CL650 - Limitations (must know)

Question 1

Maximum fuel load for pressure fueling?

Answer 1

• 20,000 lbs

Question 2

Maximum operating altitude?

Answer 2

• 41,000 ft

Question 3

Maximum weight for landing?

Answer 3

• 38,000 lbs

​

Question 4

If operating on ground, when & what anti-ice systems used (MISTT)?

Answer 4

• If MISTT: Moisture visible (rain, snow or visibility < 1 sm) or ICING detected by ice detection system or operating on Surfaces that are contaminated:
  
  • Temperature ≤ 10°C:
    
    • WING - OFF
    • L & R COWL - ON
  • Temperature ≤ 5°C:
    
    • WING - NORM (NORM for taxi, then turn OFF for T/O if icing conditions don’t exist. If Type II, III or IV fluids applied, then NORM just prior to increasing thrust for takeoff).
    • L & R COWL - ON

IMPORTANT: If engine cowl or wing anti-ice systems are selected On, close the bleed air 10th stage valves for takeoff and landing.
NOTE: Bombardier has so many issues with the aircraft and contaminated wings that they (liability) throw many limitations at the plane to ensure before pitch changes that the leading edges are clean.

Question 5

Maximum speed for turbulent air penetration speed (V_TURB)?

Answer 5

• 280 kts / .75 M

Note: Max speed for starting APU is 290 kts (no Mach speed).

Question 6

Answer 6

• 20,000 ft (this includes electrical: APU GEN - ON)

Note: Bleed Air < 15,000 ft.

Question 7

Maximum altitude for APU bleed air use?

Answer 7

• 15,000 ft

​(bleed air use = 15k’, extend flaps = 15.5k)

Question 8

If operating inflight, when & what anti-ice systems used (MITAA)?

Answer 8

• If MITAA: Moisture visible (rain, snow or visibility < 1 sm) or ICING detected by ice detection system and Temperature ≤ 10°C:
  
  • Altitude < 22,000 ft:
    
    • WING - NORM (regardless of “visible moisture”, prior to extending flaps for approach, it’s required to preheat wings).
    • L & R COWL - ON
  • Altitude ≥ 22,000 ft and the ice detection system failed:
    
    • WING - NORM
    • L & R COWL - ON

NOTE: Bombardier has so many issues with the aircraft and contaminated wings that they (liability) throw many limitations at the plane to ensure before pitch changes that the leading edges are clean.

Question 9

​(231 kts / 197 kts / 189 kts)

Question 12

Maximum transient oil pressure after cold start (2)?

Answer 12

• 156 psi (130 psi at idle, 10 min maximum)

Note: operate engine at idle until oil pressure returns to normal.

Question 13

Maximum fuel imbalance for taxi, takeoff and landing?

Answer 13

• 400 lbs

Question 14

Maximum crosswinds for contaminated runway conditions (2)?

Answer 14

• Fair/Medium: 15 kts (somewhat degraded braking)
• Poor: 10 kts (very degraded braking)

(Good, Fair, Poor, Nil)

NOTE: Normal maximum crosswind (wet or dry) is 24 kts.

Question 15

When do you NOT illuminate Landing Lights (L-Nose-R)?

Answer 15

• When on the ground, except for takeoff or landing.

Do not illuminate RECOG TAXI LTS while the aircraft is not moving. These should be used for taxi, not the Landing Lights.

(limit does not apply to LED bulbs)

Question 16

Maximum start attempts for the APU?

Answer 16

• 3 attempts in 1 hour

Question 17

Maximum speed to start & operate APU?

Answer 17

• 290 KIAS

Note: Similar speed for turbulent air penetration speed = 280 kts / 0.75 M.

Question 18

Maximum speed to extend flaps 45° (V_FE)?

Answer 18

• 189 kts

​(231 kts / 197 kts / 189 kts)

Question 19

Maximum altitude to extend flaps?

Answer 19

• 15,500 ft

​​(bleed air use = 15k’, extend flaps = 15.5k)

Question 20

Minimum altitude for A/P on a steep ILS (GS > 3.5° to 4.5°)?

Answer 20

• 160 ft AGL

Question 21

Minimum battery voltage for engine start or APU start?

Answer 21

• 22 volts

Question 22

Maximum speed to extend flaps 20° (V_FE)?

Answer 22

• 231 kts

​(231 kts / 197 kts / 189 kts)

Question 23

Maximum fuel imbalance for inflight?

Answer 23

• 800 lbs

Question 24

When do you NOT illuminate RECOG TAXI LTS?

Answer 24

• Do not illuminate the RECOG TAXI LTS (switch to right of LANDING LTS) when the aircraft is not moving.

Note: Do not illuminate the LANDING LTS on the ground except for takeoff or landing. On receipt of “line up and wait” clearance = LANDING LTS - NOSE + A/COLL. On receipt of takeoff clearance = LANDING LTS - L & R LANDING).
