OK I get the feeling nobody is going to guess

what I have in mind.

Absolutely the cheapest way to do an EFIS is use

voice synthesizing

technology.  No expensive LCD, LED or PDA at all.
Although bar graph LEDs are a very cheap way to

go but they do take

up space on the instrument panel and suck power.

Everybody that flies an airplane has a head set.

"Your EGT on rotor one is 1400 degrees."
"Your EGT on rotor two is 1450 degrees."
"Your coolant temp is 220 degrees."
"Your oil pressure is 80 psi."
"etc., etc., etc.."

You could push one of several buttons each with

different info on

the stick or on the instrument panel to get the

info when you

wanted it or allow the system to inform you when

something went

out of preset limits. If something started

changing too

fast it could warn you automatically.

It could also work as a stall warning.

"PUSH THE STICK YOU ARE GOING TO STALL!"
"PUSH THE STICK YOU ARE GOING TO STALL!"
"PUSH THE STICK YOU ARE GOING TO STALL!"


The possibilities are infinite. The cost and

panel space are minimal.

With a solid state gyro you could have your own

personal on-board flight

instructor.  I can hear it now...
"PULL UP YOU'RE TOO LOW!  PAY ATTENTION!"
"NO, YOU PULLED UP TOO MUCH, NOW YOU'RE TOO HIGH!"
"YOU'RE TOO SLOW, YOU'RE GOING TO STALL!"
"WATCH FOR TRAFFIC!"
"#&%*#@*&%....

Are we getting creative now or what? :-)>

Hey Gang,

Being from the old school and I do mean old!..

Paul the problem with audio. The FAA requires us to
have one oil pressure direct reading instrument for
each engine installed, same for temp, tach and gas
gauge etc: and on and on.

I like to see as well as hear. Heck one of my two
senses could just quit anytime!..ouch  but both visual
and audio together would be fantastic. I like a
cluttered panel it makes my walter mitty come out. (I
drive a varieze). Now if someone would come up with a
"heads up display" at a reasonable price!!..hummm how
bout a back lighted LCD laid on it's back with a
polished piece of plexi set at a angle for a
reflector?..

John, frozen in KY.

Does that FAA rule apply to experimental airplanes?
