Don't think this will apply to anyone here, but doing some digging on IFR instrument requirements.
You can have all the Cheltons or Dynons or other fancy electrics you want, but you are still required to have;
From 91.205 (d)
Gyroscopic rate of turn indicator
Slip-skid indicator
Sensitive altimeter adjustable for barometric pressure
Gyroscopic pitch and bank indicator (artificial horizon)
Gyroscopic direction indicator (directional gyro or equivalent)
Any body know any different?
