Captive balloons1 are large and can measure up to 2 to 3 metres in diameter. If released, captive balloons may drift far from the point of release, to areas and heights that may affect aircraft operations. This may in turn endanger lives and cause harm to the property – in the air and on the ground. Captive balloons should be monitored at all times.
How Do I Hoist A Captive Balloon Safely?
A captive balloon should be fitted with a mechanism that destroys the balloon should it break free of its tether.
The hoisting of a captive balloon should not be conducted within these limits without a permit:
- Within 1km of the flight funnels of an airport/airbase
- Higher than 130 feet above mean sea level outside flight funnels but within 5km of an airport/airbase
- Higher than 290 feet above mean sea level outside 5km of an airport/airbase

Important Note: All captive balloons must not exceed 3 metres in diameter regardless of the location and height at which they are operated. |
Do I Need To Notify CAAS In Order To Hoist A Captive Balloon?
Yes. If you are planning to hoist a captive balloon within the area and height limits, you will need to submit a notification to CAAS.
When Do I Need A Permit To Hoist A Captive Balloon?
A permit is required from CAAS when hoisting captive balloons outside the area and height limits. Applications will be assessed on a case-by-case basis. It will take 7 working days to process your application, as assessment will be conducted in consultation with the Republic of Singapore Air Force (RSAF).
1A captive balloon is a pilotless balloon that is tethered to the ground, or to an object on the ground.
