Traffic Pattern Stalls and Hazards

Question 1

What are the indications for being slightly fast in the traffic pattern with the gear down?

Answer 1

1. 0.55 AOA
2. Yellow Chevron
3. FPM on top of AOA staple

Question 2

What are the indications for being on speed in the traffic pattern with the gear down?

Answer 2

1. Light buffet
2. Green Donut
3. 0.6 AOA

Question 3

What are the indications for being slightly slow in the traffic pattern with the gear down?

Answer 3

1. 0.65 AOA
2. Red chevron
3. FPM on bottom of staple in HUD

Question 4

What are the indications for being slow in the traffic pattern with the gear down?

Answer 4

1. 0.75 AOA
2. Moderate Buffet
3. Red Chevron only

Question 5

What are the indications for being very slow in the traffic pattern with the gear down and getting a stall warning?

Answer 5

1. DIBI - Definite increase in buffet intensity
2. 0.8 AOA
3. STALL on the HUD

Question 6

What are the indications for being deathly slow in the traffic pattern with the gear down and getting a stall wanring?

Answer 6

1. 1.0 AOA

2. Heavy buffet

Question 7

How does the T-38s symmetric wing affect buffet?

Answer 7

The onset of the buffet occurs much earlier and is more gradual along the AOA curve compared to cambered wings

Question 8

What is an approach to stall generally indicated by?

Answer 8

Low frequency buffet and usually a moderate wing rock

Question 9

How do you recover from a stall?

Answer 9

Simultaneously:

MAX, RELAX, ROLL

Question 10

How do you identify a high sink rate?

Answer 10

More difficult to recognize than a stall:

1. Seat of the pants
2. Check VVI (primary indication)

Question 11

How do you recover from a high sink rate?

Answer 11

1. Backstick pressure as necessary
2. Roll wings level
3. Advance throttles to MAX

Question 12

What can wake turbulence induce?

Answer 12

Roll motions that can result in a stall

Question 13

How many minutes/miles should you allow before takeoff behind a large type aircraft?

Answer 13

2 minutes

Question 14

How many minutes/miles should you allow before takeoff behind a heavy type aircraft?

Answer 14

4 minutes

Question 15

What type of g-limits do you use when flying through jet wash and what is the max for the T38?

Answer 15

Use Asymmetric G-Limits

4.0 G

Question 16

What is Low Level Wind Shear typically associated with?

Answer 16

1. Weather Fronts
2. Thunderstorms
3. Temperature Inversions
4. Surface Obstructions

Question 17

What are the primary hazards of the approach to stall in the T-38?

Answer 17

Large induced drag leads to a rapid loss of airspeed and creates an excessive sink rate and loss of aileron control/effectiveness

Question 18

How do you recover from an APPROACH to stall?

Answer 18

Relax backstick pressure just short of the increase in buffet, roll wings level, throttles to MAX and do not change configurations (flaps included)

Question 19

What potential hazards occur from using the rudder in the traffic pattern?

Answer 19

With the gear down, the rudder can move +/- 30 degrees. At high AOA, the rudder is extremely efficient at rolling the aircraft.

Question 20

What is a cross-control stall?

Answer 20

When applying rudder in one direction and attempting to counteract the rolling motion created by the rudder with opposite aileron, an increase in AOA occurs leading to loss of effectiveness of the ailerons

Question 21

When taking off behind a large or heavy aircraft, how do you adjust your flight path?

Answer 21

Take off before the preceding aircraft and remain above its flight path

Question 22

How can you “avoid” windshear?

Answer 22

Analyze wind information on your MFD
