WARNING - Aircraft must be completely depressurized prior to opening any door. Failure to comply with this limitation could result in an accident, injury, or death.
Stall protection notes
- Stall protection system test must be accomplished before first flight of the day.
- Both stall protection switches must be ON for all phases of flight.
- Engine operation at or near shaker and pusher settings is predicated on an operable auto ignition system.
Use of flight spoilers
Policy - Flight spoilers must not be extended in flight below 1,000’ AGL (Manufacturer - 300’ AGL).
To ensure adequate maneuver margins, flight spoilers must not be extended in flight at airspeed below the recommended approach (Vref + 5 + 17) or maneuver (Vref + 10 + 17) speeds.
Bleed air - TO&L
10th stage bleed air must be closed for TO&L if the engine cowl &/or wing A/ICE systems are ON.

What are minimum altitudes for autopilot use?
Operation with the A/P engaged is prohibited at altitudes below 600’ AGL, except as follows:
- For visual and non-precision approaches - 400’ AGL

- IAW 14CFR121.579 - AWAC policy is to disconnect A/P at 50’ below the approved MDA or DH or listed limits, whichever is higher.
- The ADC source coupled to the active autopilot must the same as that coupled to the ATC transponder during flight in RVSM airspace.
Required RVSM equipment
- Autopilot (1) - must be operational
- Altitude alert system - must be operational
- Altitude reporting transponder (2) - one must be operational
- Air data computer (ADC) (2) - both must be operational
