PRESS RELEASE FOR IMMEDIATE RELEASE	October 29, 2004
BUTLER NATIONAL CORPORATION ANNOUNCES AMERISTAR JET CHARTER, INC., HAS CHOSEN AVCON FOR ITS LEARJET 20 SERIES RVSM SOLUTION
- AVCON plans to install RVSM and TAWS on 17 of Ameristar's Learjet 20 Series airplanes -
[Olathe, Kansas October 29, 2004] - Butler National Corporation (OTC Bulletin Board "BUKS") announces AVCON Industries, a wholly-owned subsidiary of Butler National Corporation, received an order from Ameristar Jet Charter, Inc., to install the AVCON/BIZJET Reduced Vertical Separation Minimums (RVSM) and the L-3 Communication Terrain Awareness Warning System (TAWS) solutions on 17 of its Learjet 20 Series airplanes. The Ameristar order includes RVSM and TAWS installations on two Falcon 20 airplanes. The AVCON/BIZJET Team has upgraded more than 60 airplanes with the AVCON/BIZJET RVSM Group Solution. The AVCON/BIZJET Team has approximately 80 orders booked or pending. Clark Stewart, President and CEO, said, "We are pleased that Ameristar has selected our RVSM solution for their Learjets. They thoroughly evaluated the available alternatives and determined that the AVCON/BIZJET solution was the best fit for their airplanes. This order adds to our RVSM momentum in the Learjet 20 Series market." Domestic RVSM goes into effect on January 20, 2005, and will allow airplanes to operate with reduced vertical spacing at altitudes of 29,000 feet through 41,000 feet. The current retail price for the installed RVSM solution at AVCON is $159,500, plus the cost of required autopilot component inspections and repairs. The AVCON/BIZJET RVSM turnkey solution requires approximately two to three weeks downtime for structural and electrical modifications to replace the existing pitot and static system, and to install the FAA approved RVSM equipment. There are approximately 500 Learjet 20 series airplanes in use worldwide. The AVCON/BIZJET Team expects many of these Learjet operators to select AVCON/BIZJET as their RVSM solution.
