Airframe/Engine Time
I am pondering developing an inexpensive, resettable, total airframe/engine digital elapsed time meter. Powered from on board batteries, draws about 3 ma, but only while 'on'.... weighs about 10 grams, plugs into any "Y" in the system, and reads continuous total "on time" to tenths of an hour.
Couple of questions for ya'll.....First, anyone think this would be of any benefit to help manage engine run time, airframe, battery usage times?
Second, if you think it would be a benefit, what would be the "ouch" price for such an accessory???

RE: Airframe/Engine Time
Fun concept but how is "on" time differentiated from engine "run" time? Price wise, based on what I see in RCU it would have to be targeted at a specific user group. The size of the aircraft flown by the target group would determine the "ouch" level.

Hobbs time or tach time? Full size airplanes used to be rented by either Hobbs time (time engine turned on to engine turned off at any speed) or at tach time (engine running at 2500 rpm) or cruise speed. I believe for most small aircraft, 2500 rpm was the standard flight cruising rpm.

RE: Airframe/Engine Time
In your note - it would be "Hobbs Time" (engine running, regardless of rpm).

RE: Airframe/Engine Time
Thank you, yes that is out there, but is engine running time only. Some folks may be interested in total airframe time to track other things, battery life, etc. Appreciate the link.

RE: Airframe/Engine Time
Well, that's close....the 42% project is based on current load/draw from the source. I'm asking about simple "time" of power on (or engine run). Similar but different??
