CHAPTER 76 - ENGINE CONTROLS
Engine control consists of engine power lever / throttle with choke and related cockpit switches for
engine shut-down and test.
76-10-00 Power Control / Choke
Engine power / throttle is controlled by a control
column located on the left side of the pilot station.
The unit combines a choke control (3) as well as a
lever for activation of the wheel brake.
Throttle control (1) is conventional with IDLE in aft
(or pulled) and full throttle in most forward
position. With the ROTAX 914 UL engine the
boost range is entered by overcoming a small
resistance to the front. The throttle lever is linked
with cable controls to the carburettors. A
mechanical spring applies tension to the control
cables and brings the carburettors to full throttle in
case of a cable break. The throttle lever has a pre-
set friction brake which holds the throttle in the
selected position.
Choke (3) is used start a cold engine. In order to
do so, pull the choke lever fully to the rear or ON
position and be sure to have the throttle in idle
position. After starting the engine and a short
warm-up, the choke can be slowly disengaged by
moving the lever into its forward or OFF position.
76-20-00 Engine Shutdown /
Emergency
For normal and emergency shutdown, a pair of magneto switches (MAG 1 + MAG 2) is installed in the
cockpit centre panel. The magneto switches are also used for testing the individual ignition circuits.
CHAPTER 77 - ENGINE INDICATING
All relevant engine parameters are displayed in the cockpit, using analogue-type instruments in
standard version. In case of integrated cockpit systems (option), engine data may be displayed in the
integrated instrumentation system (glass cockpit). An hour meter (Hobbs Meter) is installed in the
cockpit to count engine operating time with an accuracy of two decimals (1/100 hrs). Although the
‘engine operating time’ is also used for total aircraft hours counting, the hour meter is allocated to this
chapter as the main function.
77-10-00 Power
With a piston engine with fixed pitch propeller, engine power indication solely consists of an engine
RPM indicator. In case a variable pitch propeller is installed, a manifold absolute pressure (MAP)
indicator is provided in addition. See
CHAPTER 31 for different cockpit layouts.
77-20-00 Temperature
For temperature indication, a cylinder head temperature (CHT) gauge is provided. Due to the engine
cooling principle (air cooled cylinders with water cooled cylinder heads) the CHT represents water
temperature at cylinder 2 head.
Oil temperature indication is described in CHAPTER 79
