What limitation is imposed on CPL holders after September 1, 2015?

The limitation imposed on CPL holders after September 1, 2015, specifically pertains to the requirement for a Multi-Crew Cooperation (MCC) course. This regulation emphasizes the necessity for CPL holders to have appropriate training when flying in a multi-crew environment, reflecting the importance of teamwork and coordination in aircraft operations that involve multiple pilots working together. The MCC course ensures that pilots are adequately prepared to function effectively in such settings, covering crucial aspects like communication, decision-making, and crew resource management.

The other options, while they may highlight important regulations in aviation, do not align with the specific limitation introduced on the indicated date. For instance, the requirement for night flying usually depends on individual pilot qualifications and does not apply universally to all CPL holders based on the 2015 regulation. Similarly, flight reviews and passenger transport are governed by other existing rules, which may or may not correlate to the specific limitations imposed after September 2015. The operational weight limitations, in general, pertain to different categories of licenses instead of being a specific constraint added for CPL holders at that time.
