PURPOSE AND SCOPE

This manual was developed to provide guidance material to support the Standards and Recommended Practices of Annex 6 — Operation of Aircraft, Part I, Chapter 5, Aeroplane Performance Operating Limitations, and the complimentary Standards of Annex 8 — Airworthiness of Aircraft, Part IIIB, as applicable to large transport type aeroplanes. It also presents the guidance material previously contained in Annex 6, Attachment B, which was removed from Annex 6 as of Amendment 40C, applicable 2020. This manual therefore serves as the new location for that guidance.

This manual contains guidance material following the introduction of a global reporting format for assessing and reporting runway surface conditions (applicability 5 November 2020). The global reporting format defines the information regarding runway surface condition that is communicated to flight crew, as it is directly relevant to aeroplane performance. Manufacturers should provide performance information that can be used by the flight crew in their assessment of take-off and landing performance, in particular on winter-contaminated runways. This manual presents the parameters to be used by manufacturers in developing their performance models in order to make available information that fulfils the intent. However, performance data and a limited number of contaminant types or braking action categories covered in the global reporting format will never reflect the complexity of the situations that can develop in active winter events. This manual includes information that flight crew should be made aware of when assessing performance and explains how to use the available data to build their awareness of the situation and its potential development.

This manual introduces the global reporting format for runway conditions, as it may impact take-off and landing performance. The content is then organized by flight phases; each phase has a separate chapter. Appendices A and B contain examples for the continued operation of piston-engine aeroplanes with two, three or four engines which cannot comply with the level of performance intended by the provisions of Annex 6, Chapter 5. These examples have been reproduced in their original composition in two separate appendices, having previously formed a large part of the content of Attachment B in Annex 6.
