Operations Flashcards
Short Field Landing
Power off approach at 69MPH 40° flaps Land on main wheels first Touch nose wheel Heavy braking
Cross Wind landing
Minimum flap setting for field length
Wing low top rudder
NMT 15 Mph wind (dependent on pilot capability)
Cold weather starts
Pull the prop several times to limber the oil
0°F and lower: use an external preheater (both battery and engine) and external power source
Preheat start
1) Clear prop
2) master switch ON
3) with ignition OFF and throttle closed, prime engine 4-8 strokes as prop is being turned over by hand
Use heavy primer strokes for best atomization
4) ignition to BOTH
5) Open throttle 1/4” and starter engage
Without Preheat start
1) prime 6-10 strokes while prop is being turned over by Hand. Leave primer charged
2) Clear propeller
3) master ON
4) ignition BOTH
5) pump throttle to full open twice, return to 1/4” open position
6) engage starter, continue to prime until running smoothly, or pump throttle over first 1/4” of travel
7) pull carb heat knot full on after engine started. Leave on until running smoothly
8) lock primer
If engine didn’t start in cold within the first few attempts it is probably because of________.
Spark plugs have frosted over. Preheat must be used before another start is attempted
Pumping the throttle may cause ______. If this occurs, maintain ______.
_______ is advisable for cold starts without preheat.
Accumulation of fuel in intake manifold, creating a fire hazard in the event of a backfire
Cranking action to suck flames into engine
Outside attendant with fire extinguisher
In cold weather ops oil temperature _____.
Will not be apparent on the oil temperature gage
In cold-weather operations after a suitable warm-up. _____ min @ ______ RPM, ______.
If the engine ______ and _____ remains normal and steady, ready for takeoff.
2-5 min @ 1000 Rpm
Accelerate the engine several times to higher engine RPM.
Accelerated smoothly / oil pressure
When operating in subzero temperature avoid using________.
Partial carburetor heat.
Partial heat may increase the carburetor air temperature to the 32 to 70° range where icing is critical under certain atmospheric conditions.
In hot weather avoid ______.
Prolonged engine operation on the ground.
Increase takeoff distance _____ for each _____ above standard temperature for a particular altitude.
10%, 25°F (14°C)
For operation on dry, grass runway increase distances (both “ground run” and “total to clear 50 ft obstacle”) by _______ of the total ________ number.
7%, “Total to clear 50’ obstacle”
For hot weather, decrease rate of climb ______ for each ______ above standard day temperature for a particular attitude
20 ft/min, 10°F
Reduce Landing distance ____ for each ______ headwind
10%, 5 knot
For operation on dry, grass runway, increase distances to LAND (both “ground roll” and “total to clear 50 FT”) by ______ of the ______ figure
20%, “Total to clear 50 FT obstacle”
