This chart provides information for calculating headwind and crosswind components and the vertical lines indicate the recommended maximum crosswind component for reported CRFI.

Example: CYOW CRFI RWY 07/25 - 4 .3 930119l200

Tower Wind 110° 20 KT.

The wind is 40° off the runway heading and produces a headwind component of 15 kt. and a crosswind component of 13 kt. The recommended minimum CRFI for a 13-kt crosswind component is .35. A takeoff or landing with a CRFI of .3 could result in uncontrollable drifting and yawing.
