4.Normal processes
4.1.Starting up the engine
Tasks which need to have be done especially before first startup of the engine in the flight day,
or in the case the engine had cooled down, are written in detail in the guidebook for the
maintenance for the engine of your airplane, which was delivered to you with other documents.
When starting up the engine, please keep to the device included in that handbook. Here are
included some of the principles.
-before starting up the engine, make sure all conditions for its safe starting up are kept / UL 1,
point 3.8.6/
-at a cool engine, turn over the airscrew several times in its direction for the oil from the
engine to be pushed in the tank
-if the airplane is equipped by adjustable airscrew, set it to the smallest angle of incidence
ATTENTION
Always do this task only when the both circles of ignition and the main switch is off
-open the fuel tap if is closed
-turn on the main switch
-turn on both ignition circuits
-at cool engine, pull out the saturator
-set the gas lever for no load, or 10% of the output
-proceed the starter in activity
- be starting up with no interruption for maximum 10sec.
If the engine is not started, let the starter cool down for about 2 minutes and then repeat the
starting. Overheated starter loses its output very quickly and the engine is hard to start with it
because it does not rev up to the sufficient amount engine revolutions.
4.2.Engine test
The engine test is made when the engine is warmed up with the goal to verify its operating
efficiency. The procedure for the warming up the engine and making the test of ignition is again
introduced in its full length in the handbook for the engine, keep to the procedures enclosed
there.
We initiate only the basic principles:
-let the engine run for about 2 minutes with the revolutions of 2000/minute and continue with
its warming up with the revolutions of 2500/min till the oil temperature does not reach
50*Celsius. Check the temperatures and the pressures while warming up and if all operating
values have been reached
-do the test of ignition at the revolutions of 4000/min, the drop of the revolutions for each
circuit can not be higher than 300 revolutions per minute, the difference of the revolutions can
not reach more than 120revolutions per minute. If you find out that there is no drop of the
revolutions, it can mean that interruption of the short circuit cable, which turns off the ignition
circuit, has occurred. In this case try to turn off the engine. If the engine would not turn off
after turning off both ignition circuits, stop the fuel supply to the engine and let the engine
come down. Check the connection of the connectors of the ignition circuit / under the engine
hood / .
