Approach
Speeds
If the reported landing conditions contain a wind component, the final approach speed should be increased above normal VRef. The recommended final approach speed with flaps 45° is calculated as follows:
VRef plus ½ steady-state crosswind component plus all the gust component, regardless of direction.
The maximum correction is +20 kts.
The normal circling configuration is gear down, flaps 30°, and maintain maneuvering speed as per General (or VRef plus 17 kts, if greater).

Operations in Icing Conditions
Icing conditions exist at a Total Air Temperature (TAT) of 10 °C (50 °F) or below with visible moisture in any form (such as clouds, rain, snow, sleet, or ice crystals), except when Static Air Temperature (SAT) is −40 °C (−40 °F) or below.
See Operations in Icing Conditions Supplement
EDTO & ETOPS
Extended Diversion Time Operations (EDTO) and Extended-range Twin-engine Operational Performance Standards (ETOPS).
Special Approaches
Approaches between 3.5° and 4.49° require special performance considerations (“Supplement 11” in the official Airplane Flight Manual), and approaches between 4.5° and 5.5° are true “steep” approaches and have significant performance and operational differences (“Supplement 12” in the official Airplane Flight Manual).
See Special Approach Supplement
Landing Performance Assessment Using Runway Condition Code
The International Civil Aviation Organization (ICAO) Global Reporting Format (GRF) sought to replace runway contamination and depth information with a Runway Condition Code (RWYCC) that describes expected braking action without pilots needing to interpret contaminant information.
