 What can you do to cool the engine?

• Enrichen the mixture

• Reduce the throttle

• Increase the airspeed

• Switch on the engine cooling fan

compared to a climb propeller which of these is true for a cruise propeller(select 3 that apply)

• More efficient for long range cruising

• Produce more drag

• Have a higher pitch

• More suitable for aerobatic flying

In which type of reciprocating engine are the cylinders arranged on the opposite side of the crankcase in order to provide  a high power wave ratio

• V-type engine

• Horizontally opposed, Circle formation engine

• Radial engine

• In-line engine

When decreasing power to a constant speed propellor the pilot should first reduce rpm before reducing manifold pressure

• No, you should reduce RPM and manifold pressure simultaneously

• No, you would pull the throttle first (manifold pressure)

• No, you should reduce manifold pressure first

• No, it doesn't matter which order you do it in

During which stroke of a reciprocating engine is the fuel air mixture ignited

• Suction

• Compression

• Exhaust

• Combustion or bang

What can happen when ice forms around the throttle valve in a float tight carburetor(select two that apply)

• Engine roughness from not getting enough fuel

• The engine would consume more fuel

• The engine would stop running

• You RPMs would go down on a set fixed propeller

• The engine would run smoother

At the end of your flight you perform a post flight mag check by turning the ignition switch to off, the check is pass but the engine continues to run

• No, the carburetor needs to be adjusted

• No, because its not grounded

• Yes, this is normal

• No, the spark plug needs to be replaced

Suppose you are taking of on an airplane on a cool day from an airport at sea level where should you send the air fuel mixture

• Full rich

• Full rich, you’d land half

• Full lean

• Full rich, you’d land 3/4

As aircraft gains altitude it eventually reaches its service ceiling. How do turbochargers increase their service ceiling?

• By using a supercharger instead of a turbocharger

• By reducing the amount of air going into the engine

• They increase the amount of air going into the engine. The turbine takes in more air, compresses it and forces it into the engine

• By increasing the weight of the aircraft

Why does the engine need oil(select three that apply)

• Cool the temperature

• To provide additional thrust

• Lubricating moving parts

• Cleansing 

• To reduce engine noise
