Question 6

ENGINE START (FLIGHT) Max windmilling/starter-assisted cross-bleed relight altitude:

Answer 6

FL210

Question 7

ENGINE WARMUP

Answer 7

Until oil pressure reaches green band: Do not exceed idle Do not exceed 75% N1 until: 2 minutes, or All operating indication

Question 8

Ground Idle N2 Split:

Answer 8

≤2%

Question 9

During 2nd engine APU bleed start:

Answer 9

Operating engine <70%

Question 10

With OAT ≥ –20°C, thrust levers at idle, N2:

Answer 10

>57%* * If N2 is ≤57% with the OAT of -20° C or greater, do not advance thrust levers above idle. Contact Maintenance.

Question 11

Engine must not be shut down until:

Answer 11

2 minutes at idle/near idle thrust NOTE - Taxi time counts towards this limitation.

Question 12

THRUST REVERSER use during taxi

Answer 12

SkyWest prohibits the use of thrust reversers during taxi operations.

Question 13

CRJ 700/900 TAKEOFF THRUST VALUES

Answer 13

With the engines running and bleeds configured for takeoff, the crew must verify the target N1 values correspond with ACARS or TLR data ± 1.0%. When the thrust levers are set for takeoff, target and N1 values must match.
