Before commencing an ETOPS flight, what must be certified by a PDSC Signatory person?

For an ETOPS (Extended-range Twin-engine Operational Performance Standards) flight, it is essential that a pre-departure service check is certified by a PDSC Signatory person. This process ensures that the aircraft meets the required operational standards for extended flights over water or remote areas where diversion options are limited.

The pre-departure service check involves a thorough review and confirmation that all systems, equipment, and functionalities necessary for safe operation during the flight are in optimal condition. This includes checking emergency equipment, fuel levels, navigation systems, and other critical components that are vital for the safety of an ETOPS flight. By having a qualified signatory confirm this check, it ensures that the airline adheres to rigorous ETOPS regulatory standards, thereby safeguarding passengers and crew on these long-haul operations.

The focus on this certification emphasizes the importance of thorough preparation and compliance specific to ETOPS, where the safety margin is tightly regulated due to the nature of the routes involved.
