ADC and s/by instruments
Max weight in the baggage compartment
45kg/100lbs
2 heating and ventilation systems
Heat exchanger in the engine nacelle providing warm air
NACA duct provides ambient air
NACA inlet is located
Just under the wing root
The cabin cooling system is made up of 3 parts
Aux power switch Central unit Additional alternator (RH side of engine)
Is the cabin cooling system connected to the electrical system
No, the additional alternator provides sufficient power
To turn the cabin cooler on/off
To turn on - aux power ON, press the on/off switch
To turn off - reverse but wait 1 sec after switching the on/off switch off
The aux power switch must be off during
T/o L/d GA Emerg/ abnormal ops procedures OAT is less than 10* (50*F) Above 10,000ft During the use of the ADF
Where is the fire axe located
Under the right hand seat
Aileron fixed trim tab is located
Port aileron
To remove power from the electric trim (trim runway)
Hold the autopilot disk button (red button)
Or
Pull the autopilot circuit breaker
Flaps are operated by
Electrically by push rods
Left and right are mechanically interconnected
3 flap posn and degrees
Up = 0*
T/o = 20*
L/d = 42*
L/d gear is made out of
Spring steel struts
The nose wheel is
Free-castering and spring loaded by an elastomer package
To operate the park brake
Pump the brake to build pressure
Select park brake to release while holding pressure on the brakes
Austro E4-A engine
4 cylinders Liquid cooled Common rail direct injection FADEC Turbocharged
Max power + max cont power
Max power = 100% at 5mins, 2300RPM
Max cont power = 92% at 2100RPM
The lubrication system
2 independent systems for the engine and the gearbox
Wet sump with an external filter and cooler
Engine and gearbox oil capacities
Engine = 7 litres (5 is min)
Gearbox = 2.1 litres - only serviceable by a mechanic
Some oil loss is normal (.1 lit/hr)
Gearbox oil system also operates
The variable pitch prop
Gearbox oil is
SHELL SPIRAX GSX 75W-80
SHELL SPIRAX S6 GXME 75W-80
Engine oil
Shell helix ultra
5W30/40
Fuel is delivered to a common rail via
LP and HP fuel pumps
Regulator/pressure relief valve controls the pressure
Rail supplies HP fuel to the injectors
Injectors are controlled by
ECU
Excess fuel is returned via a fuel cooler
The turbocharger uses
Filtered RAM air
In case of engine trouble, alternate air can be selected by pulling the alternate air lever - drawing air from inside the cowling
ECU FAIL CAUTION could be caused by
Sensor failures
Insufficient performance of air,fuel or electrical supply system e.g air filter icing
The propeller is made of
Wood/composite construction with stainless steel edge
ECUs control
Injectors
CSU
Rail pressure
Waste gate
Which fuel tank is main and which is auxiliary
Main = right Aux = left
Aluminium tanks in each wing
Fuel must be drawn from the aux tank to be used in the main tank
How many fuel pumps
2 parallel electrical LP fuel pumps
1 pump working at a time, when 1 fails then they switch
When the ECU switches from A to B then the fuel pumps also switch
4 sections of the electrical system
Power generation
Storage
Distribution
Consumers
Power generation
70a alternator - attached to the engine via a flat belt
2 x 12v, 7.2a batteries (ECU back up batteries)
ECU backup batteries can provide backup power to the ECU for
30mins for ECU B
Excite the alternators in case of a main battery failure
ACU
Monitors and controls output of the alternator
ALTN AMPS
ALTN FAIL
VOLTS LOW
ALTN AMPS = Output exceeds 70 amps
ALTN FAIL = alternator has failed
VOLTS LOW = engine bus voltage <25volts
Main battery
2.4v 13.6ah
Mounted behind the baggage compartment, on the right
Connected to the HOT BATTERY BUS and BATTERY BUS
Controlled by ELEC MASTER
Additional battery supplies power to
Backup attitude gyro
Flood light
Controlled on the emerg switch
1hr only - not rechargeable
Consumption of the battery bus 1
Starter heavy duty power
Battery bus 2
Battery bus 2 consumption
ECU BUS
Main bus
Ess bus
What provides a/c attitude and HDG info to the displays
AHRS
ADC processes pitot static and air temp info
