What are the civil takeoff minimums for an aircraft with two engines or more?

In IFR operations, the civil takeoff minimums for an aircraft with two engines or more are specified as ½ statute mile visibility. This minimum, established by the FAA, is designed to enhance safety during departures from airports when the weather conditions are not ideal. The rationale behind this specific takeoff minimum lies in the increased performance capabilities of multi-engine aircraft, allowing them to operate safely in lower visibility conditions compared to single-engine aircraft.

The requirements for takeoff visibility can vary based on the number of engines, and for aircraft with two or more engines, the regulations acknowledge the greater maneuverability and reliability offered by their engine configuration. Thus, pilots operating such airplanes can utilize the lower visibility minimums as they have higher climb performance and redundancy.

This standard represents a balance between operational practicality and safety considerations, ultimately aiming to maintain an appropriate level of safety for flight operations in varying weather conditions.
