Definition
A group of individual electrical wires routed together along a common path and secured with ties, lacing, or clamps so they can be installed, supported, and protected as a single unit within an aircraft.
Plain English
A set of wires running side by side, tied together so they travel through the airframe as one neat group instead of loose strands.
Context Anchor
Seen during aircraft maintenance and inspection, especially behind instrument panels, inside the body of the airplane, in wings, and near engines.
Why Pilots Care
Protects critical electrical systems from chafing, shorts, and interference that could affect instruments or controls.
Intuition Check
A wire bundle is not just a loose handful of wires. In aircraft use, it means wires grouped and secured so they can be routed, protected, and inspected as a unit.
Example Sentence 1
The technician inspected the wire bundle running along the fuselage for signs of chafing where it passed through the bulkhead.
Example Sentence 2
Secure clamps keep the wire bundle clear of moving flight control cables.
