LANDING
UNFACTORED LANDING DISTANCES
Unfactored landing distance is the actual distance to land the airplane
on a zero slope, ISA temperature, dry runway from a point 50 ft above
runway threshold at Vref, using only the brakes and spoilers as
deceleration device (i.e., no engine reverse thrust is used).
The required landing distance for dispatch is the unfactored landing
distance increased by the 66.7% for dry runway or 91.7% for wet
runway.
For obtaining the DRY runway factored distance, multiply unfactored
landing distance by 1.667.
For obtaining the WET runway factored distance, multiply unfactored
landing distance by 1.917.
NOTE: The landing distance correction factors mentioned in some
emergency or abnormal procedures must be applied to the flap
45 unfactored landing distance.
