central pedestal.
If static source malfunction is suspected and/or abnormal fluctuations of
indicated airspeed and/or altitude are detected in relationship with yawing:

Operation of the alternate static air requires that the cabin air
system be switched off in order not to affect the air pressure
measurement.
