KAP140 question

[taguilo]

Hi,

I have some tech questions regarding Bendix King KAP 140 autopilot:

-APR mode, LOC and GS captured, is it possible to cancel GS by selecting other pitch mode (ALT/VS) or it is necessary to first turn off the autopilot?

-Same as above, is it possible to cancel APR by selecting other roll mode?

- Does pushing NAV once NAV is armed or captured revert to HDG mode? And the same for APR/REV?

-If red P flag turns on, it means pitch modes are inoperative. Does it show dashes on pitch mode/armed mode positions?

-If unit with Altitude Preselect option, which is the altitude displayed when autopilot is first powered, and after PFT test?

Many thanks.

I've got the manual for this autopilot in PDF. If you send me your email address in a PM, I'll forward it to you.

Point is I don't have a flight instructor. Actually I am building a KAP140 unit simulator so the reason for such specific questions.

Thank you. I do have BK official pilot manual, Installation manual, etc. But the info I am asking for is not present there, I guess it is really a pilot observation matter.
I do fly C172 and similar aircraft in rl but none of them have any kind of autopilot, hands flying only!
