Final answer:
If the weather minimums for NVG are not met, it is safest to abort the flight.
Step-by-step explanation:
In this case, the weather minimums for NVG (Night Vision Goggles) are specified as 800 and 3. These numbers refer to the visibility and cloud ceiling requirements, respectively.
If the weather conditions are below the minimums, it is generally not safe to continue with the flight. Therefore, option 2) Abort the flight due to weather is the most appropriate choice.
Changing the flight route or waiting for the weather to improve may not be effective solutions if the visibility and cloud ceiling remain below the specified minimums.
