The standard references a family of wire specifications (e.g., MIL-W-22759, MIL-W-81381). Key criteria include:
: It mandates ergonomic spacing for connectors—typically requiring 1.0 inch of clearance around coupling rings, or a minimum of 0.75 inches in congested areas—to allow for manual mating and de-mating.
While the SAE AS50881 standard provides a comprehensive framework for the design, testing, and procurement of wire and cable, there are several challenges and limitations to its implementation, including:
Originally derived from the military specification , SAE AS50881 has evolved into a global benchmark for both civil and military aviation. It covers everything from wire selection and sizing to harness fabrication and installation practices, ensuring that electrical systems can withstand the rigors of flight, including vibration, temperature extremes, and pressure changes. Key Pillars of SAE AS50881
The standard mandates that wires must have enough slack to allow connector replacement without splicing. Many designs ignore this, leading to "hard wired" connectors.
