ACTUAL LANDING DISTANCE
The actual landing distance is the distance measured between a point 50 ft above the runway
threshold and the point where the complete stop of the aircraft is achieved.
It assumes that :
‐ the approach speed is :
• VLS (1.23 VS of the configuration) for manual landing
• VLS + 5 kt for CAT II/CAT III automatic landing.
‐ the pilot applies maximum braking and the antiskid system is operating.
‐ the ground spoilers are operating.
It does not consider the use of reverse thrust.
REQUIRED LANDING DISTANCE
MANUAL LANDING
Regulation defines the required landing distance as the actual landing distance divided by 0.6,
assuming the surface is dry.
If the surface is wet, the required landing distance must be at least 115 % of that for a dry
surface.
For JAR-OPS operators, if the surface is contaminated, the required landing distance must be at
least the greater of the required landing distance on wet runway (see previous paragraph) and
115 % of the landing distance determined in accordance with approved contaminated landing
distance data.
AUTOMATIC LANDING
Regulation (JAR.AWO 142) defines the required landing distance for automatic landing as the
actual landing distance in automatic landing multiplied by 1.15. This distance must be retained
for automatic landing whenever it is greater than the required landing distance in manual mode.
DISPATCH
Applicable to: ALL
The pilot must check before departure that the available runway length at destination is at least equal
to the required landing distance for the forecasted landing weight.
In case of aircraft system failure affecting landing distance known before the dispatch, the available
runway length must be at least equal to the required landing distance with failure, i.e. the required
landing distance without failure multiplied by the coefficient given in the Flight Manual or the MMEL.

FAILURE IN FLIGHT
Applicable to: ALL
In case of an aircraft system failure occurring in flight and affecting the landing performance, the
runway length to be considered for landing is the actual landing distance without failure multiplied
by the landing distance coefficient associated with the failure. The coefficients are given in Refer
