AVIT 323- Block 10 Test Questions and
Answers 100% Pass
Drag - ✔✔Component of aerodynamic force parallel to relative wind and retards the
motion of the aircraft
Parasite Drag - ✔✔Not associated with lift, displacement of air by aircraft
Induced Drag - ✔✔Drag that results from production of lift
Pressure difference from upper and lower wing surfaces
Shockwave Drag - ✔✔Shockwave formation at high airspeeds
Skin Friction Drag - ✔✔Aerodynamic resistance due to conflict of moving air with
surface of aircraft, does not matter how smooth air surface is
Increase Skin Friction Drag - ✔✔Wetted Surface= airfoil that has direct contact with
atmosphere
Amount of Viscous Drag in Boundary Layer= airflow local reduction due to viscosity

, Velocity
Reduce Skin Friction Drag - ✔✔Flush mounted rivets
Smooth finish
Wax
Form Drag - ✔✔Drag generated by shape of aircraft and components (net force
develops and opposes flight path)
Reduce stream lining (less form drag and increase skin friction)
Profile Drag - ✔✔Result of skin friction and form drag an airfoil creates
Drag Bucket= low AOA, coefficient of drag is reduced/ high AOA produce separation
and increase coefficient of lift
Interference Drag - ✔✔2 airstream that intersect and create turbulence and restrict
smooth air flow
