Geoffrey S.M. Hedrick, Chairman and CEO, 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 the significant
number of installations on aircraft that missed the FAA compliance date."

The General Aviation market (business jets) currently represents the largest
demand for RVSM solutions. In this market, Innovative Solutions is a leading
supplier of Air Data equipment with certified solutions for Falcon, Cessna
Citation, Learjet, Gulfstream, Sabreliner, Raytheon King Air, Beechjet,
Westwind, Hawker and Challenger business aircraft. The Company also has
certified solutions for a wide variety of commercial air transport aircraft
including DC-8's, DC-9's, B-707's, B-727's and B-737's, and Military aircraft
including A-10's, KC-135's, RC-135's and C-130's.

At September 30, 2004 the Company's backlog of released business reached a
record $35.4 million. This reflects a 47% increase from the September 30, 2003
backlog of $24.1 million. In addition the Company has an additional $10 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 $1.4 million or 42% in the year. This
investment was substantially linked to the issuance of the Cockpit/IP(TM) TSO
certification received on July 2nd from the FAA. Further, this continued level
of investment would support new Flat Panel and Air Data System development and
follow-on product introductions in calendar 2004 and 2005.


The company will host a conference call tomorrow morning, November 18, 2004 at
10:00 am local time (EST) to discuss these results and our business outlook.
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.
