Limits

Question 1

EGT

Answer 1

Ground:
Start - 925* (845)
Military/afterburner - 630-650

Flight:
Start - 925*
Military/afterburner - 630-650

*abort start if EGT reaches 845. Abort aircraft during ground start if EGT exceeds 925 momentarily

Total fluctuations of +- 7.5 are acceptable if the average EGT is between 630-650

Question 2

RPM

Answer 2

Ground:

Idle - 46-50
Mil/AB - 99-101

Flight:

Mil/AB - 99-104

Fluctuation:

Idle (ground) - 46-50
Mil/AB (ground) - 99-101
Mil/AB (flight) - +- 1

*Max allowable transient RPM 107

Question 3

Nozzle Position

Answer 3

Ground:

Idle - 77-92
Mil - 0-20
Max/AB - 50-85

Flight:

Mil - 0-20
Max/AB - 50-85

Fluctuation limits:

Idle - none
Mil/AB (both) - +-3

*following rapid throttle movements, nozzle position should stabilise within 10 seconds

Takeoff should be aborted if afterburner fails to light within 5 seconds or the light off is abnormal

Question 4

Fuel Flow

Answer 4

Ground:

Start - 360 (max)
Idle - 400-600 (stnd day)
Mil - 2100-2700 (sea level)

Flight:

Start - 360
Idle - 200 (min)

Fluctuation:

Idle (ground) - +-25
Mil/AB (both) - +-50

*during start, ff may momentarily transit above 360 after advancing the throttle to idle during start sequence, but should return to < 360 prior to EGT rise

Question 5

Oil Pressure

Answer 5

Ground:

Idle - 5-20
Mil/AB - 20-55

Flight:

Idle - 5 (min)
Mil/AB - 20-55

Fluctuations:

All: +-2

*do not advance throttle above idle without a positive oil pressure.
*During cold weather, oil pressure may exceed limitation-normal if pressure decreases as temp rises.
*do not exceed 5 mins in mil power with oil pressure >55.
*if a sudden change of 10 psi occurs at any stabilised RPM, follow engine oil malfunctions procedures
*Normal oil consumption should not exceed 6 ounces per hour

Question 6

Airspeed

Answer 6

Flaps 1-45% - 300
Flaps 46-60% - 240
Flaps >60% - 220

Canopy - 50
Relative wind-30

Gear/Gear Doors - 240

NSW - 65 GS

Nose wheel tyre - 174

Zero G 10 seconds
Neg G 30 seconds

Question 7

Load Factor

Answer 7

Fuel / Symmetric / Assymetric

3500 / -2.3 - 5.7 / 0-4.1
3000 / -2.4 - 5.9 / 0-4.3
2000 / -2.6 - 6.5 / 0-4.7
1000 / -2.9 - 7.2 / 0-5

900 Max: -3.0 - 7.33

Extension/retraction of gear at bank angles >45 or above 1.5G can result in overstress or failure of the MLG sidebrace trunnion

Question 8

Hydraulic Pressure

Answer 8

Min: 1500
Max: 3200

Normal: 2850-3200

Question 9

Oxygen Pressure

Answer 9

50-120 PSI

Question 10

DASH 1 - Prohibited Manoeuvres

Answer 10

Vertical Stalls
Intentional Spins
Continuous aileron rolls at other than 1g and/or greater than 3/4 stick deflection

Question 11

Time Limits

Answer 11

MIL power steady state

Ground: 5 min
Flight: 30 min

MAX power steady state

Ground: 5 min
Flight: 15 min

590fpm normal
395fpm crab

Full fuel

340fpm normal
200fpm crab

Question 13

Fuel Balance

Answer 13
