What can airports to do prevent drone incursions?

In recent weeks, drones have disrupted the airspace in Europe. This has caused airport closures and flight cancellations. As tensions between the West and Russia have increased over its conflict in Ukraine, finger-pointing has occurred. However, Moscow denies any involvement while investigators continue to gather evidence. Governments and regulators face pressure from the public to find solutions.

Why are Drones a growing problem at airports?

Monitoring service Enigma has detected at least 18 drones in Denmark, Sweden Norway and Germany since September 16. Many, but not all, were in close proximity to airports.

Since 2005, drone incursions in Britain have affected airports such as Gatwick and Heathrow. However, this year there has been an increase in the number of incidents. The data shows persistent activity for several weeks and possibly coordinated incursions at specific dates, said an Enigma spokesperson without providing any further details.

Airport drone spottings have been particularly disruptive. Airport closures are costly and affect the entire aviation system, causing delays across Europe.

Ourania Georgoutsakou said that the increasing number of incidents would "accelerate" the implementation of protocols in order to minimize disruptions within an "overstretched, fragmented European Airspace". Protocols include frequency checking, monitoring and jamming.

Both civilians and investigators have been trying to determine what types of drones were flying, their capabilities and who was controlling them. Chief executive of Dyami Eric Schouten, a security advisory firm, said that the chaos caused by recent incidents could be an indication of hybrid warfare tactics.

Ursula von der Leyen, President of the EU Commission, said that recent drone incidents and other violations of airspace show Europe is now facing hybrid warfare. It must respond to this with measures beyond traditional defense. She stated that Russia's goal is to "sow a division" in Europe.

What technology do airports have to fight back?

On the market are a variety of technologies, such as microwaves, lasers, and missiles. The capabilities range from drone detection to jamming frequencies used by drones and shooting down.

What is the challenge? The challenge?

The European Aviation Safety Agency will issue guidance in 2021 on how to deal with drone disruptions. Some national governments have also enacted regulations that limit drone flights.

Airports purchased counter-drone devices from companies such as Dedrone Thales and DJI Aeroscope. However, the majority of these tools only offer detection technology. Germany's federal government is proposing a law that would allow police to shoot drones down if necessary after drone sightings disrupted Munich Airport earlier this month. However, introducing lasers or missiles to shoot down drones within civilian airspace has its own set of safety concerns. These include the potential for damage to civilian aircraft as well as wider infrastructure.

You must be certain that the object is hostile. Then you can intervene. "There are many ifs and buts," explained Dutch drone expert Wiebe De Jager. He warned that most drone alarms are false alarms.

Experts say that any major action would require a clearer policy from the government. For now, airports will mainly stick with detection tools.

WHAT'S NEXT?

Experts predict that drone incursions will increase in frequency across Europe.

Airports aren't the only places where drones could cause disruption. Drones can also target prisons, seaports and nuclear facilities.

Experts said that although the disruptions highlighted the vulnerabilities, the recent incursions will bring greater clarity and action by authorities. They will also force them to coordinate countermeasures across sectors.

Stijn Willekens is the Chief Executive of Active Drone Security Solutions. "I hope that it does really shake things up," he said. (Reporting and editing by Joe Brock, Mark Heinrich, Ilona wissenbach, Toby Sterling; reporting by Joanna Plucinska).
