-==== General information ====+The basic autopilot is found in the [[aircraft:cessna_172|Cessna 172 SP]] and the [[aircraft:baron_58|Baron 58]] aircraft. It features a bank and heading hold, turn to selected heading, navigation follow, pitch hold, vertical speed hold, altitude hold and approach modes as well an altitude pre-select function. 
 +===== Engagement Conditions =====
      
 The autopilot can stabilize the heading, airspeed, altitude as well as the vertical speed. The autopilot cannot be switched on/off and will disengage when one of the following limits is exceeded: The autopilot can stabilize the heading, airspeed, altitude as well as the vertical speed.

 The approach mode has to be armed and captured similarly to the lateral only NAV mode. The key difference is that the autopilot will also try and capture the vertical steering from the NAV1 receiver and follow the glide slope of the ILS. The approach mode has to be armed and captured similarly to the lateral only NAV mode.
