Event 6 - The autopilot actuator monitor (AAM) monitors the difference between the A/P roll command and the follow-up (A/P LVDT). 1) The AAM trips at four degrees with a variable time delay
 of 10 degree-second. For example, if the difference between the A/P roll command and the LVDT is 4 degrees the time delay would be 10 divided by 4 or approximately 2.5 seconds.
 2)  The surface position monitor (SPM) monitors the difference between the A/P actuator A/P LVDT and the surface position sensor. The SPM trips at 3 degrees with a variable time delay. At altitudes above 60 feet the delay is 30 degree-second for both channels out of tolerance. At altitudes below 60 feet the delay is reduced to 6 degree-second.
