Sounds Great, Tracy.  Appears = you have=20 covered the most significant features already.

2.  How about tying it into your = airspeed=20 sensor to maintain a constant airspeed or could set in your Vne limits = {:>)=20 or maximum descent airspeed.

  a.  Take off and initial=20 Climbout
  b.  Cruise = climb
  c.  Best economy = cruise
