Creative use of Ada in the A-10 control and display unit software

Abstract

The Global Positioning System (GPS), the improved data modem (IDM), a data transfer system (DTS), and a new control and display unit (CDU) are being added to the avionics suite of the A-10 aircraft. The CDU software has been written in Ada. The CDU software design embodies many features and extensions of Ada real-time inter-task control and communication mechanisms. The design is object-oriented and makes extensive use of generic packages.
