Birds and airfields go together as successfully as pilchards and custard, so British company Wingaway's display outside Hall 1 is particularly relevant if you run an airport.
Bird alarm cries are the proven way to move our feathered friends away from the intakes of jet engines. Wingaway's digital products help by reproducing anguished squawks at frighteningly high decibel levels. Originally recorded by the British Ministry of Agriculture, Fisheries and Food (MAFF), the sounds frighten birds away but only if the recordings aren't played too frequently.
Cigar lighter
Most airport systems are vehicle-mounted because the last thing you want is a random system that frightens the birds away just as an aircraft is landing or taking off. When in-vehicle, the system is powered by the cigar lighter and the range of bird alarm calls includes just about anything that could get sucked into a jet engine or collide with a propeller.
Both of London's major airports - Heathrow and Gatwick - use Wingaway's system while the export market is hotting up thanks to installations in Australia, Germany, Austria, Holland, Ireland, the Czech Republic and Hong Kong. The Greek air force is particularly interested as it has so many active airfields on small islands where seabirds are a particular problem.
And in case you're wondering, the loud-speakers don't have 'tweeters'...
