DOD-STD-1788 Trays

DOD-STD-1788A: DOD-STD-1788 series trays were developed to define the tray-requirements for the form factor, design and environmental tolerance of Avionic equipment installed in military aircraft. Modeled after ARINC 600, DOD-STD-1788 trays are intended by design to reduce acquisition costs when identical avionics functions, packaged in different configurations designed for specific type aircraft, are greatly reduced or eliminated entirely. The standard limits a given tray’s ATR size to ¼ - 1½ ATR.
