Stalling & Spinning

Question 1

Describe the SSR

Answer 1

Carry out SSR if AoA warner or buffet on Final

Simultaneously:

1. Unload to remove the stall
2. Apply full power
3. Roll wings level

Then:

1. Select Airbrake in
2. Climb using max 10 AoA to 5◦NU (strip gauge is primary for stalling)
3. Clean up.

Question 2

Describe the fully developed CF stall

Answer 2

190 KIAS - 10,000ft datum - 7,000ft base

HASLLT, L/O, select CF Select Idle and trim to maintain nose up

Carry out SSR above 7000ft AGL/AMSL

Height loss will be around 900ft.

Question 3

Describe the flapless stall

Answer 3

(190 KIAS - 7,000ft datum - 5,000ft base)

HASLLT Approach Cx (Gear Only)

ToD 190kts - Begin 2.5◦approach

Set 70% RPM and note reduction in speed to threshold speed (VTH)

Simulate carrying out abrupt overshoot, 10.5 AoA warner will sound, increasing at 14 AoA SSR at buffet onset

Question 4

Describe the App Config stall

Answer 4

(190 KIAS - 6,000ft datum - 5,000ft base)

HASLLT Accel Markers on Horizon - 80% RPM Approach Checks (Gear + Half Flap)

Simulate forgetting to increase power for drag, ignore accel markers

Carry out SSR at first sign of approaching stall.

Question 5

Describe the Down Flap Final Turn Stall

Answer 5

(190 KIAS - 6,000ft datum - 5,000ft base)

HASLLT Approach Checks (Gear + Down Flap)

Tip in 45◦AoB Halfway round, increase to >7.5AoA (top of E Bracket) simulating picking up centre line

SSR at first symptom of stall.

Question 6

Describe the spinning height criteria

Answer 6

• Max Entry Height - 30,000ft RPS
• IOT spin, cloud tops cannot be above 15,000ft
• Min Entry Height - 25,000ft RPS (MEH must be 15,000ft above cloud tops)
• MEH only affected if cloud tops above 10,000ft
• Min Height Commence Recovery - 15,000ft MSD
• Min Abandon Height - 5,000ft MSD

Question 7

Describe the SHIFTAS

Answer 7

• Speed - 165 KCAS / 10 AoA (whichever first)
• Height - 25-30,0000ft RPS
• Idle
• Fuel - CL Tank Empty
• T6 - Low and stable
• Ailerons - Neutral
• Spin direction - Same as lookout turn

Question 8

Describe the spin recovery criteria

Answer 8

Recovery should be initiated if any of SHET2 occur:

• Speed - <100 or >200 KIAS
• Height - < 15,000 ft MSD
• Excessive Side forces
• T6 - Significant rise
• 2 Turns

On entry, and after every turn call height (Height) - speed 100-200 (Height) - T6 stable, no excessive side forces (Height) - Idle, centralise

Question 9

Describe the full spin entry

Answer 9

Question 10

Describe the full spin entry (2)

Answer 10

Question 11

Describe the spin recovery

Answer 11

1. Check Height above MHCR (15,000ft)
2. Throttle Idle (whilst smoothly centralising)

When the spin stops:

1. CF Out
2. 100 KIAS, wings level
3. 150 KIAS, pull to light buffet to level (3.5G)
4. Check engine for surge (check CWP and open throttle to full)
5. Check instruments and orientate yourself
