I have been unable to get coupled VNAV to function at all in the TBM 930 since the AAU1 update. In its previous modded state w/the WT g3000 mod it gave an excellent indication of the descent rate and indicated the next step in altitude. It also indicated the TOD. None of this was coupled to the AP in that iteration so I was really looking forward to this update.
It's obvious that coupled VNAV is working for some. thecorporatepilotdad YT video on using VNAV for descent control in an ILS approach showed that it was operational, at least for him, so it must be something that I'm doing incorrectly? I have set up in the following manner:
Set the altitude of the FAF in the PFD
Verified that the proper procedure is loaded in the g3000 and the proper altitudes are assigned to each fix
Enabled VNAV in the GTC
Enabled VNAV in the AP
I get nothing. Sometimes a "PATH" indicator comes on in the PFD but no TOD appears on the MFD map now and the AP will not initiate (nor indicate) a descent. Any ideas?
