Crab angle keeps the flight path on the centerline
On approach, the aircraft can point partly into the wind while moving along the runway’s extended centerline. This is called crabbing and may be maintained until close to touchdown.
The aircraft may be de-crabbed before touchdown
Pilots can use rudder to align the fuselage with the runway while applying opposite aileron to control drift. Timing depends on aircraft type, wind strength and operator technique.
Some aircraft allow limited crab at touchdown
Large airliners may tolerate a small crab angle because their landing gear is designed for it, but limits still apply. Excessive side loading can damage tires or gear.
Gusts make control more dynamic
A steady crosswind is easier to predict than a gusty one. Crews account for gust increments and continuously adjust control inputs during the flare and rollout.
Every aircraft has crosswind guidance or limits
Manufacturers publish demonstrated crosswind values and operators may impose stricter limits. Runway contamination can reduce the allowable crosswind because directional control becomes more difficult.
A go-around is normal when alignment deteriorates
If the aircraft cannot remain stable or within limits, crews discontinue the landing and try again or use another runway. A crosswind landing is never something that must be forced.
The aircraft must track the runway despite sideways wind
Pilots correct for drift during approach so the aircraft remains aligned with the runway centerline rather than being blown downwind.
Crab and sideslip techniques solve different parts of the problem
A crab points the nose into the wind while maintaining the desired ground track. Near touchdown, pilots may remove the crab and use rudder and bank to align the wheels.
Aircraft have demonstrated crosswind capabilities
Manufacturers publish or demonstrate limits and guidance, while operators may impose their own lower thresholds based on runway, weather or crew experience.
Gusts make control more demanding
Changing wind direction and speed require continuous corrections. A stable approach can become unacceptable quickly if gusts increase.
Runway condition changes the margin
A wet, snowy or icy runway provides less tire friction, so crosswind limits may be reduced because directional control after touchdown is more difficult.
Going around is a normal option
If alignment, speed or touchdown point is not satisfactory, abandoning the landing and trying again is a standard safety decision rather than a failure.
