APPENDIX “B”
CROSS WIND LIMITS FOR CANADIAN RUNWAY FRICTION INDEX (CRFI)
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 930119|200
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.

Pressure altimeters are calibrated to indicate true altitude under International Standard Atmosphere (ISA) conditions. Any deviation from ISA will therefore result in an erroneous reading on the altimeter.
In the case when the temperature is higher that ISA, the true altitude will be higher than the figure indicated by the altimeter; and the true altitude will be lower when the temperature is lower than ISA. The altimeter error may be significant under conditions of extremely cold temperatures.
