The testing with the FAA was conducted during the week of May 15-19,
2006 between the GWDI AMHS system installed at the AFL (Airport Fiji
Limited) facilities at Nadi International Airport in the Fiji Islands and
the FAA AMHS system located at the William Hughes Technical Center,
Atlantic City, New Jersey, USA. For these tests, the GWDI AMHS utilized
the Airtel ATN Router to support the connectivity to the FAA AMHS using
the X.25 protocol.

Following the successful testing with the FAA, GWDI conducted
additional testing with the Eurocontrol ECG at the their facilities in Brussels,
Belgium during the week of June 6-9, 2006. In contrast to the tests
with the FAA, the tests with the ECG were conducted using the TCP/IP
protocol and did not include an ATN Router. This was in response to the
European states decision to use the TCP/IP as the basis for communication
between AMHS systems.

The GWDI AMHS solution has been designed with a great deal of
flexibility to accommodate the use of either an X.25 based ATN router or an IP
based exchange of AMHS messages. Both protocols can be configured if
required by a system serving as a gateway between an X.25 based region
such as ASIAPAC (Asia Pacific) and the EUR-MID-NAT (Europe-Middle
East-North Atlantic) region.

GWDI acknowledges the outstanding support it received from the staff at
AFL in Fiji Islands, Naviair in Denmark, Eurocontrol in Belgium and the
FAA Technical Center in the United States.
