Go Around behavior with GA button

[Sweet19blue]

Hi,

Practising go around using the GA button, I keep noticing that the Autopilot does not disconnect when pushing the button.

The TBM 850 G1000 manual says it should disconnect.

Also I saw G1000 video where FPL sync got suspended with a SUSP soft key during the go around. Pilot have to push SUSP softkey to re sync the FPL. Do not know if it should apply to the TBM. There is not much infos about GA in the TBM 850 G 1000 manual.

Best regards,

Pierre

I don't know if this is the reason of your issue : for go around, you have to set a button or key to "autopilot take-off go around". It is not the same one as the TOGA button, used with an autothrottle. I confirm that the SUSP soft key is available after GA on the PFD.

Yes, it is the function that I have assigned...and your AP disengage when pushing GA button?

Maybe it is due to the autopilot engagement. What function should I assigned to simulate the AP push button on the MCP?

In the joystick xp menu, I assigned a button to the function tbm900/ap/autopilot command master on/off.

I always disengage the AP before landing and, eventually, perform a GA... So I did not test that.

then press the TOGA button and the FD will set a predefined pitch you should follow and after established gear and flaps press the SUSP softkey and NAV. Then you will follow the missed part of the FP.

TOGA button will set TO on the ground and GA in flight. Be aware the SUSP will only be available after minimums WP (I think)

Can’t get SUSP to trigger in the TBM (or should I say XP LR1000). Pressing TOGA before or at minima does not disengage AP for sure. After pushing GA, just pressing NAV exits the lateral GA mode and the GPS follows Go Around FPL.
