AVIT 323 BLOCK 2 COMPREHENSIVE STUDY
GUIDE 2026
◉ What are the two types of drag?
Answer: Induced drag and Parasite Drag
◉ What is a sphere of influence?
Answer: Airflow that is affected by the wing
◉ What happens to induced drag as aspect ratio goes up?
Answer: Decreases
High aspect ratio changes the airflow minimally
◉ What happens to induced drag as weight goes up?
Answer: 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?
Answer: Decreases by the square
, Induced drag varies inversely as the square of airspeed
◉ What happens to induced drag when you double the airspeed?
Answer: 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?
Answer: It increases... The induced drag multiplies by 4
◉ What happens to induced drag as altitude goes up?
Answer: Increases
◉ Why are wingtip vortices included in induced drag?
Answer: 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
Answer: Resistance to shear
