Is an alternate airport required when the weather is forecasted to be 2000' OVC and 3SM visibility?

The requirement for an alternate airport in aviation is determined by specific weather conditions and regulations set forth by the FAA and other aviation authorities. In this scenario, the weather is forecasted to be overcast at 2000 feet and visibility of 3 statute miles.

When planning a flight, the need for an alternate airport typically arises when the weather conditions at the destination airport do not meet the minimums for other operations or might deteriorate during the flight. For an airport to not require an alternate, the weather must meet the standard criteria set by the relevant authorities.

In this case, the conditions of 2000 feet overcast and 3 miles visibility are generally sufficient to allow visual flight rules (VFR) operations and typically meet the minimum requirements for a standard IFR flight where the destination airport is a reporting airport with those conditions. Therefore, if these conditions are maintained, an alternate airport is not required. This explains why the answer is that an alternate is not required under those specific weather conditions.
