ALTERNATE AIR LIGHT DOES NOT ILLUMINATE
Press to test the alternate air door light to check for a bad circuit.
Then visually check that the ram inlet doors are in the ALT position
(Raised). If the doors are not raised, cycle the alternate air control
and check for reverse operation. If the ram inlet doors stay in the
NORM position (Down), leave the icing condition as soon as possible.
ALTERNATE AIR LIGHT ILLUMINATES IN FLIGHT
The alternate air door light can illuminate intermittently on takeoff or
high power, low speed climbs when in the normal air mode.
However, if the alternate air door light illuminates under normal flight
conditions, first check that the alternate air control is fully up in the
normal position. Then check if the ram inlet doors are in the alternate
air (raised) position. If the ram inlet doors are raised, cycle the
alternate air control to check for reverse operation. If the ram inlet
doors are not raised, land as soon as practicable and check for a
blocked inlet or a faulty micro-switch on the alternate air door.
STATIC SOURCE BLOCKED
If erroneous readings of the static source instruments (airspeed,
altimeter and rate-of-climb) are suspected, the alternate static source
valve should be pulled on, thereby supplying static pressure to these
instruments from the cabin.
NOTE
In an emergency on airplanes not
equipped with an alternate static source,
cabin pressure can be supplied to the
static pressure instruments by breaking
glass in the face of the rate-of-climb
indicator.
With the alternate static source on, adjust indicated airspeed slightly
during climb or approach according to the alternate static source
airspeed calibration table in Section 5.
SPINS
Intentional spins are prohibited in this airplane. Should an inadvertent spin
occur, the following recovery procedure should be used:
1. POWER CONTROL FLIGHT IDLE POSITION.
2. PLACE AILERONS IN NEUTRAL POSITION.
UNCONTROLLED
