Exhibit A

Tel-Instrument Electronics Corp Announces Preliminary Results for 2006

    CARLSTADT, N.J.--(BUSINESS WIRE)--April 6, 2006--Tel-Instrument
Electronics (Tel) announced today that its preliminary estimates for
results of operations for the fourth quarter ended March 31, 2006
indicate a substantial loss. Fourth quarter expenses include
approximately $300,000 in accounting and restructuring charges
associated with its ITI subsidiary. Additionally, sales in the fourth
quarter were below Company targets and quarterly amounts reported for
the first three quarters of the current fiscal year. Research and
Development costs remained high due to the cost of finalizing the
design for the new AN/USM-708 (CRAFT) next generation multi-function
test set for the U.S. Navy. For the 2006 fiscal year ending March 31,
2006, Tel anticipates reporting a consolidated year-end operating loss
as profits from its avionics business were more than offset by losses
and charges at ITI. The Company will issue its audited results of
operations for fiscal year 2006 when they are finalized.
    Tel is in a transitional phase between the end of deliveries in
fiscal year 2006, pursuant to its multi-year AN/APM-480 contract, and
the commencement of production deliveries under its previously
announced multi-year AN/USM-708 contract. The Navy technical
evaluation process for AN/USM-708 is scheduled to begin in April 2007
and product deliveries are currently expected to begin at the start of
the 2008 calendar year. With respect to existing business, commercial
sales remain depressed and several medium-sized military orders have
been delayed. Absent success on several large pending contracts, Tel's
annual sales are expected to remain below recent levels for at least
the first two quarters of the 2007 fiscal year. R&D outlays are
expected to remain high through the first three quarters of the
current calendar year.
    In recognition of the challenging business outlook, on March 31st
the Company adopted a profit improvement plan for Tel and ITI which
management believes will reduce costs substantially. This includes
selected layoffs, a reduction in operating expenses, modifications to
employee benefits, and further integration of ITI's operations into
Tel. While the near-term competitive and economic situation remains
difficult for both the avionics and hydrographic markets, management
remains optimistic about the Company's prospects. Tel has upgraded its
management team and engineering staff over the last several years and
the new digital technology incorporated into the AN/USM-708 could have
applications outside of Tel's traditional avionics business.
    In March 2006, two officers converted interest bearing convertible
notes from the Company into 27,500 shares of common stock. In the 2006
fiscal year, employees and board members exercised stock options and
were issued 84,000 shares of common stock. Although the Company has a
current Registration Statement on Form S-8, allowing employees to sell
stock received upon exercise of options, to the best knowledge of the
Company, no shares were sold by current employees.
    At March 31, 2006, the Company had available cash of about $1.8
million, an unused Bank line of credit of $1.75, million and positive
working capital of approximately $4 million.
