What is a primary consideration when crimping terminals onto wires for aircraft use?

When crimping terminals onto wires for aircraft use, the mechanical strength of the connection is a primary consideration because it directly affects the reliability and safety of the electrical system. In aviation environments, connections must withstand various stresses, including vibration, temperature fluctuations, and potential corrosion due to environmental factors. A strong mechanical connection ensures that the terminal remains securely attached to the wire, preventing failures that could lead to electrical malfunctions or hazardous situations.

The mechanical integrity of crimped connections is crucial because weak or improper crimpings can create resistance points, leading to overheating, intermittent connections, or complete electrical failure. Therefore, achieving a robust crimp that meets the specific strength requirements for aircraft applications is essential for maintaining the overall functionality and safety of the aircraft's electrical system.
