,Section A - Aerodynamics OF LIFT
Q1.
A jet aircraft is cruising at a given altitude. If the pilot increases speed from the minimum
drag speed to a higher speed while maintaining level flight, what happens to the total drag
and the lift-to-drag ratio?
A. Total drag decreases and L/D increases. B. Total drag increases and L/D decreases.
C. Total drag increases and L/D increases. D. Total drag decreases and L/D decreases.
Correct: B - Total drag increases and L/D decreases.
Rationale:In the typical drag vs. speed curve, the minimum drag speed (Vmd) corresponds to
the maximum L/D. Increasing speed beyond Vmd increases total drag (due to parasite drag)
and decreases L/D because the lift-to-drag ratio is maximized at Vmd.
Why the other answers are wrong:
A. This would be true if moving toward Vmd from a slower speed, but moving away increases
drag.
C. L/D cannot increase beyond its maximum at Vmd.
D. Drag does not decrease when moving away from Vmd.

Q2.
An aircraft experiences a sudden stall at a high angle of attack. Which statement best
describes the sequence of events at the wing's upper surface?
A. The boundary layer transitions from B. The adverse pressure gradient causes
laminar to turbulent, then separates near the the boundary layer to separate, leading to a
trailing edge. loss of lift.
C. The flow accelerates over the upper D. The boundary layer thickens and
surface, increasing lift until the wing breaks. reattaches, causing a pitch oscillation.
Correct: B - The adverse pressure gradient causes the boundary layer to separate, leading
to a loss of lift.
Rationale:Stall occurs when the adverse pressure gradient on the upper surface becomes
too steep, causing the boundary layer to separate from the wing. This separation leads to a
loss of lift and an increase in drag.
Why the other answers are wrong:
A. Transition to turbulent flow is not the cause; separation is.
C. Flow acceleration alone does not cause stall; it is the separation that does.
D. Reattachment would not cause a stall; it would restore lift.

Q3.
In a steady level turn, an aircraft's induced drag increases. Which factor contributes most
significantly to this increase?
A. Increased wingtip vortices due to higher B. Decreased aspect ratio from wing sweep.
angle of attack.
C. Increased parasite drag from higher D. Reduced air density at higher altitudes.
airspeed.
Correct: A - Increased wingtip vortices due to higher angle of attack.
Rationale:In a level turn, the wing must generate more lift to balance weight and centripetal
force, increasing the angle of attack. This strengthens wingtip vortices, which increases
induced drag.
Why the other answers are wrong:
B. Aspect ratio does not change during a turn.
C. Parasite drag may change with speed, but induced drag is the primary increase.
D. Air density affects both, but not the specific increase in induced drag.

Q4.
A wing is designed with a high aspect ratio. How does this affect the lift-induced drag
coefficient (CDi) compared to a low aspect ratio wing at the same lift coefficient?
A. CDi is lower because induced angle of B. CDi is higher because of increased
attack is smaller. wingtip vortices.
C. CDi is unaffected by aspect ratio. D. CDi is higher because of increased
wetted area.
Correct: A - CDi is lower because induced angle of attack is smaller.
Rationale:Induced drag coefficient is inversely proportional to aspect ratio: CDi = CL^2 / (À *
AR * e). A higher aspect ratio reduces the induced angle of attack and thus the induced drag.
Why the other answers are wrong:
B. Higher aspect ratio actually reduces wingtip vortices.
C. Aspect ratio is a direct factor in CDi.
D. Wetted area affects parasite drag, not induced drag.
