Telephonics (Hall 4 Stand C12) is taking hi-fi techniques to the skies in a bid to improve communications between crew members and the ground.

Its Secure Digital Intercommunication System (SDI) is a next-generation, open architecture product for both fixed and rotary wing aircraft designed to provide secure high-quality audio and data transmissions in a modular package.

Telephonics president, Joe Battaglia, says: "SDI gives pilots the tactical edge to communicate quickly and clearly providing more opportunity for crew members to focus on the mission in hand."


The UK Defence Evaluation and Research Agency (DERA) is SDI¹s first customer after it bought systems for test and evaluation purposes. In the US, the launch of SDI has coincided with the Department of Defence needs for fully-digitised systems _to interface with newer _glass cockpit designs and enhanced digital battlefield requirements.

"SDI is a brand new product," says Stephen Esposito, Telephonics vice president Business Development. "It has been difficult for customers to afford digital systems until now ¡ this is offered at half the cost of other solutions."
