|---|
| 2 | 0 | 1 | Which version of the A109 introduced composite fuselage structures? | AW109SP | A109S | A109E |
|---|
| 3 | 0 | 1 | How is the Main rotor system of the A109 best descibed? | Fully articulated main rotor with four composite blades and a titanium Main Rotor Head | Fully articulated main rotor with four composite blades and a alloy steel Main Rotor Head | Semi rigid main rotor head with four alloy and composite main rotor blades |
|---|
| 4 | 0 | 1 | What are the primary differences between the A109 E/S and the SP? | The SP introduces a composite fuselage structure and 4 axis auto pilot system | The SP introduces a composite fuselage structure and 3 screen glass ****pit PFD/MFD system | The SP introduces shrouded tail rotor and integrated mission computer FMS system |
|---|
| 5 | 21 | 1 | How many defusers in the passenger compartment are supplied by the nose ram air intake? | 2 | 4 | 6 |
|---|
| 6 | 21 | 2 | The A109SP avioinc cooling system has; | 3 fans, a Low speed detector and “EFIS FAN” caution light on EDU #1. | 4 fans with low speed protection triggering the MCL | Low speed detector and caution switch on instrument panel. |
|---|
| 7 | 21 | 3 | In case of ENG FIRE: | All AW109 E/S/SP DAU will close both shut off valves | A109E DAU will close only affected engine SOV. | A 109S/SP DAU will close only affected engine SOV. |
|---|
| 8 | 21 | 2 | Where is the ECS over temperature switch located? | In the plenum chanber duct assembly | In the Pilot vent tube | In the Co-pilot vent tube |
|---|
| 9 | 21 | 3 | How are the engine SOVs operated | Opened by a pressure differential controlled by a solenoid and sprung closed with bleed air pressure assisting in closure | Closed by an electrical solenoid and opened by bleed air. | Sprung closed and opened by an electrical motor |
|---|
| 10 | 21 | 3 | What is the function of the Economy solenoid valve | When switched to ECON the economy solenoid valve is de- energized and opens, this increases the actuating pressure supplied to the turbine inlet control valve, reducing turbine speed | When switched to ECON the economy solenoid valve reduces bleed air pressure supply by aadjusting the venturi tube in the plenum chamber | When switched to Econ the fan motor speed is reduced, using less energy from the 28V main bus |
|---|
| 11 | 21 | 2 | The basic ventilation system configuration consists of: | Ram air intakes located in the nose and on the forward MRGB cowling | Ram Air Intakes located in the nose between pilot and copilot windshield and an upper deck air scoop which are both interconnected | Twin ram air ducts below the windscreen and an upper ram air duct feeding the cabin. |
|---|
| 12 | 21 | 3 | What happens if there is a bleed air over temperature condition | The bleed air over temp switch provides an earth to the ECS control relay and removes power from the engine SOVs | The bleed air over temp switch provides an earth to the DAU which closes the engine SOVs | The bleed air over temp switch removes the earth from the engine SOVs causing them to open. |
|---|
| 13 | 21 | 3 | What indication does the pilot have of ECS funcitonality | Overhead switch positions and ECS advisory message | Overhead switch position, ECS advisory message and ECS FAIL caution message | Overhead switch position only |
|---|
| 14 | 22 | 3 | When GA mode is activated at less than 55knts what does the aircraft do? | Commands a level attitide and zero rate of climb | Commands a nose up attitide and a 750 feet per minute rate of climb | Commands a level attitide and zero to 750 feet per minute rate of climb |
|---|
| 15 | 22 | 3 | Where do the autopliot cyclic position sensors get their power from ? | The pitch position synchros are powered by the 26VAC bus | The pitch position resolvers are powered by the 115VAC bus | The pitch position Synchros are powered by the 28VDC bus |
|---|
| 16 | 22 | 3 | What colour are the EADI FD decoupled annunciations? | Magenta | Green | Cyan |
|---|
| 17 | 22 | 3 | In attitude hold mode disengaged….? | The trim actuators do not attempt to recentre the linear acutators | The linear actuators are centred throughout the operating range | The FD system only shows sterring advisories |
|---|
| 18 | 22 | 3 | The electro magnetic clutch within the parallel actuators is….....? | Energised on to anchor the flight controls | De-energised to anchor the flight controls | Energised by an internal microswitch to anchor the flight control |
|---|
| 19 | 22 | 2 | How is FCC cooling achieved? | Via two blower fans on the FCC | Via ducting from the avionics cooling fans | Via FCC case fins and ambient conditions in the avionics compartment |
|---|
| 20 | 22 | 3 | What is the purpose of the collective control overide function | Provides low height and power limit protection | Allows the pilot to override the FCS collective control | Prevents the FCS collective control from over powering the pilots commands |
|---|
| 21 | 22 | 3 | What impact on the AP system would an inverter 1 failure have? | No impact as the number 2 inverter will supply both systems | The autopilot system degrade with non critical functions disabled | The number 1 channel will trip offline and number 2 will take over full control |
|---|
| 22 | 22 | 2 | How many linear actuators are there in the A109SP auto flight system? | 6 | 5 | 3 |
|---|
| 23 | 22 | 3 | How many trim actuators are there in the A109E auto flight system? | 3 | 4 | 2 |
