What are routine SRSL callouts during approach?

The routine SRSL callouts during approach typically focus on key milestones and safety checks that provide essential situational awareness to the flight crew. "On Runway XX," indicates that the aircraft is aligned with the designated runway, confirming to all crew members that they are on the correct path for landing, and is crucial for ensuring proper runway management and safety. The callout "One hundred remaining" signifies that the aircraft is 100 feet above the ground, which serves as a critical reminder of the altitude during the final stages of approach, allowing for necessary adjustments in speed and configuration as the aircraft prepares to land.

These callouts are integral to maintaining effective communication and enhancing safety, helping the flight crew stay coordinated and aware of their progress during the landing process. Other options may include relevant phrases, but they do not align as closely with standard industry practices for routine approach callouts, which prioritize clarity and crucial safety indicators during the landing sequence.
