To stop draining of fuel from the vent lines on the ground, what do you do?
Use one fuel tank only
What is necessary, if oil temperature is under 50 degrees Celsius doing starting engine check?
Priming is necessary

10, 20, 6, 6, 30
If the RH magneto switch is turned on before the engine fires, what might happen?
The engine will probably backfire thus damaging the starter
If minimum oil pressure (25 psi) is not indicated within 30 seconds after engine start, what should you do?
Stop engine
After “Engine Start” the GEN caution light may illuminate due to what? and when is this condition acceptable?
- Low system voltage
- On ground only
After “Engine Start” the engine RPM should be ___ RPM whenever possible.
1200 RPM
After “Engine start” which 2 things should you avoid doing under ground operations?
- Avoid prolonged engine ground operation at “idle” RPM
- Avoid rapid engine speed changes after start-up, and use only the power settings required to taxi.
At temperatures below -15 degrees Celsius, what should be preheated before starting engine?
The oil
How is “GROUND RUNNING AND WARM-UP” performed?
- Leave mixture in position FUEL RICH. Operate only with the propeller control in position
HIGH RPM. - During hot weather or hot engine ground operation where fuel vapor problems cause erratic engine operation, turn on Aux. fuel pump.
- Engine is warm enough when throttle can be opened with smooth and proper engine response.
What problems can RPM less than 1200 cause when parked?
- May damage the engine
- Increase the settling of lead in cylinders and on sparkplugs
Do not exceed ___ RPM on ground except during take-off.
2500 RPM
In which areas should pilots avoid run-up and why?
Pilots should avoid run-up in areas with loose articles (gravel, stone etc.), because the suction from the propeller may lift these articles and thereby cause damage to the propeller and other sections of the aircraft body
What is important to do, if night flying is planned?
Check operation of all lights, internal/external, and make sure a flash light is available
What is needed to check the function of map lights?
The EPU must be turned on to power the emergency bus
Use low engine RPM when taxiing on gravel or sod strips. Taxi slowly, especially during ____. Never attempt taxiing in wind velocities of more than ___ kts.
Use extreme caution in wind velocities of more than ___ kts.
- Winther
- 50 kts
- 25 kts
Taxiing in slush may cause what and why? How do you prevent this?
May cause the static ports to get blocked by ice due to splash from the main wheels
Taxi speed should be as low as possible
Doing sharp turns when taxiing, what might happen? How do you stop this?
Fuel overflow from the outboard tank, especially when the fuel selector is in position BOTH ON
To stop siphoning of fuel from either tank, select left or right tank ON
Under “ENGINE RUN UP” if requirements in checks 1-4 are not met, what do you do?
Warm up engine until ENG OIL TEMP is in the normal operating range, and then perform a new check
Caution must be exercised when using the Mixture control Leaver. Why is that?
Mixture control Leaver must return to full rich, before the RPM can drop to a point where the Engine Cuts Out
Under “ENGINE RUN UP”, how do you know if idle mixture is excessively rich or too lean?
An RPM increase of 50 RPM or more indicates an excessively Rich Idle Mixture
An Immediate decrease in RPM, if not preceded by an increase, indicates the Idle Mixture is too Lean
Under “ENGINE RUN UP” if the RPM drop exceeds 175 RPM, what do you do?
slowly lean the mixture until the RPM peaks. Then retard the throttle to the specified 2000 rpm for the magneto check and repeat the check
If “Engine Run-Up” shows magneto drop out of limit and/or uneven engine run, what do you do?
- Both magnetos “ON”
- Set RPM to 2500 RPM
- Lean to peak EGT
- Run the engine for 30-40 seconds at peak EGT
- Reduce to 1200 RPM
- Mixture rich
How many times can you perform a new engine run-up check, if magneto drop is out of limits, and what do you do after?
Once else you have too ground abort aircraft
Doing take-off what should you avoid and why?
Rapid opening and/or closing of the throttle.
May detune the crankshaft counterweights with subsequent engine damage
Full range throttle movements should be performed over a ______.
minimum duration of 2 seconds
Over-rotation of the aircraft during take-off, will increase ____.
ground roll distance
After nose wheel lift-off, the nose wheel strut does what?
automatically lock in center position
Under take-off a higher than normal engine RPM may be expected when what and what should you do to fix this?
The engine oil temperature is below normal operating range (green area)
Propeller lever should be retarded to 2700 RPM in order not to exceed the maximum engine RPM limit
Minimum RPM for take-off with full power is ___.
2670 RPM
MAXIMUM PERFORMANCE TAKE-OFF settings?
- 10° flaps
- At 2500 RPM release the brakes
- ROTATION and LIFT-OFF SPEEDS should be 5 kts lower than normal
Should you use flaps under CROSSWIND TAKE-OFF?
It is recommended not to use flaps and to keep the nose wheel on ground until lift-off speed is obtained
What should be done at high density altitudes and/or high ambient temperatures (above +40° C) during take-off?
Auxiliary fuel pump should be left ON during the entire climb
Why should you be cautious with passengers in the front seat?
When retarding mixture beyond the detent, the passenger may cut off of the fuel unintentionally
When leaning what do you lean to peak?
EGT or max Cylinder Head Temperature (CHT) normal range limit whichever comes first
If roughness is encountered doing leaning, what should you do?
Enrich the mixture slightly for smooth engine operation
Never lean to peak EGT or max CHT beyond ______ power
75%
When airborne the auxiliary fuel pump should be ON during the following conditions:
- When flying below 500 ft AGL.
- During any airborne utilization of the fuel selector, until the operator is assured that there will be no interruption of the fuel flow (5 seconds).
- Any time the fuel flow is fluctuating or the engine is affected by the fluctuation.
Flying with full tanks and the fuel selector in position BOTH ON may cause what? How is this fixed?
- Siphoning of fuel from either tank
- Set fuel selector in position LEFT or RIGHT ON and the siphoning will stop within 10-15 sec
To correct a fuel imbalance in air due to siphoning, what can you do?
- Fuel selector - BOTH ON
- Yaw (skid) the aircraft to the side with low fuel state, using ½-1 ball width
Correcting a fuel imbalance by skidding the aircraft under IMC may cause what?
Spatial disorientation
Is it allowed to switch off strobe lights in flight
If they interfere when flying IMC
TO INCREASE POWER what do you do?
First, enrich mixture, then follow with throttle
TO DECREASE POWER what do you do?
First, reduce throttle, and then adjust mixture
Why should movement of the propeller control lever be slow?
Since slight movement will cause considerable RPM change
Whenever mixture is adjusted, rich or lean, it should be done ___.
slowly
Under “BEFORE LANDING” before selecting HIGH RPM, what should you do if using a high power setting?
If using a high power setting, reduce power, before selecting high RPM
How much should base and final speed increase when “ALT STATIC AIR” is selected?
10 kts
When should base and final speed increase 5 knots?
- No-flap landing
- If the aircraft gross weight is above 1050 kg
When winds are gusty, what do you add to final airspeed?
One-half the gust factor
Too rapid movement of the throttle may cause what?
Engine over speed
During high ambient temperatures (above +40° C), what should be done under taxiing back to apron and why?
Auxiliary fuel pump should be left ON
This eliminates any vapor-lock forming in the fuel lines
Under “SHUT DOWN” how long should RPM be kept at 1800 before “Mixture cut-off”?
15 to 20 sec
Before “ENGINE SHUT DOWN” engine RPM should be set at ____ RPM until oil temperature has stabilized.
1200 RPM
What should you make sure of, when leaving the cockpit?
That the shoulder harness is inside before closing the canopy
Can you leave the canopy open when leaving aircraft?
No, strong winds can damage hinges/dampers. Furthermore the canopy could in some cases converge sun rays making it a fire hazard.
