Quick question, WHAT IS THE CROSSWING LANDING LIMITS OF AN A320.

wind currently straight across the runway at 20 Gusting 32 knots. Would a320 make an attempt to land in this or is it below/close to crosswind landing limit??????

Wind for takeoff and landing :

Maximum crosswind demonstrated for takeoff 29 knots gusting up to 38 knots*

Maximum crosswind demonstrated for landing 33 knots gusting up to 38 knots*

Maximum tailwind 10 knots

* : Maximum crosswind values have been demonstrated with flight controls in normal law, as well as in direct law with and without yaw damper.

But then there is also this to consider:

To optimize directional control during the low speed phase of the takeoff and landing roll and according to the reported braking action given by the control tower, it is not recommended to take off or to land with a crosswind component higher than :


Reported braking action Reported runway friction coefficient Maximum crosswind (kt):
Takeoff Landing Equivalent runway condition **
Good >= 0.4 29 * 33 * 1
Good/medium 0.39 to 0.36 29 29 1
Medium 0.35 to 0.3 25 2/3
Medium/poor 0.29 to 0.26 20 2/3
Poor <= 0.25 15 3/4
Unreliable 5 4/5
* This is the maximum crosswind demonstrated for dry and wet runway.
** Equivalent runway condition (only valid for maximum crosswind determination)
1. Dry, damp or wet runway (less than 3 mm water depth)
2. Runway covered with slush
3. Runway covered with dry snow
4. Runway covered with standing water with risk of hydroplaning or wet snow
5. Icy runway or high risk of hydroplaning

Not forgetting that if you intend to fly a Cat II or Cat III autoland then crosswind limits decrease to 25kts and 20kts respectively

A320 crosswind limit is 38kts, gust included.

this guy doesn't seem to mind those limits

For manual landings there are no crosswind limits given in the AFM for the A320 (like for most aircraft). It's up to the operator to define limits (if they want). Often the demonstrated crosswinds are used as limits. It is my experience that many operators do struggle with this topic.
