If the weather at the airfield is forecast to be 600-1 for ETA +/- 1 hour, what should you do?

When the weather at the destination airfield is forecasted to be 600 feet above ground level and visibility of 1 mile within one hour of your estimated time of arrival (ETA), this indicates that weather conditions are close to the minimums for visual flight rules (VFR) operations. The criteria for flying VFR generally require better visibility and ceiling, so it becomes critical to have contingency plans in place.

Designating an alternate airfield is the correct course of action because it ensures that you have a safe option in case the weather deteriorates further or does not improve as you approach. The rules governing IFR (Instrument Flight Rules) operations also mandate that, under certain weather conditions, a pilot must have an alternate destination in mind if the forecast indicates marginal weather that could impact landing.

Thus, by designating an alternate, you maintain safety and flexibility in your flight planning, which is essential for effective risk management in aviation operations, especially when dealing with uncertain weather conditions.
