Trutrak and IFR Checkride / IPC?

[alaskan9974]

I know the Trutrak in certified installations has a 700’ agl limit and coupled approach limitation, can it be used legally prior the final approach fix using heading and altitude bugs, or even under GNSS?

I know the Trutrak in certified installations has a 700’ agl limit and coupled approach limitation, can it be used legally prior the final approach fix using heading and altitude bugs, or even under GNSS?

On my recent IFR check ride, I used my TruTrak (AeroCruze 100) for heading vectors and GPSS (with my Avidyne IFD 540). The DPE did not object.
