1. See Glossary at Appendix I for all abbreviations and acronyms.
2. All times are UTC, unless otherwise indicated. Paris time is UTC + 2 hours. Toronto time is UTC - 4 hours.
3. See Section 1.7.10, Red Alerts, for an explanation of red alerts.
4. See Appendix G
5. See Section 1.17.8, Air France Calculation of Landing Distance, for a definition of landing distance.

9. The airport is at the centre of the circles.
10. An aircraft approach category is based on 1.3 times its stall speed. As an example, a Category D aircraft would have a speed 141 knots or more but less than 166 knots.
11. The take-off distance available is equal to the length of the runway plus the length of clearway. Runway 24L has a clearway of 1000 feet; a clearway is defined as the rectangular area over which an aircraft may make a portion of its initial climb to a specified height.
12. Standards are mandatory for airport certification unless a deviation has been approved.
13. Zulu is another term for UTC.
14. Driver's enhanced vision systems allow for increased visibility in darkness, fog, or smoke and can provide for enhanced navigation and tracking.
