Which of the following is required for every flight under Part 135?

The requirement that all necessary emergency equipment must be available for each flight under Part 135 is crucial for ensuring safety and compliance with federal aviation regulations. Part 135 governs the operation of commuter and on-demand airline services. This regulation mandates that appropriate safety equipment is not only present but also in working condition before the flight commences.

The availability of emergency equipment, such as life vests, emergency first aid kits, fire extinguishers, and survival gear, is essential to protect passengers and crew in the event of an emergency. Having this equipment readily on hand can significantly enhance the ability to manage unforeseen situations, thereby reducing the risk of serious incidents during flight operations.

In summary, the emphasis on maintaining available and functional emergency equipment underscores the priority that aviation regulations place on the safety and preparedness of all flights, which is vital for both regulatory compliance and ensuring the well-being of everyone on board.
