Autopilot question

[cessnalover858]

Hello guys,
first: The C182 is amazing! Great work A2A!!!

First question:
Is it possible to turn off the autopilot? As you can't pull the circuit breaker, and I want to shut it down without turning off the master switch, I don't know how.

Second question:
Can I somehow change the "BARO" setting on the autopilot from INCH to QNH?

Thanks in advance,
Cheers

1) Not exactly sure if you mean turn it of electrically (instead of disconnecting it using appropriate switch)? Then I presume no, though you can kill the avionics buses using avionics master..

2) Press and hold the baro button for two seconds. I haven't tested but I think it's modeled.

I wondered about turning the AP off because I think its mentioned in a checklist in the manual (but perhaps they just mean to ensure that its not activated).

Apart from that, wouldn't it normally have a switch to turn it off anyway like most of the other avionics do?

Hi Esa,
thanks for your answer. Will try this out.

No, not necessarily. The KAP 140 used here works as an altitude alerter even if the autopilot itself is turned off. It's likely part of checklists because it is rather important to make sure the autopilot is not inadvertently switched on or armed, airplanes have been flown into ground due to lesser distractions. It doesn't matter if it is electrically powered through the avionics master. Pressing the disconnect switch once to be sure is more than enough normally. In many autopilots the annunciations are much less noticeable than in KAP 140.

There is an autopilot disconnect button on the yoke. I use the A2A input configurator to assign this to a joystick button. (Of course, it still won't turn the autopilot power supply off.)

I did that once. I don't remember which plane or even which simulator but as soon as I picked up speed on the runway the plane seemed to try to achieve a 1000 fpm climb rate. I can see that in a real aircraft particularly this is something you'd probably want to avoid.

Thanks for the tip about the 'disconnect' button. It sounds obvious but hadn't occurred to me, I normally just glance at it or assume.

I know how to disengage the autopilot I only wanted to disconnect it from the power source.
Can anybody confirm, that the circuit breakers are different ones than in the C172? In the 172 you can pull the circuit breaker for the Autopilot.
When I flew it I had to push it in at least

Afaik, the white C.B.s on the panel in the C172 & C182 are the same style i.e. they are "push to reset" only. Neither are the "push-pull" type breaker.
