AA1211 TP Stalls and Sinks

Question 1

What AOA corresponds to the green donut

Answer 1

approx 0.6

Question 2

What are the two main hazards of approach to stall characteristics

Answer 2

“very large induced drag caused by the large increase in lift. This extra drag will result in a thrust deficiency and thus loss of airspeed and high sink rate.
The second is loss of aileron effectiveness. “

Question 3

At optimum AOA the aircraft buffet is

Answer 3

high frequency, low intensity

Question 4

AOA slightly higher than optimum is characterized by

Answer 4

lower frequency,slightly higher intensity

Question 5

At high AOA (0.8), the buffet is characterized by

Answer 5

definite decrease in frequency, definite increase in intensity

Question 6

At stall AOA, what indications can happen

Answer 6

wing rock and extreme descent rates

Question 7

Recovery actions for approach to stall indications

Answer 7

Max, Relax, Roll

Question 8

During the Relax phase of Max, Relax, Roll, how should the back stick pressure be “relaxed”

Answer 8

reduced to “a buffet level just short of the definite increase in buffet intensity”

Question 9

When doing real recoveries from stall, when is the gear raised

Answer 9

when safely flying and not going to touchdown

Question 10

Should you move the flaps during a recovery (real or practice)

Answer 10

No

Question 11

What are the recovery actions when excessive sink rates have developed

Answer 11

Max, Maintain buffet level just short of apprach to stall, Roll

Question 12

If you get to the perch point and you know you are too tight what do you do

Answer 12

break out

Question 13

If you realize you are too tight after you perch what do you do

Answer 13

continue the turn into a go-around

Question 14

What is the most common error leading to airspeed deviations on final

Answer 14

not pulling power after the final turn which leads to getting fast

Question 15

does the landing attitude or takeoff attitude have a higher pitch

Answer 15

Landing

Question 16

How do you correct for a sinking flare (higher than normal VVI)

Answer 16

Go-Around

Question 17

If you get into a high flare, what should you not do in any case

Answer 17

Increase pitch

Question 18

What problems make the T-38 susceptible to wake turbulance

Answer 18

small wingspan(easier to be engulfed by votrices), traffic pattern speed (may not be able to slow enough to create spacing behind slower traffic) and landing distance (can’t touchdown after an aircraft if the whole runway is required to land)
