What you need to be a Singapore Air Operator

If Singapore is your principal place of business and you intend to operate your aircraft for the purpose of public transport, you are required by the Air Navigation Regulations (ANR) of Singapore to hold an Air Operator Certificate (AOC) before the anticipated start of operations. A commercial air permit - i.e. regulatory approval from CAAS as required by the Air Navigation (Licensing of Air Services) Regulations (see Air Services for Hire or Reward tab below) must also be obtained prior to commencing scheduled or non-scheduled air services within Singapore.

The Air Navigation Regulations Part 91, 119, 121, 135 and 98 state the conditions, qualities, qualifications, standards and procedures necessary to qualify for and maintain an AOC, as well as incorporate new practices or procedures to ensure the safety of the travelling public.

For more information, please contact CAAS' Air Transport Division (see Contact Details tab below).
