Quick Turnaround Limit Weight - Category N Carbon Brakes
Flaps 40
Increase weight by 600 kg per 1% uphill slope. Decrease weight by 1150 kg per 1% downhill slope.
Increase weight by 1550 kg per 10 knots headwind. Decrease weight by 8150 kg per 10 knots tailwind.
After landing at weights exceeding those shown above, adjusted for slope and wind, wait at least 48 minutes
and check that wheel thermal plugs have not melted before executing a takeoff.
If a Brake Temperature Monitoring System (BTMS) is installed:
No sooner than 10 and no later than 15 minutes after parking, check the BRAKE TEMP light. If the BRAKE
TEMP light is not on, no ground waiting period is required. If the BRAKE TEMP light is on, do not dispatch
until at least 48 minutes after landing, or until all the BTMS readings on the systems Display are below 3.0
and the BRAKE TEMP light is off. Check that wheel thermal plugs have not melted before making a
subsequent takeoff.
Note: If any brake temperature display digit is blank or indicates 0.0 or 0.1, then this method cannot be used.
