What must be ensured before and after the application of visual separation?

• A. VFR conditions
• B. Other approved separation
• C. Weather advisories
• D. Wake turbulence advisories

Answer: (B)

Before and after applying visual separation, it is crucial to ensure that other approved separation criteria are maintained. This is because visual separation does not replace standard separation methods but instead complements them. Maintaining other approved separation ensures that there is a robust and reliable safety margin between aircraft, as visual separation relies on pilots and air traffic control's ability to see and maneuver the aircraft according to visual cues.

While VFR conditions, weather advisories, and wake turbulence advisories are important considerations in air traffic management, they do not inherently guarantee safe separation. VFR conditions might not always be met, thus potential issues could arise if visual separation were relied upon exclusively. In summary, ensuring other approved separation before and after visual separation is essential for maintaining safety during air traffic operations.
