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 andjor icing conditions
(especially on the ground), the possibility of obstructed
static ports should be considered . Partia! obstructions will
result in the rate of climb indication being sluggish during
a cli mb or descent. Verification of suspected obstruction is
possible by switching to the emergency system and noting
a sudden sustained change in rate of climb. This may be
accompanied by abnormal indicated airspeed and altitude
changes beyond normai calibration differences.
Whenever any obstruction exists in the Normai Static Air
System or the Emergency Static Air System is desired for
use:
1. Pilot's Emergency Static Air Source - Switch to ON
EMERGENCY.
2. For Airspeed Calibration and Altimeter Correction,
refer to PERFORMANCE section.
CAUT/ON
Be certain the emergency static air valve is in
the NORMAL position when system is not
needed.
