level and upright
flight.
And it should reset.
By tying all of these inputs into a set of algore rythms, the heads-down
display would remain correctly referenced.
I just graduated w/ AS in Computer Information Sciences.
I'm learning Visual Basic now and it seems like the right language to write
this kind of program in.
If there are any propeller heads who wish to collaborate on an open design
for engine and flight instrumentation and a navigational moving map program,
please make remarks here for now.
Bill Gates can do it; so can I?
