Exam 2025/2026 Exam Questions and
Correct Answers | New Update
Why does increasing speed also increase lift? - 🧠ANSWER ✔✔The
increased impact of the relatve wind on an airfoils lower surface creates a
greater amount of air being deflected downward.
Adverse yaw during a turn entry is caused by - 🧠ANSWER ✔✔decreased
induced drag on the lowered wing and increased induced drag on the
raised wing
When rolling out of a steep-banked turn, what causes the lowered aileron
to create more drag than when rolling into a turn? - 🧠ANSWER ✔✔The
wings angle of attack is greater as the rollout is started.
Which statement is true concerning the aerodynamic conditions which
occur during a spin? - 🧠ANSWER ✔✔After a full stall, the wing that dips
continues in a stalled condition while the rising wing regains and continues
to produce some lift, causing the rotation.

, Lift produced by an airfoil is the net force developed perpendicular to the -
🧠ANSWER ✔✔relative wind
The angle between the chord line of an airfoil and the relative wind is
known as the angle of - 🧠ANSWER ✔✔attack
Which statement relates to Bernoulli's principal? - 🧠ANSWER ✔✔Air
traveling faster over the curved upper surface of an airfoil causes lower
pressure on the top surface.
The portion of the aircraft's total drag created by the production of lift is
called - 🧠ANSWER ✔✔Induced drag and is greatly affected by changes in
airspeed.
The resistance, or skin friction, due to the viscosity of the air as it passes
along the surface of a wing is called - 🧠ANSWER ✔✔Profile drag.
Changes in the center of pressure of a wing affect the aircraft's -
🧠ANSWER ✔✔aerodynamic balance and controllability
The angle of attack of a wing directly controls the - 🧠ANSWER
✔✔distribution of pressures acting on the wing.
