If a small leak develops around the tank valve stem, what action is appropriate if no other tanks have sufficient fuel for landing?

Turning the leaking tank handle to the full-open position is an appropriate response in the event of a small leak around the tank valve stem when no other fuel tanks are available for landing. This action ensures that the fuel is flowing properly and reduces the potential for pressure buildup that can occur if the valve is partially open, which might be exacerbated by a leak. A fully open valve allows for a consistent flow of fuel, which can potentially maintain pressure and performance in the burner system, thereby aiding in keeping the lighter-than-air craft operational for the landing.

In situations where a leak is present, it is critical to maintain control over the fuel delivery to avoid an unpredictable fuel supply, which could lead to potential hazards. Managing the valve effectively helps in mitigating risks associated with leaks by promoting stable operation.

Using tape to seal a leak is generally not advisable in such situations due to its temporary nature and the possibility that it may not fully contain the fuel or pressure. Reducing the burner flame likewise does not address the underlying leak issue and could lead to insufficient lift if the fuel supply is compromised. Monitoring pressure is important, but it does not take immediate action to stabilize the situation; instead, it focuses on observation without a proactive approach to managing the fuel flow.
