CONTACT (FINAL) FOR CT-4E ชุดที่ 3

An angle of attack decrease in straight and level flight is accompanied by:

• A decrease in the total reaction and an aft movement of the centre of pressure.

• A decrease in the total reaction and an forward movement of the centre of pressure.

• A increases in the total reaction and an aft movement of the centre of pressure.

• An aft movement in the total reaction and no change in the centre of pressure.

Indicate stall speed is effected by:

• Load factor, angle of attack and power

• Angle of attack, weight and air density

• Weight, load factor and power

• Weight, load factor and angle of attack

An air traffic control service provide for the purpose of:

• Preventing collisions, expediting and maintaining and orderly flow of air traffic.

• Giving advice and in formation useful for the safe and efficient conduct of flight.

• Providing advice to all aircraft in flight and maintaining an orderly flow of air traffic.

• Expediting of air traffic and recording all aircraft movement.

Excessively high engine temperatures, either in the air or the ground, 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 in either environment.

• Increase fuel consumption and may increase power due to the increase.

1. What effect dose high density altitude have on aircraft performance?

• It increases engine performance.

• It reduces climb performance.

• It increases takeoff performance.

What are some characteristic of unstable air?

• Nimbostratus clouds and good surface visibility

• Turbulence and poor surface visibility

• Turbulence and good surface visibility

What effect does flying into a colder air mass have on airspeed and true altitude if the airplane maintains a constant pressure altitude and CAS?

• Lower true airspeed and lower true altitude

• Higher true airspeed and higher true altitude

• Higher true airspeed and lower true altitude

Where does wind shear occur?

• Exclusively in thunderstorm.

• Wherever there is an abrupt decrease in pressure and/or temperature.

• With either a wind shift or a wind speed gradient at any level in the atmosphere.

The body of a Terminal Aerodrome Forecast (TAF) covers a geographical proximity within a

• 5 statute mile radius from the center of an airport runway complex

• 5 nautical mile radius of the center of an airport

• 5 to 10 statute mile radius from the center of an airport runway complex

Variation is:

• The angle between true north and magnetic north use true north as reference line.

• The angle between magnetic north and compass north use magnetic north as reference line.

• The angle between true north and compass north.

• The angle between magnetic north and true north.
