Proposed amendments to Part 139 MOS to incorporate amendments to Annex 14 Volume 1 (Amendment 15) - (CD 2507AS)

Overview

We would like your feedback on proposed amendments to the Part 139 Manual of Standards (MOS). These amendments enable the implementation of changes introduced in Amendment 15 to the International Standards and Recommended Practices, Aerodromes - Aerodrome Design and Operations (Annex 14, Volume 1).

We are also proposing to update the Part 139 MOS by removing obsolete requirements and adjusting elements associated with precision approach path indicator (PAPI) height, and matters associated with the experience and competence of aerodrome personnel. These proposed changes would replace existing rules and provide some additional requirements.

These changes are part of a global program to review and update aerodrome standards and operating procedures.

Changes arising from Amendment 15:

• precision approach runway, CAT III definition
• objects or structures on runway strips

• designation characters for taxi and apron markings
• naming of taxiway location signs
• sign size and location distances, including runway exit signs
• runway guard lights
• stop bars
• no entry bars
• siting requirements for CNS facilities

Miscellaneous updates:

• PAPI height
• aerodrome personnel
• transitional provisions (remove)
