M2 Quiz

In what flight condition are torque effects more pronounced in a single-engine airplane?

• Low airspeed, high power, high angle of attack

• Low airspeed, low power, low angle of attack

• High power, high speed, high angle of attack

The left turning tendency of an airplane caused by P-factor is the result of the

• clockwise rotation of the engine and the propeller turning the airplane counterclockwise

• propeller blade descending on the right, producing more thrust than the ascending blade on the left

• gyroscopic forces applied to the rotating propeller blades acting 90 degrees in advance of the point the force was applied

When does P-factor cause the airplane to yaw to the left?

• When at low angles of attack

• When at high angles of attack

• When at high airspeeds

Excessively high engine temperatures will

• cause damage to heat conducting hoses and warping of the cylinder cooling fins

• cause loss of power, excessive oil consumption, and permanent internal engine damage

• not appreciably affect an aircraft engine

Excessively high engine temperatures, either in the air or on the ground will

• increase fuel consumption and may increase power due to the increased heat

• result in damage to heat conducting hoses and warping of cylinder cooling fans

• cause loss of power, excessive oil consumption, and possible permanent internal engine damage

If the engine oil temperature and cylinder head temperature gauges have exceeded their operating range, the pilot may have been operating with

• the mixture set too rich

• higher-than-normal oil pressure

• too much power and with the mixture set too lean

One purpose of the dual ignition system on an aircraft engine is to provide for

• improved engine performance

• uniform heat distribution

• balanced cylinder head pressure

An electrical system failure (battery and alternator) occurs during flight. In this situation, you would

• experience avionics equipment failure

• probably experience failure of the engine ignition switches, fuel gauges, aircraft lighting system, and avionics equipment

• probably experience engine failure due to the loss of the engine driven fuel pump and also experience failure of the radio equipment, lights and all instruments that require alternating current

If the ground wire between the magneto and the ground switch becomes disconnected, the most noticeable result will be that the engine

• will run very rough

• cannot be started with the switch in the ON position

• cannot be shut down by turning the switch to the OFF position

On aircraft equipped with fuel pumps, when is the auxiliary electric driven pump used?

• All the time, to aid the engine driven fuel pump

• In the event the engine driven fuel pump fails

• Constantly, except in starting the engine
