LEVEL 4 AIR CADET AVIATION EXAM QUESTIONS AND ANSWERS
25 - CORRECT ANSWER✅✅The thickest part of the conventional airfoil occurs at __% of the chord.
50 - CORRECT ANSWER✅✅The thickest part of a laminar flow airfoil occurs at __% of the chord.
Boundary Layer - CORRECT ANSWER✅✅The very thin layer of air lying over the surface of the wing.
Laminar Layer - CORRECT ANSWER✅✅The area at the front of the wing where air flows smoothly over
the surface.
Turbulent Layer - CORRECT ANSWER✅✅The area further along the wing where air slows down due to
friction and becomes turbulent.
Transition Point - CORRECT ANSWER✅✅The point where laminar flow changes to turbulent flow.
Aspect Ratio - CORRECT ANSWER✅✅The relationship between the length of the wing and its width,
calculated by dividing the wingspan by the average chord (Leading edge to trailing edge).
Angle of Incidence - CORRECT ANSWER✅✅The angle at which the wing is permanently inclined to the
longitudinal axis of the wing.
Wash-Out - CORRECT ANSWER✅✅Decrease of the angle of incidence at the wingtip. (ex. Installing
wingtip fuel tanks, using winglets, drooping the wingtips, etc.)
Wash-In - CORRECT ANSWER✅✅Increase of the angle of incidence at the wingtip. (ex. Installing wingtip
fuel tanks, using winglets, drooping the wingtips, etc.)
Slats - CORRECT ANSWER✅✅Auxiliary airfoils that automatically move out in front of the leading edge
of the wing at high angles of attack, to improve low speed stability/handling.
, Slots - CORRECT ANSWER✅✅Auxiliary airfoils that DO NOT move, they are passageways built in the
wing, but serve the same purpose as slats.
Pitot Pressure - CORRECT ANSWER✅✅The increase in air pressure caused by the forward motion of the
aircraft through the air.
Static Pressure - CORRECT ANSWER✅✅The atmospheric pressure outside of the aircraft, not affected
by motion or turbulence.
Altimeter and Vertical Speed Indicator - CORRECT ANSWER✅✅Relies exclusively on static pressure.
Airspeed Indicator - CORRECT ANSWER✅✅Relies on both pitot and static pressure. (hint: ASI)
Red - CORRECT ANSWER✅✅Never Exceed Speed (Altimeter colour indication).
Yellow - CORRECT ANSWER✅✅Caution Range (Altimeter colour indication).
Green - CORRECT ANSWER✅✅Normal Operating Range (Airspeed colour indication).
White - CORRECT ANSWER✅✅Range that fully extended flaps may be used (Airspeed colour
indication).
Density Error - CORRECT ANSWER✅✅Temperature and pressure normally decrease when increasing
altitude, decreasing the density of air and causing the ASI to read less than true airspeed. This is called:
_______ _____.
Indicated Airspeed - CORRECT ANSWER✅✅Uncorrected airspeed as read from the ASI (hint: IAS).
Calibrated Airspeed - CORRECT ANSWER✅✅IAS corrected for position error (hint: CAS).
