Wichita, KS--July 28, 2005--Aerosonic Corporation, a leading supplier of precision flight products for commercial, business and military aircraft, and Mid-Continent Instruments, a leader in General Aviation instrumentation and worldwide distribution and support, announced today that the companies have agreed to jointly produce and market a complete standby instrument suite for the General Aviation market. Mid-Continent Instruments, headquartered in Wichita, Kansas will provide their new 2" Artificial Horizon Indicator, while Aerosonic will provide their popular 2" mechanical Altimeter and Airspeed indicators. The agreement also allows for combined marketing of an upgraded package which replaces the mechanical Altimeter and Airspeed with Aerosonic's new digital instruments.

"This package is aimed at the General Aviation market, which includes light jets, turboprops and twin or single engine piston aircraft. Manufacturers in this segment of our industry need a simple and affordable solution for their standby instrument requirements," stated Todd Winter, Mid-Continent's President.

General Aviation Manufacturers Association (GAMA) recently released first quarter 2005 numbers stating that, for General Aviation, the number of new aircraft built increased to 627 aircraft, up 15.7 percent over the first quarter 2004, while industry billings for new airplanes rose to $2.7 billion.

"This agreement combines the strength of two companies, who together create increased value and safety for our customers. Orders have already been received from two manufacturers with many others showing strong interest. This unique `niche' product offering provides a new and exciting growth opportunity for both Aerosonic and Mid-Continent," said Mark Perkins, Aerosonic's Executive Vice President.
