Systems

Question 1

Answer 1

Semi monocoque shell structure made from carbon fibre reinforced plastic (CRFP) with glass fibre reinforced plastic bulkeads

Firewall comprising of fire resistant matting separating the engine nacelles from the rest of the structure

Answer 3

52 US Gal

Question 4

Max usable fuel

Answer 4

50 US Gal

Question 5

Max fuel imbalance

Answer 5

5 US Gal

Question 6

Max Masses]

Min flight mass
Max ramp
MTOM
MZFM
MLM

Answer 6

Min flight mass = 1250kg
Max ramp = 1793kg
MTOM = 1785kg
MZFM = 1650kg
MLM = 1700kg

Question 7

Seat construction

Answer 7

Kevlar and GRFP

Question 8

Fire extinguisher, first aid kit and ELT location

Answer 8

Fire extinguisher, behind the copilots seat

First aid, in the rear baggage compartment

ELT, rear fuselage below the baggage compartment. The aerial is fitted to the top of the fuselage

Question 9

How long does the ELT transmit for after a crash

Answer 9

It transmits on VHF, UHF and satellite emergency frequencies for 72 hours

Question 10

Cabin heating system

Answer 10

Air is drawn in from each engine nacelle, passes through the engines heat exchanger allowing the hot coolant that passes through the heat exchanger to heat the air

Question 11

Different uses for the right/left heat exchangers

Answer 11

Right = canopy demisting 
Left = cabin heating

Question 12

Cabin ventilation

Answer 12

Ambient air flows through a NACA duct on the right wing, providing cabin ventilation. This can be controlled by a number of ventilation ducts in the cockpit.

Question 13

The trim switch is guarded from trim runaway by

Answer 13

A dual pole design, both switches need to be moved to move the trim.

If only one part is moved and held for 3 seconds then the system detects a fault and disconnects

Question 14

Elevator stick limiter operation and number of degrees

Answer 14

Limits aft stick movement when the power setting on both engines exceed 20% and flaps are set to landing

The elevator goes from 15.5* to 13* max deflection

Question 15

Flap degrees and Vfe for each stage

Answer 15

Cruise (up) = 0* Green
Approach (APP) = 20* White 137kts
Landing (LDG) 42* White 111kts

Question 16

White speed tape speed range

Answer 16

56 to 111kts

care must be taken when selecting APP flap as 137 is in the green range

Question 17

Type of stall warning fitted

Answer 17

Electrical flapper, lift detector vane in the flight manual

Question 18

Type of engines

Answer 18

Two, four cylinder, liquid cooled, turbo charged Thielert TAE 125 four stroke diesel engines.

Both propellers are controled by a reduction gearbox

Question 19

The FADEC controls

Answer 19

Engine fuel system, propeller and the turbo charger system

Question 20

Engine lubrication system and capacity

Answer 20

Wet sump system with an external filter and oil cooler. An engine driven pump provides provides the oil flow

Oil capacity = 6L

Max consumption is about 0.1L

Question 21

Approved oils

Answer 21

Shell helix ultra 5W40 synthetic and Aero Shell 10w40 Diesel Oil are approved for engine use.

Gearbox = Shell EP 75W90 API GL-4

Question 22

Oil temp and pressure warnings illuminate when

Answer 22

Pressure = 1.2 bar
Temperature = greater than 140C
Gearbox temp = greater than 120C

Question 23

Engine cooling system

Answer 23

Liquid cooled. The liquid coolant is pumped around the engine by a belt driven integral pump

Question 24

The aircraft uses a CSU to control propeller pitch, what moves to coarsen or fine the blade angle

Answer 24

Oil pressure is used to move towards fine ptich

A spring moves it to coarse pitch

Question 25

Centrifugal twisting moments cause

Answer 25

Act towards fine pitch

while centrifugal twisting mometns of counterweights act in the opposite direction

Question 26

How is propeller unfeathered

Answer 26

It uses oil stored under pressure in an accumulator charged with nitrogen gas

Question 27

Min RPM for the propeller to feather

Answer 27

Propeller speed needs to exceed 1300RPM

Centrifugal force acting on the propeller blade counterweights and spring move the blades to the feathered position

Question 28

If both alternators fail the ECUs will be supplied with battery power for how long

Answer 28

30mins

Question 29

If an ECU FAIL caption is seen on the PFD, you can try and reset the ECU by

Answer 29

Pressing and holding the ECU test button for 2 secs

Question 30

ENG Fire warning illuminates when

Answer 30

Compartment temp is above 250*C
