The D180 is an altimeter, ASI, artificial horizon, turn coordinator, compass, directional gyro, altitude encoder, EGT gauge, CHT gauge, tachometer, manifold pressure gauge, clock, fuel level gauge, and a whole bunch of other things all in one box. I'm sure we meet some TSO in there somewhere
Basically, we designed the EFIS and EMS while looking at the major TSO requirements, and we expect that they would meet them, but we make no guarantees about this.
