What should you do if you lose sight of the ramp marshal during operations?

When you lose sight of the ramp marshal during operations, conducting a roll call report is the appropriate action to take. This procedure ensures that you account for all personnel involved in the operation and assess the current situation effectively. A roll call allows you to gather information about the marshal's last known position and confirm the safety of everyone involved before proceeding. It prioritizes communication and coordination in the critical environment of ramp operations.

Continuing operations without confirming the marshal's status can lead to confusion and safety risks, which is why options that suggest signaling or increasing speed could potentially create further hazards. Aborting the operation immediately might be necessary in some situations, but first ensuring that all personnel are accounted for is crucial in maintaining operational integrity and safety in the ramp environment.
