POF Q6 - Aeroplane Axes and the Wing

Question 1

Calculate the tip chord of a wing with a taper ratio of 0.5 and a root chord of 10 metres.

a.10 metres

b.5 Metres

c.25 metres

d.2.5 metres

Answer 1

b.5 Metres

Taper ratio = Tip chord / Root chord

Therefore; Tip chord = Taper ratio x root chord

Tip chord = 0.5 x 10
Tip chord = 5

Question 2

At the wing root, the rigging angle is equal to which other angle?

a.The angle of incidence

b.The chord line angle.

c.The angle of attack

d.The angle of climb

Answer 2

a.The angle of incidence

Question 3

The gross wing area does not include the fuselage.

Select one:
True
False

Answer 3

False

Question 4

Which axis does an aircraft yaw about?

a.Longitudinal Axis

b.Lateral Axis

c.Vertical Axis

d.Normal Axis

Answer 4

d.Normal Axis

Question 5

What is the slight twist given to wings in order to reduce angle of incidence called?

a.Dihedral

b.Anhedral

c.Sweep Angle

d.Washout

Answer 5

d.Washout
