What hazard is associated with wing-tip venting during fueling?

• A. It may produce a hazardous condition
• B. It increases fueling speed
• C. It reduces risk of fire
• D. It eliminates spills

Answer: (A)

Wing-tip venting during fueling releases fuel vapors into the surrounding air, and those vapors can form a flammable mix near the aircraft. If an ignition source—such as static discharge, a hot surface, or electrical equipment—is present, it can ignite the vapor cloud, creating a hazardous condition. This is why grounding, bonding, and following proper fueling procedures to control vapors are essential. The other options don’t fit because venting does not speed fueling, does not inherently reduce fire risk, and does not eliminate spills.
