Aerodynamics and Flight Mechanics Quiz

A Wash-In wing is a wing that is twisted with the angle of incidence:

• Same angle as for both the wing root and wing tip

• Greater at the wing tip than the wing root

• Greater at the wing root than the wing tip

An aircraft having a high aspect ratio wing will be:

• Unstable and less manoeuvrable

• More stable but less manoeuvrable

• Less stable but more manoeuvrable

At what mode of operation are the flight spoilers being deployed simultaneously at both wings?

• ground mode

• roll mode

• speedbrake mode

Centre of gravity of an aeroplane can be determined using a percentage of:

• Mean aerodynamic chord line

• Mean camber line

• Longitudinal axis line

During a coordinated turn or banking, the aeroplane altitude dropped. What should the pilot do to maintain the flight level?

• rotate the control wheel and apply more throttle

• press the applicable rudder pedal and apply less throttle

• pull the control column and apply more throttle

During a right banking, if the aircraft start to reduce its altitude, what can the pilot do to correct it?

• turn the control wheel to the right

• push the right rudder pedal

• pull the control yoke

Dutch roll involves movement of the aeroplane about both the:

• longitudinal and lateral axis

• lateral and vertical axis

• vertical and longitudinal axis

For an aeroplane using power flying control unit (PFCU), the trimming of the primary flight control is through the use of:

• trim actuator

• trim tab

• balance tab

How do slots assist in increasing the lift of an aircraft?

• increasing the area of the wing

• decreasing the camber on the upper wing

• delay airflow separation at high angle of attack

If an aeroplane has a low aspect ratio wings, you can expect the wings to be:

• long and slender

• short and stubby

• slim and narrower
