UA Operator and Activity Permits

Now that you have registered your unmanned aircraft (UA), ensure that you have applied for the relevant permits, if applicable, before you fly your UA:

Types of Permit

Operator Permit

An Operator Permit is granted by CAAS to an organisation or individual if the applicant has demonstrated that he/she is able to operate the Unmanned Aircraft (UA) safely. The assessment will include, but limited to, the applicant’s organisational set-up, procedures to manage safety including the conduct of safety risk assessments, airworthiness of each of UA, and competency of the personnel involved in the flying of the UA. The permit is valid for up to one year.

Activity Permit

An Activity Permit is granted by CAAS to an organisation or individual for a single activity or a block of repeated activities to be carried out by a UA taking into account the location(s) of operation, type(s) of operation to be conducted, date(s) / time(s) during which the operation(s) to be conducted, operating altitude and mitigation measures to address location-specific circumstances.

There are two types of activity permits:

  • A Class 1 Activity Permit is required for UA activities conducted outdoors for purposes that are not recreational or educational in nature; or if the UA to be used for recreational purposes is over 25 kilograms in total mass; or if the UA to be used for educational purposes is over 7 kilograms in total mass. A Class 1 Activity Permit is not valid without a UA Operator Permit.
  • A Class 2 Activity Permit is required for UA activities conducted outdoors if the UA to be used for recreational purposes is 25 kilograms or below in total mass; or if UA to be used for educational purposes is 7 kilograms or below in total mass; and when the planned activity meets any of the following conditions:
    • Operating altitude higher than 200 feet (approx. 60 metres) above mean sea level (AMSL);
    • Within 5 kilometres of any civil aerodrome or military airbase; or
    • Within any restricted, danger or protected area.


Other Permits


Besides CAAS, there are other permits required from various agencies for certain aspects of the unmanned aircraft operation that come under their purview. This includes:

  • Singapore Police Force (SPF) for aerial photography and/or overflight of security-sensitive locations
  • Info-communications Media Development Authority of Singapore (IMDA) for use of radio frequencies and power limits other than in IMDA’s guidelines for short range devices.


Permit Processing Time

Please note that the average processing time of permit applications depends on the completeness of the submission of supporting documents and complexity of the UA operations:

Other permits may be issued together with the Class 1 or Class 2 Activity Permit:
