Engine Check ground run only
Chock the main wheels before engine check. Initially warm up the engine at 2000 rpm
for two minutes then continue to 2500-2750 rpm until the oil temperature reaches 50°C
(
122 °F
). The warm up period depends on ambient air temperature.
Check both ignition circuits at 3500 - 4000 rpm. The engine speed drop with either
magneto switched off should not exceed 300 rpm. The maximum engine speed drop
difference between circuits A and B should be 120 rpm.
Idle speed should be no less than 1400rpm and max static power 4600rpm. The
throttle should be operated smoothly, check steady rpm change and smooth running
throughout this operation. Rough running should be avoided as this can lead to
damage, if rough running is detected the carburettors may need synchronising.
CAUTION
The engine check should be performed with the aircraft heading into wind and not
on loose terrain (the propeller may draw in debris which can damage the leading
edges of the blades).
4.4.5
Taxiing
The recommended taxiing speed is 8 knots or a steady walking pace. The aeroplane
can be steered by the steerable nose wheel. Hydraulic disc brakes are controlled by
toe levers on the top of the rudder pedals. Differential braking can also be used to aid
steering. During taxi to the hold the rudder pedal movement can be checked plus the
slip ball and DI/Compass
4.4.6
Before take-off checks
1. Brakes - fully applied.
2. Controls
- full and free correct direction
3. Harness & hatches
- Secure and hatches closed warning lamp off
4. Instruments
- all functioning and correctly set
5. Fuel
- tap open, pressure normal, quantity for flight, pump
on.
6. Flaps
- take-off position – (one notch = 15º)
7. Trim
- set to take of position 9in line with flap lever at one
notch
8. All clear
- area clear for a run up
9. Power
- Power checks run to full power if possible 4600rpm
min then to 3500 -4000 for a mag check, turn the key back two clicks note mag
drop, key back to both, after recovered rpm turn the key back one click again
note mag drop. Check all Ts&Ps are normal. Set throttle to minimum note idle
speed around 1400rpm. Increase power to smooth running setting.
10.
Wind check
- ATC or wind sock
11.
All clear
- check approach or as ATC
12.
Eventualities
- plan any actions in event of a problem
4.4.7 Take-off
By gradually increasing power, set the aircraft in motion.
The aeroplane can be steered by the nose wheel and/or by its hydraulic brakes.
Slightly pull the stick back to take the load off the nose wheel. The aircraft takes-off at
a speed above 40 knots. Slightly push the stick until the safety climb speed of 54
knots has been reached. The Maximum Flap Extended speed is 70 knots. Refer to
para. 5.2.5 for optimum climbing speed.
