           Tel-Instrument's T-47N IFF Flight-Line Test Set
                   Receives Official Certification

    CARLSTADT, N.J.--(BUSINESS WIRE)--April 13, 2005--Tel-Instrument
Electronics Corp. is proud to announce recent certification of its
T-47N flight line test set for use with U.S. Department of Defense
(DoD) Mark XII "Identification Friend or Foe" (IFF) equipped aircraft.
    After a detailed evaluation, the U.S. DoD International AIMS (Air
Traffic Control Radar Beacon System, Identification Friend or Foe, MK
XIIA, System) Program Office (PO) has verified that the T-47N complies
with all DoD AIMS performance standards. The AIMS PO also examined and
approved Tel-Instrument's production facility and acceptance test
procedures.
    The DoD AIMS PO was established for the configuration control, and
oversight responsibility of the Mark XII IFF architecture, which
includes performance/ interoperability evaluation and certification of
sub-systems at both the end item (black box) and integrated platform
(aircraft) levels.
    IFF systems are the primary means of aircraft identification in
Air Defense operations. Proper use of IFF procedures facilitates rapid
engagement of enemy aircraft, conserves Air Defense assets, and
reduces risk to friendly aircraft.
    Harold K. Fletcher, the Company's Chief Executive Officer, said,
"Tel-Instrument is proud that the AIMS PO has certified our T-47N
product. An integral part of the Company's practice is to strengthen
its position in the military marketplace by obtaining official product
certifications and approvals. The T-47N is a multi- function
flight-line test set which also provides Tactical Air Navigation
(TACAN) and Traffic Collision Avoidance System (TCAS) test
capabilities, in addition to a full suite of Transponder-Interrogator
IFF test capabilities."
