Avoiding instrumentation interference and signal losses at high frequencies
As part of an aircraft’s certification for flight, aircraft must demonstrate safe operation within a range of environmental conditions. This includes Electromagnetic Environmental Effects (E3) testing which, for civil aircraft, includes High Intensity Radiated Field (HIRF) and lightning tests. HIRF and lightning testing involve:
- High level whole aircraft testing
- Hybrid of low level aircraft testing and high level equipment testing.
For both test methods, fiber optic links (FOLs) are essential to prevent…
