Normal Configuration Landing Distance
Tables are provided as advisory information for normal configuration
landing distances on dry runways and runways with good, good to medium,
medium, medium to poor, and poor reported braking action. Landing
distances (reference distances plus adjustments) are 115% of the actual
landing distance. The Normal Configuration Landing Distance tables
should be used enroute to make a landing distance assessment for time of
arrival.
The reference landing distance is the distance from threshold to complete
stop. It includes an air distance allowance from threshold to touchdown
associated with a flare time of 7 seconds. The reference distance is based
on a reference landing weight and speed at sea level, standard day, zero
wind, zero slope, two engine detent No. 2 reverse thrust, and auto or
manual speedbrakes.
To use these tables, determine the reference landing distance for the
selected braking configuration and reported braking action. Adjust this
reference distance for landing weight, altitude, wind, slope, temperature,
approach speed, and the number of operative thrust reversers. Each
correction is applied independently to the reference landing distance.
Use of the autobrake system commands the airplane to a constant
deceleration rate. In some conditions, such as a runway with "poor"
reported braking action, the airplane may not be able to achieve these
deceleration rates. In these cases, runway slope and inoperative reversers
influence the stopping distance. It cannot be determined quickly when this
will become a factor, therefore it is appropriate to add the effects of slope
and inoperative reversers when using the autobrake system.
Non-Normal Configuration Landing Distance
Advisory information is provided to support non-normal configurations
that affect landing. Landing distances and adjustments are provided for dry
runways and runways with good, good-to-medium, medium,
medium-to-poor, and poor reported braking action. Landing distances
(reference distances plus adjustments) are representative of the actual
landing distance, and are not factored. The Non-Normal Configuration
Landing Distance tables should be used enroute to make a landing distance
assessment for time of arrival.
The reference landing distance is the distance from threshold to complete
stop. It includes an air distance allowance from threshold to touchdown
associated with a flare time of 7 seconds. The reference distance is based
on a reference landing weight and speed at sea level, standard day, zero
wind, zero slope, and maximum available reverse thrust.
