.
Preferred runway exit point: potential increase in runway occupancy time and block time.
.
Runway surface conditions: effect on brake efficiency.
.
Tailwinds: effect on landing ground speed and distance.
.
Additional brake cooling time: increase in turn around time.
.
Potential increase in brake and tire wear.
Important Notice
In order to maximize safety margins the

recommends the use of the FULL configuration
for all landings. Nonetheless, where runway

Using idle reverse on landing instead of full reverse will reduce fuel consumption and may benefit the engine.
However, the aircraft’s

must still be dissipated. It may be possible to achieve this over a longer landing distance and thereby limit any increases in brake and tire wear this procedure implies but, in all cases, the operational and economic aspects highlighted in the previous section (Landing Flap Configuration) should be considered for each landing.
Important Notice
In order to maximize safety margins the Airb us FCOM (Flight Crew Operating Manual) recommends the use of maximum thrust reverse for all landings. Nonetheless, where runway length and conditions are favorable reverse idle ma y be considered.
