Application for Aerial Activities
Some aerial activities can potentially pose a hazard to air navigation, either due to the close proximity between an object in the air and an overflying aircraft, or an object may cause an obstruction along the flight path. As such, prior clearance needs to be sought from CAAS before interested parties carry out such activities.
