What is the minimum cross-country flight requirement for a commercial multi add-on?

The minimum cross-country flight requirement for a commercial multi-engine add-on is 300 hours. This requirement reflects the need for sufficient experience and proficiency in handling complex aircraft, which multi-engine planes typically are. The rationale behind this high threshold is to ensure that pilots have adequate exposure to diverse flight conditions and scenarios, allowing them to develop the necessary skills to operate safely and effectively.

The requirement of 300 hours indicates a commitment to rigorous training and experience, as this level of flight time enables pilots to handle the additional complexities associated with multi-engine aircraft, such as engine-out situations, performance considerations, and advanced navigation techniques. Training for a commercial pilot license, especially with a multi-engine endorsement, emphasizes safety and competence, thereby enhancing overall aviation safety standards.

The other options reflect lower minimum flight hours that do not meet the specific training and experience requirements mandated for the commercial multi-engine add-on endorsement. Requirements are designed to ensure that pilots are fully prepared for the unique challenges of multi-engine flying.
