AVIT 323 Block 2 Exam Questions and
Answers 100% Pass
What is induced drag? - ✔✔The aft-acting component of lift
What are the two types of drag? - ✔✔Induced drag and Parasite Drag
What is a sphere of influence? - ✔✔Airflow that is affected by the wing
What happens to induced drag as aspect ratio goes up? - ✔✔Decreases
High aspect ratio changes the airflow minimally
What happens to induced drag as weight goes up? - ✔✔Increases by the square
If lift (or weight) doubles, induced drag is 4 times as great.
What happens to induced drag as speed goes up? - ✔✔Decreases by the square
Induced drag varies inversely as the square of airspeed

, What happens to induced drag when you double the airspeed? - ✔✔It decreases
The induced drag reduces to 1/4 the amount as before
What happens to induced drag when you cut the airspeed in half? - ✔✔It increases...
The induced drag multiplies by 4
What happens to induced drag as altitude goes up? - ✔✔Increases
Why are wingtip vortices included in induced drag? - ✔✔Induced drag can be found
when wingtip vortices are formed because they reduce the wing's ability to create lift
and increases the drag force acting on the aircraft
Define Viscosity - ✔✔Resistance to shear
What are the types of Parasite Drag? - ✔✔Form Drag/Pressure Drag
Skin Friction Drag/Viscous
Profile Drag
Interference Drag
Cooling Drag
Leakage
