1 . The Emergency Locator Transmitter that is required in an aircraft needs to be serviced how often according to the Canadian Aviation Regulations:
a ) Every six months,
b ) Annually,
c ) Every two years,
d ) Every five years
b) Annually: Source: Out of Phase Tasks and Equipment Maintenance Requirements, CARS 625.96 Technical Records Other than Journey Logs Schedule C, #12, Out of Phase Tasks and Equipment Maintenance Requirements.

2 . When Hovering in a no wind condition and the cyclic is moved forward to tilt the disc, the helicopter will settle as it moves forward because: a ) Total lift of the rotor is decreased,
b ) The horizontal component of lift is decreased,
c ) The vertical component of lift is increased,
d ) The total lift reaction remains unchanged but is divided into a lesser vertical component and some horizontal thrust.
d) The total lift reaction remains unchanged, but the vertical component or lift is reduced because the forward thrust takes away some of the lift. Increased collective will bring the lift back to where it was originally until you have translational lift. Source: Helicopter Aerodynamics.

3 . Ballots Law states; In the Northern Hemisphere, stand with your back to the wind and: a ) The Low Pressure Area will be on your left,
b ) The Low Pressure Area will be on your right,
c ) The High Pressure Area will be on your left,
d) The High Pressure Area is ahead of you.
a) The Low Pressure Area will be on your left: In the Northern Hemisphere, the High Pressure Areas rotate clockwise and the Low Pressure Areas rotate counter-clockwise. With your back to the wind, the Low Pressure area will be approximately on your Left Side.

4 . A semi-rigid rotor system allows the blades to:
a ) Flap and feather independent of each other,
b ) Flap together through the teeter hinge, lead and lag together and feather,
c ) Lead, lag, flap, feather independent of each other,
d ) Lead and lag together, but flap and feather independent of each other.
b) Flap together through the teeter hinge, lead and lad together and feather. The blades flap together as a unit, as one blade flaps up, the other flaps down; the blades will lead and lag together as they will both speed up and slow down together and they will feather through the control inputs through the swashplate and the pitch links.

5 . The instrument called the Turn and Bank with a ball and needle differs from the Turn Co-ordinator because:
a ) The Turn Co-ordinator shows the rate of turn more quickly,
b ) The Turn and Bank shows the rate of turner more quickly,
c ) The Turn Co-ordinator shows direction of turn only.
d ) The Turn and Bank only shows rate of turn.
a) The Turn Co-ordinator shows the rate of turn more quickly; The Turn Co-ordinator shows the direction and the rate of turn more quickly because the gyro is set at an angle of 30 degree from the longitudinal axis of the aircraft, therefore it will deflect the needle as soon as there is any bank or yaw of the aircraft. The Turn and Bank Indicator has the gyro mounted parallel to the longitudinal axis so the needle will deflect only when the aircraft yaws, and not when it initially banks for the turn.

6 . The VOR (VHF Omnidirectional Radio range) signal is subject to line of sight and reception varies according to aircraft altitude Above Ground Level (AGL) of:
a ) 2000 feet AGL is about 200 miles.
b ) 2000 feet AGL is about 100 miles.
c) 1500 feet AGL is about 150 miles.
d ) 1500 feet AGL is about 50 miles.
d) 1500 feet AGL is about 50 miles, or you can use the formula of: the square root of your altitude Above Ground Level times 1.23, equals the distance from the VOR transmitter that your VOR receiver is effective.

7 . Lines of Latitude are measured from:
a ) Greenwich England,
b ) The North Pole,
c ) The South Pole,
d ) The Centre of the Earth.
d) The Centre of the Earth: The Equator is Zero degrees measured for the Centre of the Earth and each degree of latitude is measured North or South of the Equator up to 90 degrees North (North Pole) and 90 degrees South (South Pole).

8 . What statements are true in regard to aviation fuels?
a) Fuels stored in drums lose the octane rating more quickly than fuel stored in plastic containers.
b ) When an aircraft is parked overnight, the fuel tanks should be topped up.
c ) A portable water separator pump should not be used when filling from drums.
d ) All the above.
b) When an aircraft is parked overnight, the fuel tanks should be topped up; this decreases the amount of air in the fuel tank. Water can condense from the air in the tank and pool at the bottom. This is why we drain the fuel in the tanks and gascolator (settling bowl) to ensure no water remains so it will not be pulled into the engine where it may cause a loss of power or engine failure.

9 . A Commercial Pilot Licence permits you to:
a ) Fly as Pilot in Command for hire any helicopter that you are endorsed on.
b ) Fly as Pilot in Command for hire any helicopter that you are endorsed on; and is commercially registered with a commercial helicopter operator.
c ) Fly Pilot in Command for hire any helicopter IFR (Instrument Flight Rules) with a Night Rating.
d ) Fly privately any helicopter in the light category.
b) Fly Pilot in Command any helicopter you are endorsed on; and is commercially registered with a commercial helicopter operator. A pilot can fly any helicopter for hire that they are endorsed on as long as the helicopter is registered commercially and with a Commercial Helicopter Operator. If the helicopter is not registered commercially with an Commercial Helicopter Operator it can only be flown privately.

1 0 .You are approaching a whiteout condition and you turn away performing a 180 degree level turn. After completing the turn, you may experience a feeling of:
a ) Descending.
b ) Climbing.
c ) A turn in the same direction
d ) A turn in the opposite direction.
d) A turn in the opposite direction: This is called the LEANS which is the most common illusion during flight. A gentle turn of 2 degrees per second or less will not be detected by the semi-circular canals in our inner ear which tells us which way is up (balance) and detects motion. Leveling the aircraft after a long gentle turn may cause the illusion that the aircraft is banking in the opposite direction.
