What must you verify prior to fueling an aircraft?

Prior to fueling an aircraft, it is essential to ensure that the aircraft is properly prepared to mitigate safety risks associated with the fueling process. This involves verifying that the aircraft is chocked, which prevents it from moving unexpectedly, and grounded, ensuring any static electricity is discharged to avoid ignition. Additionally, checking that all safety pins are installed is crucial as they help secure various mechanisms and systems during ground operations.

Ensuring that the vent tank wet light is operational allows for monitoring potential fuel spills or overfills, which can be hazardous. Finally, having a fire bottle watch present is vital for immediate response in case of a fire incident during fueling. This comprehensive check of safety measures is critical for maintaining operational safety and preventing accidents during fueling operations.
