3.6.2) Take-off (as per RTCA DO 178 B - with inactive TCU)
3.7) Cruising
Performance
Oil temperature
3.8) Engine shut-off
General note Normally the cooling down of the engine during descending and
taxiing will be sufficient to allow the engine to be shut off as soon
as the aircraft is stopped.
At increased operating temperatures make an engine cooling run
of at least minimum 2 minutes.
Any improper use of the TCU-switch will be
recorded by the TCU. At exceeding of the lim-
its of operation will render any claims on
ROTAX null and void.
Step Procedure
1 Switch on the auxiliary fuel pump.
2 Move throttle lever to 115 % (take-off performance).
3 Set take-off power until the boost pressure stabilizes within
the limits of operation.
4 TCU-switch in “OFF“ position.
5 After reaching the critical altitude switch on the TCU.
6 The auxiliary fuel pump should be switched off after the
take-off.
Step Procedure
1
Set performance as per performance specifications
Chapter 5) and respect operating limits as per Chapter
2.1).
Step Procedure
1 Avoid operation below normal operation oil temperature
(90 to 110 °C / 194 to 230 °F), as possible formation of
condensation water in the lubrication system badly influ-
ences the oil quality.
To evaporate accumulated condensation operate engine
at over 100 °C (212 °F) oil temperature for a minimum of
10 min. every flight day.
