Limitations

Question 1

What is the maximum ITT (TOT) on: (i) start; (ii) take-off; (i i i ) climb; (iv) maximum continuous power; (v) idle; (vi) reverse; (vii) transient;

Answer 1

(i) start; 1090 (2s) (ii) take-off; 805 (5 min) (i i i ) climb; 765 (iv) maximum continuous power; Not Published (v) idle; 680 (vi) reverse; 805 (vii) transient; 850 (2s)

Question 2

Max torque on: (i) take-off; (ii) climb; (iii) maximum continuous power; (iv) idle; (v) reverse; (vi) transient;

Answer 2

(i) take-off; 1865 (ii) climb; 1865 (iii) maximum continuous power; 1865 (iv) idle; NA (v) reverse; 1865 (vi) transient; 2400

Question 3

Max Ng (N1) on take-off,

Answer 3

101.6%

Question 4

What is the minimum inflight power limit?

Answer 4

Flight Idle

Question 5

Starter cycle limitations:

Answer 5

(i) 30 seconds on 1 minutes off (ii) 30 seconds on 1 minutes off (iii) 30 seconds on 30 minutes off 20s on and double rest times for external start

Question 6

What oil pressure illuminates the warning light if fitted?

Answer 6

40psi

Question 7

Before shutdown, the engine must run at or below what ITT?

Answer 7

minimum ITT for one minute.

Question 8

What is the critical/prohibited RPM range and what limitations apply to this range?

Answer 8

Normal range 1600-1900. Transient zone between 1900-2090.

Question 9

What is the auto ignition and when is it used?

Answer 9

Only Ignition settings are Normal and On.

Normal is used for start.

On for air starts without starter assist,

• operation on water-covered runways,
• during flight in heavy precipitation,
• during inadvertent icing encounters until the inertial separator has been in bypass for 5 minutes, and
• when near fuel exhaustion as indicated by illumination of the RESERVOIR FUEL LOW annunciator.

Question 10

What are the settings of the condition lever, and what is the purpose
of each setting?

Answer 10

• CUTOFF position shuts off all fuel to the engine fuel nozzles. (Shutdown)
• LOW IDLE positions the control rod stop to provide an RPM of 52% Ng (Slower taxi speed to High Idle)
• HlGH IDLE positions the control rod stop to provide an RPM of 65% Ng
