Here is the expensive solution.... http://www.aircraftspruce.com/catalog/inpages/rca2600.php or http://www.aircraftspruce.com/catalog/inpages/sigmatek5000.php for an electric gyro
RC Allen seems to have the only TSO'ed digital Horizion that you can put straight in the shallow ercoupe panel without a venturi/vacum... The last time I checked, the Aspen did not have Erco/ALON/Forney on it's approved list, and the handfull of other solutions would cost nearly as much as the ercoupe airframe, and still needed an STC. I wouldn't throw out a good gyro to get one, but if you are going all-digital with GPS and moving maps, this will complete the panel, and should be approved. RC Allen had a prototype DG on display at Oshkosh whith a simular layout. I got one last, year before finding other higer priority items to repair. I'll post pictures when it's in. --- In [email protected], Syd Cohen <sydl...@...> wrote: > > Here is the list of required equipment for VFR day/night flying: > > To help remember 91.205(b) (VFR Day Instrument Requirements) we'll use A > TOMATO FLAMES.
