Three Types Of Stall & etc

Question 1

Changes position on leading edge of wing as stagnation points move. Moves up if stagnation point moves down. Gets pushed up by the wind (up wash)

Answer 1

Flapper switch

Question 2

Rotates around ac longitudinal axis to align itself with the airflow. Vane angle info sent to computer for AOA position.
On side of AC

Answer 2

AOA VANE

Question 3

Distance between two pressures. Pressures in both tubes adapt to point directly into airflow.
If high AOA, wind flow mainly hitting the bottom tube, so high p in bottom tube.

Answer 3

AOA probe

Question 4

Ground effects. What it’s effect on downwash.

Answer 4

Downwash decreases, because vertices can’t fully function

Question 5

ASI

An increase in static pressure going in. Leads to

Answer 5

Under read of instruments

Question 6

Canards promote

With stall

Answer 6

Stall first at canard. Causes pitch down of nose first.

Question 7

Fowler flaps:

Answer 7

Increase surface area.

Increase lift.

Question 8

Slotted Fowler Flaps allow for:

Answer 8

Reenergised boundary layer. = more lift.

Reenergised boundary layer, as in the lower section of the wing, trailing edge

Question 9

Two pressure tubes. If pressure higher in one than other. Than probe rotates in direction of where the high pressure is going into low pressure.
Null is reached when both pressures the same.

Answer 9

Rotating Probe (null seeking probe)

Question 10

EASA stall speed references set in which documents?
Small AC:
Large AC:

Answer 10

CS-23

CS-25

Question 11

VSR may not be ..?.. than 1g stall speed

Answer 11

LESS
