Question 2

Is it permissible to simultaneously use the APU bleed and HP cart?

Answer 2

NO, Prohibited

Question 3

When should the TO DATA SET MENU on the MCDU be set to ENG?

Answer 3

-When OAT is from 5C to 10C and,
-When there is any possibility of encountering visible moisture up to 1700 ft AFE -When operating on ramps, taxiways, or runways when surface snow, ice,
standing water, or slush may be ingested by the engines, freeze on engines, nacelles, or engine sensor probes.

Question 4

Answer 4

-When OAT is less than 5C and,
-When there is any possibility of encountering visible moisture up to 1700 ft AFE -When operating on ramps, taxiways, or runways where surface snow, ice, standing water, or slush may be ingested by the engines, freeze on engines, nacelles, or engine sensor probes.

Question 5

What is the SOPM definition of “visible moisture”?

Answer 5

Clouds, fog with visibility of one mile or less, rain, snow, sleet, and ice crystals

Question 6

What are the Starter Cranking Limits on the ground?

Answer 6

1 & 2: 90 seconds ON / 10 seconds OFF 3 - 5: 90 seconds ON / 5 minutes OFF

Question 7

What are the Dry Motoring Cycle Limits?

Answer 7

1: 90 seconds ON / 5 minutes OFF 2 -5: 30 seconds ON / 5 minutes OFF

Question 8

During engine start you experience a hung start, what are the indications and what action do you take?

Answer 8

N1 and/or N2 failing to accelerate to stable idle speed (hung start)

AFFECTED ENGINE
START / STOP SELECTOR - STOP (ENGINE ABNORMAL START)

Question 9

What other conditions require aborting a start?

Answer 9

10, 50, 30, HOT, LOP, Hung, EPS

• No positive oil pressure indication within 10 seconds after N2 speed starts to increase.

• During engine start with a tailwind, when a positive increase of N1 is not indicated before starter cutout (50% N2). In this case, the airplane is repositioned prior to engine start to minimize tailwind effects.

• No ITT indication within 30 seconds after initiation of fuel flow (no light off).

• ITT exceeds start limit (815°C - Hot).

• Oil pressure stabilizes below the engine limits.

• N1 and/or N2 failing to accelerate to stable idle speed (hung start).

• An intermittent electrical pneumatic or starter malfunction occurs before the starter disengagement.

Question 10

At idle engine thrust, the engine exhaust danger area can extend to approximately 90 feet
behind the aircraft with a jet blast velocity reaching?

Answer 10

65 mph (SOPM CH 2)
