Which factors must be considered when determining the wire size for an aircraft installation?

When determining the wire size for an aircraft installation, it is crucial to consider several specific factors that ensure not only the efficiency but also the safety and reliability of the electrical system.

Mechanical strength is essential because aircraft wires need to withstand physical stress and potential abrasion during operation, especially in the dynamic environment of flight. The ease of installation is also significant since a well-placed wire can facilitate maintenance and reduce the likelihood of installation errors. Current carrying capability is perhaps the most critical factor: wires must be sized adequately to handle the electrical load without overheating, which could lead to insulation failure or even fire hazards. Finally, the type of load, whether it is continuous or intermittent, influences how the wire will perform under different operating conditions and thus affects the overall sizing and selection processes.

Considering these factors provides a comprehensive approach to selecting an appropriate wire size that adheres to safety standards and optimizes the performance of the aircraft's electrical systems.
