Abbreviated Test Language for All Systems
Abbreviated Test Language for All Systems (ATLAS) is a MILSPEC language for automatic testing of
avionicsequipment. It is a high-level computer languageand can be used on any computer whose supporting softwarecan translateit into the appropriate low-level instructions.
The ATLAS language was initially developed by an international committee made up of representatives from the airline industries, military services,
avionicsmanufacturers, and Automatic Test Equipmentmanufacturers. The goal of the committee was to design a standard English-like language that could be easily understood and used by both avionics and test equipment engineers. The result was the ATLAS language specification, published by Aeronautical Radio, Inc.
The ATLAS language is oriented toward the
Unit Under Testand is independent of the test equipmentused. This allows interchangeabilityof test proceduresdeveloped by different organizations, and thus reduces costly duplication of test programmingeffort.
The first ATLAS specification developed by the international committee was published in 1968. The basic document has been revised several times.
The ATLAS programming language incorporates an online compiler (
OLC), Test executive ( TEXor Test Exec), and file managerand media exchange ( FMX) packages. Test executive is the mode ATLAS is run in on test stations while testing electronic equipment.
A standard ATLAS program structure consists of two elements: preamble structure and procedural structure. The ATLAS programming language makes extensive use of variables and statement syntax. An ATLAS statement consists of a flag field, statement number field (STATNO), verb field, field separator, variable field, and statement terminator. Each and every ATLAS statement is terminated with the currency symbol ($).
ATLAS is used in the Air Force primarily on test stations for testing the avionic components of the
F-15 Eagle, F-16 Fighting Falcon, C-5 Galaxy, C-17 Globemaster III, and B-1 Lancer. The U. S. Navy uses or has used ATLAS-based programs for testing avionics systems of the SH-60 Seahawk, E-2C Hawkeye, F-14 Tomcat, F/A-18 Hornet, S-3 Viking, A-6 Intruderand EA-6B Prowler.
ATLAS statement structure
A standard ATLAS statement:
F STATNO | | VERB |, | VARIABLE FIELD | | $
Sample ATLAS Statements:
000250 DECLARE,DECIMAL,'A1'(4)$ 000300 FILL, 'A1', 'NUM', (1) 1, 5, (2) 20, 87, (3) 15, 12, (4) 30, 18$ C AN ATLAS COMMENT HAS A 'C' IN COLUMN 1 AND ENDS WITH A DOLLAR SIGN $
