What can be a consequence of poor wire insulation in an aircraft?

Poor wire insulation in an aircraft can lead to increased risk of electrical shock and short circuits. Insulation serves as a protective barrier that prevents electrical current from leaking out of the wires and causing unintentional contact with other conductive materials. When insulation is compromised—due to wear, damage, or degradation—it can expose the conductive materials within the wires, creating dangerous conditions.

This can result in electrical shocks to personnel working on or near the aircraft, posing a significant safety hazard. Furthermore, the exposure of bare wires can lead to short circuits, which occur when electric current flows along an unintended path. Short circuits can trigger electrical fires, damage critical aircraft systems, and create potentially catastrophic situations in flight, making effective wire insulation essential for safe aircraft operation.

The other options do not correctly represent the risks associated with poor insulation. Improved electrical conductivity, for example, is not relevant since compromised insulation typically leads to unintended electrical failures rather than enhancements. Enhanced performance of electronic components and the idea of no significant issues are also misleading, as compromised insulation can severely impact aircraft safety and system reliability.
