GNX reversal heading shows inbound heading

[RobertGary1]

Just installed this GNX 375. It’s an amazing unit. Most of my Garmin time has been jn the G1000 is it’s interesting to see the differences. In this case notice that the dtk shows the outbound leg heading. As a result my hsi shows the pointer at 221 but the 375 told me to initiate the turn to 020 for the reversal. I see the same in a hold. The hsi and the dtx on the 375 shows the inboundheading even when telling me to turn for the hold. Have others seen this?

Gary,

This is standard Garmin behavior if I understand the scenario, and its look like your on a PT outbound or more properly a Hold in Lieu of Procedure turn at STNGR and your outbound on a Tear Drop entry? Your on a heading of 12 degrees and  Garmin has already updated the DTK to the inbound course of 221. It doesn't appear to me to be showing the outbound leg heading (unless you are referring to your TRK) but the DTK is on the inbound course of 221. Garmin annunciates what headings to turn, such "Tear Drop entry" and "Turn Left heading xx" (to say turn left 30 degrees for the TD) but the DTK is either the outbound on inbound depending on what kind of PT it is.

Its strange that it anunicates ("turn 020") for the PT but the HSI still shows the inbound heading (220).

Robert (sorry I miss typed Gary above!), its the way Garmin treats headings differently than tracks. It only changes DTK for actual track changes. On the hold, just as if you were flying a hold manually in OBS mode you would (or should) always keep the DTK on the inbound course. Garmin just annunciates headings changes to guide you around. The G1000 does the same.

hey @steingar did you see this one?

@kortopates I realized why this issue seems new to me even though I've been flying various forms of G1000's for a decade. This is the first Garmin set up I've flown without a flight director. Normally the flight director walks you though the hold.

Dear me I missed that.  What sharp eyes you have.  The folks in charge of that airspace must be discerning as can be.
