A fuel sample should be taken prior to the 1st Flight of the day.

• A. 1st Flight
• B. First Flight
• C. Pre-Flight
• D. Opening Flight

Answer: (A)

Taking a fuel sample is a safety check that should happen before operations begin for the day. Collecting the sample prior to the first flight ensures any issues with fuel quality—like water or contaminants—are detected before any aircraft takes off, so you don’t start a day with potentially unsafe fuel.

The exact wording used in procedures is typically concise and uses the abbreviation for “first” in this context. So the option that matches “prior to the 1st Flight of the day” is the one that uses 1st Flight. The other choices don’t fit this specific timing phrase: First Flight is close but not the standardized wording, Pre-Flight refers to checks done before any flight, not specifically the first flight of the day, and Opening Flight isn’t standard terminology.
