What is the IFR Takeoff minimum visibility for aircraft with more than 2 engines?

The takeoff minimum visibility for aircraft with more than two engines is indeed 1/2 statute mile (sm). According to the Federal Aviation Administration (FAA) regulations, specifically under 14 CFR Part 91.175, aircraft that are equipped with more than two engines can operate when visibility is as low as 1/2 sm when taking off under Instrument Flight Rules (IFR). This visibility minimum is established to facilitate a balance between safety and operational capability, allowing these aircraft some flexibility in poor weather conditions due to their enhanced performance and redundancy offered by multiple engines.

In contrast, single-engine and certain smaller multi-engine aircraft often face stricter visibility requirements such as 1 sm, underscoring the differences in operational capability and safety margins. This is why maintaining a clear understanding of these regulations for various aircraft classifications is crucial for pilots operating under IFR.
