Aerodrome safety

CAAS conducts regular surveillance audits and inspections at aerodromes to verify that operations, infrastructure, and facilities comply with applicable safety regulatory requirements.


Safety regulatory requirements

These requirements can be found at:

  1. Air Navigation (139 — Aerodromes) Regulations 2023

  2. Aviation Specifications 5 - Aerodromes

  3. Aviation Specifications 6 - Heliports

  4. Manual of Standards - Aerodrome Rescue and Fire Fighting Training 2025


Advisory circulars on aviation safety

CAAS also publishes Advisory Circulars (AC) to provide practical guidance or clarity on the statutory requirements for aviation safety.

The ACs contain information about standards, practices and procedures that are acceptable to CAAS. 

The ACs may also be used to demonstrate compliance with statutory requirements in ANR-139 and the Aviation Specifications.
