Limitations and Useful Numbers

Question 1

Runway slope

Maximum Takeoff and Landing Tailwind Component

Maximum Operating Altitude

Maximum Takeoff and Landing Altitude

Answer 1

+/- 2 deg

15 kts

43,100 ft

14,000 ft

Question 2

Severe Turbulent Air Penetration Speed

Answer 2

● 290 KIAS below 25,000 feet

● 310 KIAS/.84 Mach (whichever is lower) at and above 25,000 feet

Question 3

Maximum altitude difference between Captain and First Officer altimeters

Answer 3

Prior to takeoff the maximum allowable difference between Captain’s or First Officer’s altitude display and field elevation is 75 feet.

Question 4

Maximum Landing Weight

Answer 4

Maximum Landing Weight 192,776kg

Question 5

Autopilot Limitations

Answer 5

The autopilot must not be engaged below a minimum engage altitude of 200 feet AGL after takeoff.

Without LAND 2 or LAND 3 annunciated, the autopilot must be disengaged below 135 feet AGL

Question 6

LMO wind limits Take Off and Landing

Answer 6

Headwind 25 knots

Tailwind 15 knots

Crosswind 15 kts (Company Limit)

Question 7

FLCH

Answer 7

Do not use FLCH on final approach below 1,000 feet AAL.

Question 8

Best Rate and Angle of Climb

Answer 8

Rate: CI 0 or Vref 30 + 140 then M0.84
Also max angle + 60

Angle: Min Clean also shown VNAV climb page

Question 9

Fuel Figures

Answer 9

Taxi 1200kg/hr
IA (overhead) 1020kg
IA enroute 900kg
M/A 330

APU 130kg/hr air. 180kg/hr ground

Rough rule divide fuel by 5 to get time in hold for TCTWO or:
Approx 80kg/min for holding at MLW

11 kg/nm. Therefore cruise ESAD X 11 = flight fuel. (Add 5% heavy)

Flight time x 5.5 + 7 = approx fuel. 12hr flight = 73 tonne

Descending straight to 10,000ft as opposed to 14,000 for 80mins uses extra 400kg

Question 10

Max Tyre Speed

Answer 10

204kts normal ops

226kts non-normal ops

Question 11
