Hello all,
I'm thinking of building an audio annunciator kind of like the P2 but modern and better (theirs was designed in the mid-90s). Would there be any interest in this kind of thing? It would annunciate:
* Overspeed
* Underspeed (e.g. climbing at < Vx, too slow on base to final, etc)
* An analog "slow horn" increasing in volume as you get closer to stall speed (say, Vs to Vs+10kts)
* Low oil pressure
* Low vacuum (for gyros, etc)
* Hobbs output to track time in service instead of tach time (which gets you lower hours for longer overhaul intervals)
The underspeed and graduated stall warnings are the most useful I think. Stall horns on most aircraft tell you when you're already in a stall, which is just a bit too late in most cases when you're really in a dangerous spot (e.g. base to final turns).
All these speeds would have parameters you could set via USB, enable/disable them, etc.
It would be designed to DO-160 and DO-254 standards for possible later STC certification, so it won't be a bare PCB with ribbon cable, etc.
Any thoughts? Do you guys/gals see a place for this in the experimental market?
Thanks,
Ray
