AVIT 323 BLOCK 9 EXPECTED QUESTIONS WITH
VERIFIED ANSWERS
Question 1.
What creates the forward stagnation point?
ANSWER
The local velocity is zero and the maximum positive pressure results
Question 2.
Why do we not feel the spiraling slip stream at faster airspeeds?
ANSWER
The neutral buoyancy point is pushed backwards
Question 3.
What is gyroscopic precession?
ANSWER
It shows up anytime you change the angle of a disc (the propeller). It is very prominent in
tail wheel aircraft and can be a left or right turning tendency.
Question 4.
What finesse value do transport category aircraft aim to have?
ANSWER
15
,Question 5.
Draw a gliding plane and label:
Lift
Weight
Airspeed
Horizontal Plane
Drag
Rate of descent
Vertical lift
ANSWER
Question 6.
Draw these components on an airfoil:
Forward stagnation point
Mean camber line
Chord line
Maximum change in airflow velocity
Adverse pressure gradient
ANSWER
Question 7.
What is the relationship of weight and L/Dmax speed?
ANSWER
Higher the weight = the higher the L/Dmax speed
, Question 8.
What is the archer lift surface area?
ANSWER
174 ft^2
Question 9.
What two things cause overbanking tendencies?
ANSWER
1) The difference in lift created by the difference in speeds between the outside and inside
wing makes the outboard wing want to raise more and thus, roll more
2) The lateral component of lift on the upward wing is greater than the vertical component of
lift on the lowered wing
Question 10.
What left turning tendencies show up during a Chandelle?
ANSWER
all of them
Question 11.
What is the most common cause of an unintentional spin?
ANSWER
Side slip from a stall
Question 12.
What are slots?
ANSWER
Slots are permanent pathways through the wing which allow air to flow from the lower
surface to the upper wing to energize the boundary layer. They help to maintain aileron
authority at lower airspeeds and increase the critical AOA and Cl
