Hello Chums... :)...!

Every now and again I forget how I did things in the past, (including procreation*) so here we go...

On my Bendix-King Radio Stack, etc, Autopilot (Ap) also has Heading (Hdg) and Altitude (Alt) selection buttons.
This works fine, when I want to engage all of them, but sometimes I wish to select Autopilot (Ap)and maintain Altitude (Alt) but leave Heading (Hdg) switched off, so that I can manually vary my route.
On some of my aircraft, BOTH Heading and Altitude are fixed as soon as I select Autopilot (Ap) even with Heading (Hdg) button switched off!

I suspect that there may be an entry somewhere in the Aircraft.cfg file, where the "Autopilot" preference options, "Heading and Altitude", can be pre selected?

..... ;D....!

Paul, in the [autopilot] section, there are a couple of edits you can do: (works in both FS9 and FSX) 

Either add/edit these 2 lines-

use_no_default_pitch=1      Setting this flag to 1 will cause the default pitch mode to be "None". It will actually set the variable default_pitch_mode to zero, so that there is no default pitch mode when the autopilot logic is activated.
The preferred method is to tset the default_pitch_mode directly. 

use_no_default_bank=1       Setting this flag to 1 will cause the default bank mode to be "None". It will actually set the variable default_bank_mode to zero, so that there is no default bank mode when the autopilot logic is activated.
The preferred method is to tset the default_bank_mode directly.

Or these 2-

default_pitch_mode=      This determines the default pitch mode when the autopilot logic is turned on.
0 = None
1 = Pitch Hold (current pitch angle)
2 = Altitude Hold (current altitude)
If no value is set, Pitch Hold will be the default.

default_bank_mode=     This determines the default bank mode when the autopilot logic is turned on.
0 = None
1 = Wing Level Hold
2 = Heading Hold (current heading).
If no value is set, Wing Level Hold will be the default.

The other option when flying is to turn HDG on then off which will disengage the default wing leveler.

You can download the FS2004 Aircraft Container SDK here-http://www.fsdeveloper.com/forum/downloads.php?do=cat&id=10-which contains the 'how to' for configuring the aircraft.cfg file.    

Dave, me old Chum... ;)...!

I think you might have cracked it with your suggestion!...>>>

"The other option when flying is to turn HDG on then off which will disengage the default wing leveler."

.... :D....!

Selecting at what point to toggle the Heading (Hdg) button on or off, allows me to choose whether I wish the Autopilot, or me, to take control of the Heading, and still maintain Altitude (Alt)!
(Its the Wing Leveller bit!)

It seems to work... [smiley=2vrolijk_08.gif]...!

Just tried it out on my little Cessna 150 Aerobat, with its full Bendix-King radio stack...

Wonderful!

Ta Dave!.. [smiley=thumbsup.gif]...!

Paul..."Heading" your way, with a big bag of chocolate cookies!... ;D...!

Another option is to press "control-v" after starting the autopilot which will turn the wing leveler off direct without going through the  heading bit.

Many thanks, Chums!

Loads of good ideas there!... :)...!

Paul....Fully Automated... 8-)...!

Paul...still need help with procreation? My wife and I could write a manual for you.  ;D Best regards, Jeremy

It gets me into trouble!... :-[...!

Paul.... ;D... ;D...!

I just go Fly-fishing instead, now... :)...!

;D Nice! Nothing better than sitting around with mates and bragging about the size of your fish!  ;D ;D
