A pocket-sized device that could save a pilot's life is on display at Kannad (stand 391).

The French company's XS-4 personal locator beacon can be easily activated by a pilot in difficulties anywhere in the world. It will transmit two signals simultaneously - one to the Global 406 MHz international search and rescue satellite system and the other a homing signal designed to speed up local recovery responses.

Business manager Christian Belleux says the waterproof device, which costs €255 ($335), is the "lightest and smallest" on the market. It weighs 150g (5.3oz), is 106mm (4.1in) long with a width of 47mm and operates in temperatures of between -30°C (-22°F) and 70°C.

Activation is achieved by unwrapping an antenna and pressing a button that causes an indicator ight to flash a Morse code SOS pattern. Once activated, the signals transmit continuously for 24h. Belleux says the output transmission ensures a call for help gets through to the authorities "whatever the conditions".

The highly visible yellow XS-4 GPS has a five-year warranty and users can register their device on a dedicated website.

Also on show on Kannad's stand is its 406 AF-Compact emergency locator transmitter beacon that can be fitted on to light aircraft.
