How far must an aircraft be from any spark hazard while refueling?

The correct distance that an aircraft must maintain from any spark hazard while refueling is 15 meters. This requirement is based on safety protocols designed to minimize the risk of ignition during the refueling process. The presence of spark hazards, such as electrical equipment or static discharge sources, can potentially ignite flammable vapors released during refueling. By establishing a 15-meter separation, it ensures that any possible ignition sources are far enough away to significantly reduce the risk of fire or explosion.

Regulatory guidelines and safety programs emphasize the importance of this distance in maintaining a safe fueling environment, thereby protecting both the aircraft and ground personnel from potential hazards. Ensuring compliance with this safety standard is critical for operational safety in aviation.
