Engine Fire In Flight; Electrical Fire In Flight; Cabin Fire; Wing Fire - Cessna 150 COMMUTER 1976 Pilot Operating Handbook

SECTION 3
CESSNA
MODEL 150M
EMERGENCY PROCEDURES
ENGINE FIRE IN FLIGHT
(1) Mixture -- IDLE CUT-OFF.
(2) Fuel Shutoff Valve -- OFF.
(3) Master Switch -- OFF.
(4) Cabin Heat and Air -- OFF (except overhead vents).
(5)
Airs~eed
-- 85 KIAS (If fire is not extinguished, increase glide
speed to fmd an airspeed which will provide an incombustible mix-
ture).
(6) Forced Landing -- EXECUTE (as described in Emergency Land-
ing Without Engine Power).
ELECTRICAL FIRE IN FLIGHT
(1) Master Switch -- OFF.
(2) All Other Switches (except ignition switch) -- OFF.
(3) Vents/Cabin Air/Heat -- CLOSED.
(4) Fire Extinguisher -- ACTIVATE (if available).
If
fire appears out and electrical power is necessary for continuance
of flight :
(5) Master Swit ch -- ON.
(6) Circuit Br eaker s -- CHECK for faulty circuit, do not reset.
(7) Radio/Electrical Switches -- ON one at a time, with delay after
each until short circuit is localized.
(8) Vents/Cabin Air/Heat -- OPEN when it is ascertained that fire
is completely extinguished.
C ABIN FIRE
(1) Master Switch -- OFF.
(2) Vents/Cabin Air/Heat -- CLOSED (to a void drafts).
(3) Fire Extinguisher -- ACTIVATE (if availa ble ).
IWA RNING '
After discharging an extinguisher within a closed cabin,
ventilate the cabin.
(4) Land the airplane as soon as possible to inspect for damage.
WING FIRE
(1) Navigation Light Switch -- OFF.

SECTION 3
EMERGENCY PROCEDURES
(2) Pitot Heat Switch -- OFF.
ICING
NOTE
Perform a sideslip to keep the flames away from the
fuel tank and cabin, and land as soon as pOSSible, with
flaps retracted.
INADVERTENT ICING ENCOUNTER
(1) Turn pitot heat switch ON.
(2) Turn back or change altitude to obtain an outside air temperature
that is less conducive to icing.
(3) Pull cabin heat control full out to obtain maximum defroster air
temperature. For greater air flow at reduced temperatures, adjust
the cabin air control as required.
(4) Open the throttle to increase engine speed and minimize ice
build-up on propeller blades.
(5) Watch for signs of carburetor air filter ice and apply carburetor
heat as required. An unexpected loss in engine speed could be caused
by carburetor ice or air intake filter ice. Lean the mixture for maxi-
mum RPM, if carburetor heat is used continuously.
(6) Plan a landing at the nearest airport. With an extremely rapid
ice build-up, select a suitable "off airport" landing site.
(7) With an ice accumulation of 1/4 inch or more on the wing leading
edges, be prepared for significantly higher stall speed.
(8) Leave wing flaps retracted. With a severe ice build-up on the
horizontal tail, the change in wing wake airflow direction caused by
wing flap extension could result in a loss of elevator effectiveness.
(9) Open left window and
if
practical scrape ice from a portion of the
windshield for visibility in the landing approach.
(10) Perform a landing approach using a forward Slip, if necessary,
for improved visibility.
(11) Approach at 65 to 75 KIAS depending upon the amount of ice
accumulation.
(12) Perform a landing in level attitude.
LANDING WITH A FLAT MAIN TIRE
(1) Wing Flaps -- AS DESIRED.
(2) Elevator Control -- NOSE HIGH.
(3) Aileron Control -- BANK TOWARD GOOD TIRE.
