What should you do if the weather at your alternate has deteriorated after executing a missed approach?

In the scenario where the weather at your alternate airport has deteriorated after executing a missed approach, the preferred course of action is to proceed with the approach at the new destination if it remains within limits. This approach is supported by regulations and guidelines that focus on safety and compliance with visibility and instrument approach requirements.

When considering whether to proceed, it is essential to assess the current weather conditions at the intended destination. If the weather there is still within the prescribed limits for an approach and landing, it is often safer and more efficient to continue the approach rather than diverting or returning to base. This option allows for the completion of the flight as planned, assuming that all necessary operational criteria, such as ceilings and visibility, are satisfiable.

In the context of operations, diverting or returning poses risks, especially if you are unfamiliar with alternate airports' facilities, which can introduce additional variables into the flight operation. Continuing to the new destination is a pragmatic response while maintaining compliance with instrument flight rules (IFR) and ensuring that safety remains the top priority.
