Cold Weather Ops - With Preheat engine_start

With ignition switch OFF and throttle closed, prime the engine four to ten strokes as the propeller is being turned over by hand
NOTEUse heavy strokes of primer for best atomization of fuel
NOTEAfter priming, push primer all the way in and turn to locked position to avoid possibility of engine drawing fuel through the primer

Continue to prime engine until it is running smoothly, or alternately pump throttle rapidly over first 1/4 of total travel
Source text reads 'l/4'; interpreted as 1/4.
Oil PressureCHECK
Pull carburetor heat knob full on after engine has started. Leave on until engine is running smoothly
PrimerLOCK
NOTEIf the engine does not start during the first few attempts, or if engine firing diminishes in strength, it is probable that the spark plugs have been frosted over. Preheat must be used before another start is attempted.
WARNINGPumping the throttle may cause raw fuel to accumulate in the intake air duct, creating a fire hazard in the event of a backfire. If this occurs, maintain a cranking action to suck flames into the engine. An outside attendant with a fire extinguisher is advised for cold starts without pre-heat.

Fires - Engine Fire During Start On Ground engine_fire_ground

Continue cranking in an attempt to get a start which would suck the flames and accumulated fuel through the carburetor and into the engine
If the start is successful, run the engine at 1700 RPM for a few minutes before shutting down to inspect the damage
If engine start is unsuccessful, continue cranking for two or three minutes with throttle full open while ground attendants obtain fire extinguishers
When ready to extinguish fire, discontinue cranking and turn off master switch, ignition switch, and fuel shutoff valve
Smother flames with fire extinguisher, seat cushion, wool blanket, or loose dirt. If practical, try to remove carburetor air filter if it is ablaze
Make a thorough inspection of fire damage, and repair or replace damaged components before conducting another flight

Emergency Descent Through Clouds inadvertent_imc

Apply full rich mixture
Use full carburetor heat
Reduce power to set up a 500 to 800 ft./min. rate of descent
Adjust the elevator trim tab for a stabilized descent at 80 MPH
Keep hands off the control wheel
Monitor turn coordinator and make corrections by rudder alone
Check trend of compass card movement and make cautious corrections with rudder to stop the turn
Upon breaking out of clouds, resume normal cruising flight

Recovery From A Spiral Dive unusual_attitude_recovery

Close the throttle
Stop the turn by using coordinated aileron and rudder control to align the symbolic aircraft in the turn coordinator with the horizon reference line
Cautiously apply elevator back pressure to slowly reduce the indicated airspeed to 80 MPH
Adjust the elevator trim control to maintain an 80 MPH glide
Keep hands off the control wheel, using rudder control to hold a straight heading
Apply carburetor heat
Clear engine occasionally, but avoid using enough power to disturb the trimmed glide
Upon breaking out of clouds, apply normal cruising power and resume flight
