The engine is running now and can be warmed up. For quickest pos-
sible warming up it is recommended to keep engine speed below
2,500 rpm. Even at this low engine speed the engine is producing
waste-heat, but the cooling system is hardly supplied with fresh air.
Higher engine speeds improve cooling and therefore elongate the
warm-up phase.
In situations with high traffic on ground, e.g. taxiing for take-off at a
fly-in, coolant and oil temperatures can rise significantly. In such a sit-
uation either increase engine speed above 3,000 rpm to cool down the
engine or timely shut down engine. There is no danger the engine
could not fire-up again just because it is hot.
A magneto check in the common sense does not exist in the

; the REMOS SMARTstart takes over the check proce-
dure. Once the aircraft is arrested with the parking brake, engine
speed is set to 4,000 rpm and the ENGINE TEST button is hit. Follow-
ing procedure is executed in the background:
•
LANE A will be switched off and on again
•
LANE B will be switched off and on again
•
MAIN fuel pump is shut off
AUX fuel pump kicks in automatically
•
fuel system is reset so that MAIN fuel pump is active
The pilot only needs to monitor the engine parameter. A drop in engine
speed of not more than 180 rpm is acceptable, though in most cases
a slight increase of engine speed up to app. 4,200 rpm will be moni-
tored.
During the test of the engine parameters the MAIN fuel pump will be
switched off and the AUX pump will kick in immediately. The EMS
page of the SkyView system will generate an aural warning and the
“MAIN fuel pump INOP” warning light will come up. The warning will
expire after a couple of seconds. The engine will quit during test rou-
tine in case the AUX fuel pump is defective. Any malfunction on the
fuel system poses a certain risk on safe operation. Therefore, avoid
take-off with one fuel pump inoperative.
