Which statement describes when a pre-flight instruction is required?

• A. Only during boarding
• B. Prior to the first flight on an aircraft
• C. Anytime the aircraft has been left unattended
• D. Prior to the first flight on an aircraft, anytime the aircraft has been left unattended, after flight attendant change or aircraft swap

Answer: (D)

Pre-flight instruction is required anytime there could be a change or lapse that affects safety: before the first flight on that aircraft, whenever the aircraft has been left unattended, and after a flight attendant change or an aircraft swap. This ensures every crew member knows the current safety procedures, location of exits and equipment, and any aircraft-specific differences for that flight. The other options are too narrow—boarding alone doesn’t cover unattended periods or crew changes, and just before the first flight doesn’t address scenarios where the aircraft has been left unattended or where a crew member or aircraft configuration changed. The comprehensive statement captures all the situations where a fresh briefing is necessary.
