When should refueling be terminated based on turbulence levels?

Refueling should be terminated during moderate turbulence due to the increased risk it poses to safety and operational stability. In moderate turbulence, the aircraft can experience significant movements that can impact the ability to maintain proper fuel transfer and create hazardous conditions for both the refueling crew and the aircraft.

When moderate turbulence is present, the risks associated with refueling operations, such as spillage or loss of control of the fuel transfer equipment, increase notably. This can compromise not only the safety of the personnel involved but also the integrity of the aircraft systems. Therefore, the decision to terminate refueling in moderate turbulence is a precautionary measure to enhance safety.

While light turbulence may not warrant immediate cessation of refueling operations, and severe turbulence presents even greater challenges, the definitive guideline is to halt refueling during moderate turbulence to ensure that safety protocols are upheld effectively.
