Why can a small drone shut down an airport?

A drone near a runway or approach path poses a collision risk to aircraft, which are most vulnerable at low altitude and high speed. Because the consequences of a strike are severe, authorities often suspend operations as a precaution until the airspace is confirmed clear.

Are all drone threats deliberate?

No. Many incursions are careless or reckless rather than hostile, but they can still cause serious disruption and danger. The threat also includes deliberate use of drones for surveillance, smuggling or attack, so security programmes address the full range.

Threats

Unmanned Aircraft (UAS / Drone) Threat

Also known as: Drone threat · UAS incursion · Unmanned aircraft system threat

The UAS or drone threat is the risk that unmanned aircraft pose to civil aviation, ranging from unintentional incursions into airport airspace that disrupt operations, to deliberate use of drones for surveillance, smuggling, or as weapons. Even small drones can force runway closures and present a collision hazard to crewed aircraft.

Unmanned aircraft systems span a wide spectrum, from consumer quadcopters to larger fixed-wing platforms. The threat they present to civil aviation is correspondingly broad. At the lower end, careless or reckless operation near an airport can trigger precautionary runway or airspace closures, with significant disruption, and creates a genuine collision risk to aircraft on approach or departure. At the higher end, drones can be used deliberately for hostile surveillance of secure areas, for smuggling across a perimeter, or as a delivery mechanism for an attack.

Because drones are small, cheap, increasingly capable and operated from a distance, they challenge the perimeter-centric model of airport security. They can approach from any direction, fly over fences and standoff distances, and may not be detected by systems designed for crewed aircraft. Authorities have responded with operating regulations, geo-fencing, registration requirements and dedicated detection and mitigation capabilities, but the pace of technology change keeps the threat evolving.

Drone activity around airports and sensitive sites is a security signal that bears on specific airports and approach corridors. As part of an aviation security intelligence picture, AeroVigil can relate reporting on drone incidents and hostile UAS activity to the facilities and operations they affect.
