Where is the External Power Receptable
External Power Receptable
Essential bus switch ==> When is it used
When the alternator fails to disconnect unnecessary electrical consumers to supply battery power to essential electrical consumers
-
Performance data which are engine-power dependant cannot be determined by just using „Density Altitude“! Why?
-
he engine power output does not correspond to density altitude but pressure and temperature have their own, independent influence

How is the function of the wheel brake?
Hydraulically operating disk
Wieso ist es ein passives hydraulic system?
müssen zuerst Druck geben
How is the function of the parking brakes?
a) pull the lever downwards until it catches (Parkingbrakes setzten)
b) Brakes drücken => Brake pressure is built up by multiciple operatin of the toe brake pedals => One way valve is closed
c) is maintained until the parking brake is released
What happens when the copilot applies brake?
hydraulic geht über die Premsen den CMD zum brake cylinder right
The harnesses

Without a baggage net
no baggage may be loaded
cooling gap what's that?
gap under the forward canopy
Can you operating with the cooling gap?
You can, but only on the ground
What prevents the rear door from dropping?
a gas pressure damper
Must starting the engine, the door must be
closed and latched, but not key-locked

ECU Voter Function
ECU = Electrical Control Unit Normal: AUTO => engine is controlled by either ECU A or ECU B (Computer not in work = HOT STANDBY) => Kann Manually switching = only in emergency
ECU TEST
pushing and holding the button until the end of the procedure => Self Test only on ground
What happens when you switch from one to another ECU Computer
a slight shake of the engine
Alternate Air => Für was ? von wo komtm dann die Luft=
icing or other blockage of the air filter => air from the engine compartment => is located under den instrument panel on the left side of the center console

Open
Welches Oil wird beim propeller verwendet ?
gear box
Aus was besteht der Propeller
The propeller has a wood-composite blades with fibre-reinforced plastic coating
How you can change the blade pitch? wer macht das?
Gear pox oil is pumped into the propeller hub which leads to an increase in pitch and a lower propeller RPM => set by ECU via an electro mechanical actuator

Common Rail System
Fuel System wie viel Kapazität?
2x 15 USG => 2Y 14 USG usable = 28 USG = 95 KG
Verbrauch Fuel?
AT 75%: ca. 6.5 USG/hr
Fuel Valve 3 Positionen
NORMAL; EMERGENCY; OFF
Normally fuel is taken from the
Main tank (left Wing)
How is the fue injected?
with high pressure directly into the combustion chambers
How is the pressure inside the fuel generated?
is generated by a high pressure pump which receives fuel from two independent low pressure fuel pumps => powered electrically
What happens by the EMERGENCY FUEL Schalter
the transferring of fuel with the help of the electrically driven and engine driven fuel pumps from the auxiliary tank through the fuel return line to the to the main tank
