Please refer to the accompanying schedules highlighting our Statement of

A Company spokesman commented: "The demand for our Air Data equipment has
materialized as anticipated and is expected to continue beyond the FAA's RVSM
compliance date of January 20, 2005. Continued demand for the replacement of
obsolete and troublesome equipment will augment installations on aircraft that
missed the FAA compliance date."

At June 30, 2004 the Company's backlog of released business reached a
quarter-end record $27.9 million. This reflects a 22% increase from the June 30,
2003 backlog of $22.8 million. In addition the Company has an additional $17
million in follow-on options for release in subsequent periods that has not yet
been recognized in firm backlog.

Along with our sales increase, the Company increased its investment in
Engineering & Product Development by over 100% in the current quarter and by 59%
for the year-to-date period. This investment was substantially linked to the
issuance of the Cockpit/IP(TM) TSO certification received on July 2nd from the
FAA. Further, this investment assures that new Flat Panel and Air Data Systems
will come to market at the end of calendar 2004.


The company will host a conference call tomorrow morning, July 29, 2004 at 10:00
am local time to discuss these results. Please call in to participate at (888)
792-8459. Also, our web site (www.innovative-ss.com) will carry the conference
call live and have it available for subsequent listening for a period of 30
days.
