How many hours of training are required for a commercial multi add-on?

For obtaining a commercial multi-engine add-on rating, the Federal Aviation Administration (FAA) regulations typically require a minimum of 20 hours of multi-engine flight training. This training must include specific areas of focus such as aircraft systems, flight maneuvers, and emergency procedures in a multi-engine environment.

The 20 hours ensure that the pilot gains adequate experience and proficiency in handling the complexities of multi-engine operations, including managing engine failures and understanding the performance characteristics unique to multi-engine aircraft. In addition to the required flight training, the pilot must also accumulate a minimum number of logged flight hours and demonstrate the ability to perform various flight maneuvers, ensuring a comprehensive understanding of multi-engine flying safety and skill.

This regulatory framework is designed to enhance safety and competency among pilots transitioning to multi-engine flying, making the 20-hour requirement a standard that reflects the added challenges associated with operating aircraft with two or more engines.
