Hi, I'm very happy with the Learjet but I have a question about the autopilot. 

 

How can I set a preset the VSI or set an rate of climb ie. 4,000 fpm?

 

There is no manual for the autopilot and the autopilot does not have trim wheel.

 

Thank in advance.  

There is no preset with this autopilot. You trim the aircraft to the v/s you want then select v/s mode on the autopilot (provided you have the autopilot all properly engaged prior to selecting v/s mode). The v/s mode will hold the v/s that you are indicating at time of engagement
