5000 ft AGL

Question 20

Recovery after

Answer 20

1) 4 Turns
2) CAS increases to 200 kts
3) CAS decreases to 100 kts
4) Large transient side forces
5) Manual rudder - aerodynamic forces to large to hold
6) (TGT > 450 C) engine surge

Question 21

Symmetrical (<13650 lbs) g limits

Answer 21

0 - 500 kts /0.8M = +8 to -4G

500 - 575 KTS/0.8 M - 1.2M = +5 to 0 g

Question 22

G limits with external fuel tanks (>50lbs)

Answer 22

0 - 525 kts/0.8M = 5 to -1 g

0.8 - 0.85 M = 3 to 0 g

Question 23

G limits with empty external tanks (<50 lbs)

Answer 23

0 - 525 kts/0.8M = +6 to -1G

0.885M = +4 to 0 G

Question 24

Jettison (gear/flap up)

Answer 24

Fuel > 515 lbs = <350 kts/ < 10000 ft

Fuel < 515 lbts = 300-350 kts/ < 10,000 ft

Answer 25

1) Flick or snap manoevres
2) Inverted Spinning
3) Stall Turns

Question 26

G limits with flaps extended

Answer 26

1/2, 3/4, Down = +2.5 to 0 G

Combat = +8 to -2G
