Dry runway
Read from ALD table,
ALD (0 ft, No wind, VLS, no reversers) = 910 m
Read from the Corrections table,
Pressure altitude correction: 3 × 2 = +6 %
Speed increment correction: +8 %
ALD (2 000 ft, No wind, VLS + 5 kt, no reversers) = 910 × 1.06 × 1.08 = 1 050 m.
LANDING DISTANCE WITHOUT AUTOBRAKE - CONF FULL
The actual landing distance is the distance to come to a complete stop from a point 50
ft above the landing
surface. No margin is included in this distance.
