BAC stands for what?

• A. Before Landing Checklist
• B. Before Auto Landing Check
• C. Before Approach Circuit
• D. Before Lateral Cue

Answer: (A)

This item tests recognizing the standard phrase used for the landing phase. BAC in this context stands for the Before Landing Checklist, the routine set of checks pilots perform to confirm the aircraft is properly configured for landing. It is the moment to verify gear down and locked, flaps and speed settings, landing lights on, and other critical items are set before you touch down. The other options aren’t standard terms used for this phase of flight: there isn’t a commonly used “Before Auto Landing Check,” “Before Approach Circuit” refers to a different phase or procedure, and “Before Lateral Cue” isn’t a recognized checklist at all. Remember that outside aviation, BAC often means Blood Alcohol Content, but in flight operations the expected acronym for preparing to land is Before Landing Checklist.
