Abstract

The article presents the structure of the on-board radio-electronic equipment that meets modern international requirements of CNS/ATM conception and is based on integrated modular avionics (IMA) principles. Implementation of IMA conception allows provide high reliability, enhanced functionality and compliance with modern requirements to on-board radio-electronic equipment. Architecture of the on-board equipment includes computer complex, description of information for flight deck information management field and software applications.

The computational part of the complex project includes the contents and datasheet of computing blocks, as well as the contents and designation of mezzanine modules, which perform special functions and determine functionality of the crates.

The flight deck information management field arrangement corresponds to modern allocation schemes of information consoles and allows provide their effectiveness and ergonomics. This field consists of five 15’’ multifunction displays, two head-up displays and two Electronic Flight Bag (EFB) data tablets for the pilot and co-pilot. The article presents the description of and information frames distribution over multifunction displays.

The article outlines the on-board equipment functions executed by software applications while IMA conception realization. Functional software realizes all modern communication, navigation and surveillance functions. The software applications are executed by the computation complex crates. The article suggests the applications distribution over the crates according to their functionality.

The proposed project of on-board equipment complex differs from the existing ones in large state integration of IMA systems, realizing functions of automated control systems, flight-control-navigation and radio-communication equipment. The project of on-board equipment complex for prospective transport airplane presents scalable multifunction fault-tolerant complex corresponding to the requirements for transport category aircraft, and meeting the prospective ICAO requirements to air traffic navigation and control.
