Avidyne Corporation, a leading provider of integrated flight deck and safety systems for general aviation aircraft, announced today that they have partnered with Advanced Data Research Florida, Inc. (ADR Florida) to deliver worldwide datalink graphical weather and text messaging using Avidyne's MLX770/MLX780 Iridium-based datalink transceivers and ADR's Electronic Flight Bag (EFB) products.

The addition of an EFB interface extends the Avidyne MLX Series' display compatibility, providing another display option for Part 23 and Part 25 aircraft operators in Europe and around the world who want access to the safety-enhancing benefits of satellite datalink weather. These aircraft may now utilize value-priced EFBs running Avidyne's FlightMax Multi-function Display (MFD) software with an Avidyne MLX Series transceiver to achieve the same levels of in-flight awareness and two-way communications capability as other Avidyne-equipped customers.

"We are very pleased to partner with Avidyne to make datalink weather available for our EFB customers around the world," said Michael Schmidt, Vice President of Aviation Sales of ADR Florida. "Avidyne's proven datalink experience, recognized MFD interface, and the fact that they operate their own Network Operation Center (NOC) uniquely position them as the premier provider of worldwide datalink weather."

"ADR is a great launch partner for Avidyne as we continue to grow our MLX product reach into the Part 25 market," said Patrick Herguth, Avidyne's Chief Operating Officer. "We worked closely with the ADR engineers to port our existing MFD software into their EFBs, which reduced time to market and provided a full-featured and industry-standard user interface that pilots will really appreciate for accessing worldwide datalink weather."

"Adding EFB support for our MLX series of datalink transceivers is in line with our strategy to make our safety-enhancing products available to a wider market," said Avidyne president Dan Schwinn. "Avidyne is all about making avionics that are simpler and easier to use, which equates to making flying safer, and this partnership brings our easy-to-use MFD pilot interface and our industry-leading safety sensor technology to business-class aircraft operators around the world."
