What does DE1 signify in service preparation?

• A. Ready to go (prep and checks)
• B. Come this way (boarding)
• C. Let's go (after takeoff and service prep)
• D. Wine and dine (service overview and clearance)

Answer: (A)

DE1 signifies "Ready to go (prep and checks)" in service preparation. This term is crucial as it indicates the stage where all necessary preparations and checks have been completed, ensuring that the service is ready to begin smoothly. It encompasses final confirmations that safety checks have been conducted, equipment is in place, and the crew is prepared for any contingencies. Success at this stage is essential for maintaining high standards in aviation service, as it sets the foundation for a safe and efficient flight experience.

The other choices involve actions that occur after the DE1 stage, focusing more on what happens during or after boarding and in-flight services rather than the initial readiness and preparation phase that DE1 signifies.
