As I work through the details of and try out various scenarios with the A/P CMD and CWS modes, I ended-up disengaging the A/P completely (manual controls). When I attempt to re-engage the A/P either in CWS or CMD in flight, it will not do it. Can someone tell me what conditions prevent the A/P from engaging. The A/C is trimmed and have level flight. Thanks,Zach

Is the autothrottle engaged ?

Yes.

I had an issue (I can’t remember the reason behind it) when after I had to disengage the auto pilot, after I reengaged it I had to re enter the cruise altitude under the ‘CRZ’ button on the FMC... That one foxed me a little... Kimberly.

CRZ looks good. Tried it again several times. I can't seem to be able to re-engage the A/P in flight. Zach

What modes are you trying to engage?

Make sure your joystick is calibrated.

Have you pushed the disengage bar back up?It's under the CMD CWS AP Modes Buttons
