Eiri KY PIK-20 E - Ground Test; Before Takeoff; Takeoff

PIK-20 E Flight manual
A
On a normal grass field it is easy to taxy alone with help of the stee
rable tailwheel. The ground clearance at the lower wing should be taken
into account. The turning radius is smaller when turning around the
lower wing.
The proper function of the wheel brake should be checked before
taxiing.
On soft ground eg. sand with C. of G. in the foreward position and
with water ballast tanks partly filled some experience is required to taxy
without assistance, especially in strong crosswind. It is then easier to
have an assistant walking at the wing tip.
When turning in windy conditions, it is normally easier to keep the
wing turned to the wind, and then turn around the lower wing tip.
When taxiing longer distandes in good conditions, eg. on a runway,
the wings may be levelled and taxiing made only on the main wheel.
5.9 Ground test
When the engine is warm, it can be tested for proper running. When the
engine is functioning properly, it must run at least 5600 rpm smoothly.
The test can be done shortly or during taxiing, so the nose does not
go down. The throttle can be pushed with a rather fast movement to
get a good rpm response.
The function of the alternator can be checked from the battery volta 
ge gauge. Proper alternator function should raise the gauge to the hig 
her voltage area.
By turning the electric fuel pump off, the function of the engine's
own fuel pump can be tested. The engine should run smoothly at all
power settings with its own fuel pump.
5.10 Before takeoff
The pre-flight check must be done before the takeoff. The electric fuel
pump must be on and the choke must be fully off and the decompressor
closed.
5.11 Takeoff
During a normal takeoff flaps should be +4° down or neutral. The trim
is about 1/4 from aft position with the C. of G. in central position.
