Level 4 Air Cadet Aviation Exam questions and answers 100% verified. 25 - correct answers.The thickest part of the conventional airfoil occurs at __% of the chord. 50 - correct answers.The thickest part of a laminar flow airfoil occurs at __% of the chord. Boundary Layer - correct answers.The very thin layer of air lying over the surface of the wing. Laminar Layer - correct answers.The area at the front of the wing where air flows smoothly over the surface. Turbulent Layer - correct answers.The area further along the wing where air slows down due to friction and becomes turbulent. Transition Point - correct answers.The point where laminar flow changes to turbulent flow. Aspect Ratio - correct answers.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 answers.The angle at which the wing is permanently inclined to the longitudinal axis of the wing. Wash-Out - correct answers.Decrease of the angle of incidence at the wingtip. (ex. Installing wingtip fuel tanks, using winglets, drooping the wingtips, etc.) Wash-In - correct answers.Increase of the angle of incidence at the wingtip. (ex. Installing wingtip fuel tanks, using winglets, drooping the wingtips, etc.) Slats - correct answers.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 answers.Auxiliary airfoils that DO NOT move, they are passageways built in the wing, but serve the same purpose as slats. Pitot Pressure - correct answers.The increase in air pressure caused by the forward motion of the aircraft through the air. Static Pressure - correct answers.The atmospheric pressure outside of the aircraft, not affected by motion or turbulence. Altimeter and Vertical Speed Indicator - correct answers.Relies exclusively on static pressure. Airspeed Indicator - correct answers.Relies on both pitot and static pressure. (hint: ASI) Red - correct answers.Never Exceed Speed (Altimeter colour indication). Yellow - correct answers.Caution Range (Altimeter colour indication). Green - correct answers.Normal Operating Range (Airspeed colour indication). White - correct answers.Range that fully extended flaps may be used (Airspeed colour indication). Density Error - correct answers.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 answers.Uncorrected airspeed as read from the ASI (hint: IAS). Calibrated Airspeed - correct answers.IAS corrected for position error (hint: CAS). Equivalent Airspeed - correct answers.CAS corrected for compressibility (hint: EAS). True Airspeed - correct answers.EAS corrected for density (hint: TAS). Altimeter - correct answers.Indicates altitude of aircraft.
