What is the minimum number of night takeoffs and landings required for a commercial multi add-on?

For a commercial pilot's multi-engine add-on rating, the regulations specify that a pilot must have a minimum of 10 night takeoffs and landings. This requirement is in place to ensure that pilots gain sufficient experience and proficiency in handling multi-engine aircraft during nighttime operations, which involves additional challenges such as reduced visibility and altered spatial orientation. Achieving this minimum will help to build the necessary skills and confidence required to operate safely in the multi-engine environment after dark. Thus, the requirement for 10 night takeoffs and landings is set within the regulatory framework for commercial multi-engine operations.
