Help about AP disconnection

Post by Matthieu-C » Sat Apr 18, 2020 5:22 pm

In the manual, it is indicated for AP/Trim: DEPRESS TO 1ST LEVEL and DEPRESS TO 2ND LEVEL.
I thought it meant that I had to do a short press or a long press on the Autopilot Disconnect Switch on the yoke. But I'm not sure as for example, I never see "Red [TRIM] .... ILLUMINATED (PFD)".

Any idea? Thanks!

Question related to that: on the Premier 1 disconnecting the AP also kills the YP so they use the trim button to disconnect the AP as the YD would stay on.

On this KingAir the YD stays on. I don’t know if this is a general PL21 thing or if the Premier1 and the KingAir differ in that regard.

Hi,
Pressing the red button once disconnects the AP, pressing the second time disconnects YD.
Also if AP is auto disconnected, pressing the button will cancel the alarm.
