Eventide ARGUS 5000 - Page 177

Regulatory Issues
The Argus 5000 and 7000 are "TSOd" and "STCd," which means that they meet
specific FAA criteria for use in aircraft as a required instrument. A TSO (Technical
Standard Order) requires that the unit meet certain requirements, such as electrical and
environmental testing, and a truly remarkable amount of paperwork must be generated
to prove this. The STC (Supplementary Type Certificate) indicates that the unit in
question can be installed in the aircraft and meets FAA requirements for operation in
the aircraft during instrument flight and can be used (in the case of the Argus 5000) as
a required instrument under certain conditions. The Argus 5000 must be connected
to the aircraft's gyroscopic heading system to be eligible for IFR approval.
Database Differences
The Argus 5000 Ver. 5.x database EEPROM holds 4Megabytes of data. This is two
times the maximum capacity of the Argus 5000 with software versions through 4.x,
and can be increased if need be.
This increased capacity permits making more database features, such as airways and
intersections, standard, and eliminates the limitations on runway length previously
encountered on the international database. Because the EEPROM is electronically
eraseable, no chip changes are required for updating, and, in fact data can be loaded
from a PC. We encourage this by making databases available electronically and on
disk at a significantly reduced price.
Upgrade Path
All Argus 5000 and 7000 models, no matter how old, can be upgraded to version 5.x.
All units are upgraded by exchanging the old database board using EPROMs for a new
one using EEPROMs. In addition, it may be necessary to modify (for recent) or
exchange (for older) the CPU board.
