Expanded Emergency & Abnormal Procedures
This section supplements and provides an expanded description of the
emergency and abnormal procedures included in the FAA approved
Aircraft Flight Manual Supplement. The data provided here is intended
to provide additional background information to enhance the pilot’s
understanding of the emergency and abnormal conditions, and the
associated procedures provided in the AFMS. This pilot guide is provided
for supplementary purposes only. The approved cockpit reference for in-
ight use is the AFMS, which must be immediately available to the pilot
at all times in ight. In the event of any conict between this document
and the FAA approved AFMS, the AFMS instructions must be followed.
6.1. Pitot/Static System Blockage
A pitot line blockage will result in the airspeed indicator behaving like an altimeter
when the aircraft’s altitude changes and it will not respond to airspeed changes. A pitot
line blockage can also aect the EFD1000’s attitude indication.
A static line blockage will result in altitude remaining xed and a zero vertical speed
despite aircraft pitch and/or power setting changes. In addition, IAS indications will
be incorrect if the static line is blocked. Errors will typically be noticed during climbs
or descents. When descending, ambient pressure increases which will result in the
indicated airspeed reading less than the actual airspeed. The opposite eect will
be observed in a climb. A static line blockage can also aect the EFD1000’s attitude
indication.
