AVIT 323 BLOCK 1 MOCK TEST WITH ANSWER
RATIONALES 2026
◉ Planform.
Answer: the shape of the wing viewed from above
◉ Chord Line.
Answer: An imaginary straight line from the leading edge to the
trailing edge of an airfoil.
◉ Leading Edge.
Answer: The part of the airfoil that meets the airflow first.
◉ Trailing Edge.
Answer: The last point on an airfoil that interacts with the airflow
around the wing.
◉ Mean Camber Line.
Answer: An imaginary line between the leading and trailing edges
and halfway between the airfoil's upper (curved) and lower (flat)
surfaces
, ◉ Maximum Camber.
Answer: the maximum distance of the mean camber line from the
chord line
◉ Symmetrical Airfoil.
Answer: An airfoil having the same shape on the top and bottom.
◉ Cambered Airfoil.
Answer: an airfoil that has a curved upper surface and a flat lower
surface
◉ Adverse Pressure Gradient.
Answer: A pressure gradient of increasing static pressure in the
direction of airflow.
◉ Aspect Ratio.
Answer: the wingspan divided by the average chord
◉ Bernoulli's Principle.
Answer: high speed = low pressure
◉ Magnus Effect.
