Airframe Electrical Supply color?

Airframe Electrical Supply color?

• A. Green cables
• B. Blue cables
• C. Yellow cables
• D. White cables

Answer: (D)

Color coding of aircraft wiring helps technicians quickly identify what each wire feeds and avoid connecting the wrong circuits. In the UH-60S airframe electrical system, white cables mark the airframe electrical supply path, distinguishing it from other power sources and buses. This clear cue makes it easier to trace power to the airframe components, aids in safe servicing and troubleshooting, and reduces the chance of energizing the wrong circuit. Other colors are used for other systems, but white specifically identifies the airframe electrical supply.
