4.6 Invalid Attitude & Heading
Figure 17. Invalid Attitude and Heading
If valid attitude and heading data becomes unavailable, attitude data,
wind vector data, heading data, and HSI navigation data are removed
from the display.
Note: You may be able to recover from a failed attitude condition by pulling
both PFD circuit breakers for less than 20 seconds. This will initiate a
warmstart as described in Section 4.4, "Warmstart Conditions" on page 45.
!
If warmstart is unsuccessful, use back-up instruments for
attitude and heading for the remainder of the flight. During IFR
flights, proceed to the nearest VMC conditions and do not re-
enter IMC.
Note: For autopilot-equipped aircraft, consider using the autopilot to reduce
workload. Use GPSS mode to maintain the flight plan route.
