Airport security experts in Aberdeen have stepped up measures to stop the threat of drones grounding flights.
It comes after departures at Heathrow were suspended for around an hour on Tuesday after a drone was spotted near the runway.
Three weeks ago drone sightings caused chaos at Gatwick Airport hitting the travel plans of 140,000 passengers just before Christmas.
An Aberdeen International Airport spokeswoman said: “While we cannot discuss specific security measures, we are very much alert to the threat posed by drones, particularly following the reported sightings at Gatwick and Heathrow airports.
“We are continuing to work closely with the UK Government, the Civil Aviation Authority and Police Scotland to ensure our processes are both appropriate and in line with current threat assessments.
“We remain vigilant as always and would remind people that the use of drones within close proximity to an airport is both extremely dangerous and a criminal offence.”
