STANAG 4626

from Wikipedia, the free encyclopedia

STANAG 4626 or EN 4660 is the name of a standardizationagreement ofthe NATO signatory states, which began in the early 1990s.

The aim of this agreement is to develop a modern avionics architecture that will be used in the development of new aircraft and in programs to upgrade existing aircraft. What is essential for STANAG 4626 is the strict separation of a function in hardware and software , i.e. in the application and the resources it uses. At the beginning of development, this represented a completely new approach in avionics . Up until now, software can only be certified in combination with hardware. The industry expects high cost savings in future systems from the separation in development and possibly also in certification. In this context one speaks of incremental certification .

STANAG 4626 is managed by the UK Department of Defense. Many major European airlines are involved in the development. These include a .:

The ASAAC (Allied Standard Avionics Architecture Council) working group was founded to develop the STANAG. For this reason, the ASAAC standard is often used, as there was no other name during development. The working title of the official EN standard - Modular and Open Avionics Architectures (MOAA) - is still largely unknown. ASAAC's contractual partners include:

The ASAAC program was divided into two phases:

  • In the first phase, a basic concept was developed which is based on the IMA concept , which was also flaring up at the time .
  • In the second phase, a draft standard was developed. Development ended in May 2004.

Since then, the standard has been accompanied by a series of test setups (demonstrations). In 2007, an open source version of an operating system stack for STANAG 4626 was published, which is based on POSIX .

Above all, Germany tried to ratify the second draft. Stanag 426 has been a European standard since March 2010 . The text of the STANAG 4626 was published under the EN 4660 Aerospace series - Modular and Open Avionics Architectures . In Germany, the standard is valid as DIN standard DIN EN 4660 with parts 001 to 005:

  • DIN EN 4660-001: Aerospace - Modular and open avionic architectures - Part 001: Architecture
  • DIN EN 4660-002: Aerospace series - Modular and open avionics architectures - Part 002: CFM (common functional modules)
  • DIN EN 4660-003: Aerospace - Modular and open avionic architectures - Part 003: Communication / network
  • DIN EN 4660-004: Aerospace - Modular and open avionics architectures - Part 004: Packaging
  • DIN EN 4660-005: Aerospace series - Modular and open avionic architectures - Part 005: Software
