Emergency Procedures 400T(TX) Loss of Airspeed

Note: If the pilot's, or copilot's and standby, or all three airspeed(s) are noted to be decreasing toward zero, refer to the standby attitude indicator, standby altimeter, standby heading and the AOA indicator for aircraft control and land at the nearest suitable airport. The pilot's and copilots altimeter's, attitude displays and heading displays may be unreliable and the autopilot may disconnect. This may be accompanied by amber boxed A/S, ALT, ATT and/or HDG comparator flags. The comparator flags may be followed by red FAIL flags on the airspeed, altitude, attitude and heading displays.

Autopilot \- Disconnect
Airspeed \- Slow to and Maintain 0.2 AOA
Thrust \- As Required
Speed Brakes - As Required (Slow to 0.25 AOA with speed brakes extended)

Note: An AOA of 0.2 (0.25 speed brakes extended) will yield an airspeed of about 210 knots. Use pitch attitude as primary reference. Make small changes in pitch attitude and wait for AOA to stabilize.

When Ready for Descent

5. Seat Belts/Shoulder Harnesses \- Fastened
6. Cabin Sign \- As Required
7. Anti/DeIce Systems \- As Required
