Sorry, it is the 737-100 and 200 series.
thanks

I saw you asked why you can post a new topic in the 737 forum, so I have been preparing a new response. And here it is:
1. ELEV mode ENGAGED - You adjust the ascent/descent rate using your joystick/yoke/controller. Descent is more sensitive than the ascent. For descent, make small movements or the descent can easily reach -4000 fpm (I push down until it gets to -2000/-2500, then pull up o bring it to a slower descent.
2. ELEV mode ENGAGED - You turn the knob to Altitude Hold (it's on the right side of the A/P). See image below.
3. AIL mode ENGAGED - When the HDG switch is in the centre, it is controlled using the CWS mode. If you level the wings, the aircraft will fly straight ahead. Bank to the left/right (more than 5
o) and the A/P will hold the bank. You can use Heading Hold (switch down). Then move the heading bug to the heading you want to fly. See image below.
4. There is no Auto Throttle! It is an older aircraft and is controlled by the pilot/co-pilot throttle inputs, so YOU control the airspeed.
NOTE: There is a trick that you can do so that the 737 will adhere to the SPEED BUG. The default Keyboard Command for
Autopilot airspeed hold (on/off) is
CTRL+R and the
autothrottle_available=1 is already available in the [Aautopilot] section of the aircraft.cfg, as is the
autothrottle_arming_required=1. This means that once you arm the A/T, you can then use the A/T to control the speed. The CS 737 does not have an A/T ARM switch, so I set mine to
autothrottle_arming_required=0 and all I need to do is press CTRL+R, and the 737 will (1)set the speed bug to the current airspeed, (2)turn the A/T on, and (3) will obey the Speed Bug setting, so you can change the speed to suit yourself.
I found the response of the A/T too slow. This is the default
max_throttle_rate=0.10 setting, but you can change it to improve how fast it responds to changes. I had changed it, but I can't remember the settings because I went back to not using it (I felt like I was cheating).
