If a discrepancy is noted prior to takeoff, what must you do?

When a discrepancy is noted prior to takeoff, the correct course of action is to contact dispatch immediately. This is crucial because any discrepancies could potentially impact the safety and operational integrity of the flight. Dispatch has the responsibility to coordinate and assess the situation, providing guidance on whether the flight should be delayed or if corrective actions need to be taken before departure.

By notifying dispatch right away, you ensure that any necessary adjustments can be made based on the severity of the discrepancy, which can include sending maintenance personnel to address the issue or deciding to defer certain operations until it's resolved. This proactive approach is vital in maintaining safety standards and regulatory compliance in aviation operations, as addressing potential issues before takeoff is paramount to ensuring a safe flight.
