EMERGENCY STATIC AIR SOURCE SYSTEM
THE EMERGENCY STATIC AIR SOURCE SHOULD BE USED
FOR CONDITIONS WHERE THE
NORMAL STATIC SOURCE
HAS BEEN OBSTRUCTED.
When the airplane has been
exposed to
moisture and/or icing conditions (especially on
the ground), the possibility of obstructed static ports
should
be considered. Partial obstructions will result in the rate of
climb indication being sluggish
during a climb or descent.
