Answer 4

500 kg

Question 5

After a LMC it is mandatory to check the following:

Answer 5

1. ZFW, TOW and LW limits are not exceeded (Structural and Performance);
2. Take-off performance calculations are validated using the revised TOW and TOWOCG;
3. Loading limitations are not exceeded.

Question 6

What should be done if the LMC is greater than 500 kg?

Answer 6

• New ACARS or computer loadsheet required;
• In case of a manual loadsheet, ament loadsheet figures and issue a new trim sheet.

Question 7

Taxi fuel consumption:

Answer 7

2400 kgs/hr (rule of thumb)

Question 8

Maximum taxi speed

Answer 8

• 30 kts
• 10 kts - for slippery surface

Crew may exceed these limits when backtracking on an active runway.

Question 9

Minimum width of runway

Answer 9

45 meters.

Unless a specific airport risk assessment has been carried out and reflected in either the CCI page or a briefing package, where applicable.

For contaminated runways: 30 meters

Question 10

Aircraft ICAO and FAA codes for Taxi limitations

Answer 10

• ICAO: E
• FAA: V

Question 11

Best Rate of Climb Speed

Answer 11

• Flaps UP maneuver speed + 60 knots until intercepting M .82; or
• Vref 30 + 140 knots

Question 12

Best Angle of Climb Speed

Answer 12

On VNAV CLIMB page of the FMC

Question 13

Aircraft Approach Categories

Answer 13

777-200 - C (D for circling)

777-300ER & 777-F - D

Question 14

Standby Fuel

Answer 14

3 tons below flight plan fuel

Question 15

APU Fuel Burn

Answer 15

• Ground Consumption - 240 kg/hour;
• In-flight Consumption - +2.5% for the APU Door being open and 90 kg/hour.

Question 16

Fuel Uplift Check

Answer 16

• Actual Uplift - Calculated Uplift = Uplift Difference (Tolerence +2.000kg, -1.000kg)
• Uplift Difference : Calculated Uplift = % Difference Tolerance ±5%

Question 17

Jettison Rates

Answer 17

• Center Tank Fuel - 2,500 kg/min
• No Center Tank Fuel - 1,400 kg/min
• 2/3 of Jettison Fuel = Time in minutes (Rule of Thumb)

Question 18

Maximum Tire Speed

Answer 18

Takeoff - 204 knots

Landing - 226 knots
