The main peculiarity of practical implementation of A-type technology was that realized systems allowed to verify theory and methodology of information processing in various conditions.

The tests of A-technology were conducted on some airborne systems: autonomous astronavigational system (AAS) and fuel gauge and control systems for jet planes.

Some results were received and investigated using software simulator of CAD system designed on the basis of A-type technology. The following problems have been verified:

representability of data in various formats in computer; realization of elementary computing processes; ranges of use and validity of various data models. The special attention has been given to data confidence and reliability determination, of both, primary and processed, and to verification of adequacy of the models and objects.

Distinctive feature displayed by all constructions was rather higher efficiency in analysis and synthesis of instrumental complexes as compared with the traditional CAD systems.

For AAS use of A-type technology resulted in decreasing ROM size for operating program and the frame period in more than ten times.

For fuel gauge and control systems the measurement error decreased from 2,5 per cent to 0, 5 per cent of full tank, due to restructuring of data processing methods of primary information from gauges.
