Introduction

Aircrew and passengers are exposed to atmospheric radiation (neutrons and protons) during flight, which also affects avionics Prepared and induced single particle effect (SEE). In the past few years, domestic and international air crews affected the crew and passengers A great deal of research has been carried out and great achievements have been made. The standardization of atmospheric neutron radiation effects for avionics has been it has received great attention from the aviation manufacturing industry and is a further extension of ongoing work related to atmospheric radiation by aircraft crews and passengers.

Atmospheric radiation effect is one of the influencing factors of the avionics soft and hard failure rate. From the system security point of view, in use when calculating the failure rate, the method described in the ARP4754A (Common Method for Calculating Hard Failure Rates and Soft Failure Rates) also applies to atmospheric radiation Shot failure rate.

In addition, the standard reference JEDEC (Joint Electron Device Engineering Council) standard JESD89A, the standard is Electronic equipment suffers from ground-level (below 3040m) atmospheric emissions that produce soft errors in the reference standard.

This standard determines the potential impact of the aircraft on its electronic products exposed to atmospheric ionizing radiation and the disposal of these effects the general method of sound, adapted to avionics system designers, electronic equipment or components of the development and production and application of units can also refer to use.

1 Scope

This standard mainly for 18.3km flight aircraft in the airborne electronic equipment to provide protection against atmospheric radiation design guidance, but also it provides a reference for the design of atmospheric radiation effect protection of avionics in aircraft flying above 18.3km.

This standard defines the radiation environment and its radiation in the avionics environment effects, proposed in the avionics system defense Control the design requirements of these effects.

This standard is intended to guide the development of avionics equipment manufacturers and designers in the avionics single-particle effect to form a standard design Process and method.

This standard provides a detailed radiation environment to identify the avionics radiation problems required to provide electronic devices single-particle effect rate Quantitative calculation method. A comprehensive system safety analysis approach should consider the single-particle effect rate and consider both device-level and system-level proofs After the particle effect rate avionics meet the application requirements.
