What is the maximum fuel limit below which a straight-through initial is expected in single runway operations?

The maximum fuel limit below which a straight-through initial is expected in single runway operations is identified as 350 lbs. This limit is established based on the operational protocols designed to ensure safety and efficiency during landings and takeoffs at airports with single runway configurations.

In single runway operations, managing fuel levels is critical to avoid unnecessary go-arounds and to ensure that aircraft can safely land without exceeding maximum weight limits. The threshold of 350 lbs signifies a balance where the aircraft can execute a straight-through approach while maintaining operational parameters. Below this limit, the flight crew can anticipate that their landing gear and approach can be managed effectively, allowing for a straightforward landing without the need for additional maneuvers.

Such established thresholds help in maintaining smooth operations, optimizing runway usage, and minimizing delays, particularly in busy air traffic environments.
