What wind condition is the maximum crosswind landing speed of 30 kts associated with for the CRJ 700?

The maximum crosswind landing speed of 30 knots for the CRJ 700 is associated specifically with a dry runway condition. This limitation is grounded in the aircraft's performance characteristics, which indicate that under dry conditions, the landing gear and braking systems can efficiently handle crosswinds up to that specified speed without compromising safety or control during landing.

When a runway is dry, the friction between the aircraft’s tires and the runway surface is highest, allowing for better traction, controllability, and stability during the landing phase. This allows pilots to safely land in higher crosswind conditions. In contrast, wet runway conditions can reduce friction and grip, requiring lower maximum crosswind landing speeds to maintain safe control. Similarly, Condition Code 3 generally refers to a wet runway, which does not support the same crosswind limits as dry conditions. Thus, while crosswind limitations may be reduced in adverse conditions, the 30-knot limitation specifically correlates to a dry runway surface, reflecting the aircraft's performance capabilities under optimal landing conditions.
