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

• Low airspeed, high power, high angle of attack

• Low airspeed, low power, low angle of attack

• High airspeed, high power, 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 rotation propeller blades acting 90° 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

• Wen 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 possible 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 the cylinder head temperature gauges have exceeded their normal 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 system, 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

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

• All the time, to said the engine-driven fuel pump

• Difference in air pressure at the venturi throat and the air inlet

• Increase in air velocity in the throat of a venturi causing an increase in air pressure

The operating principle of float-type carburetors is based on the

• Automatic metering of air at the Venturi as the aircraft gains altitude

• Difference in the air pressure at the Venturi throat and the air inlet

• Increase in air velocity in the throat of a Venturi causing an increase in air pressure
