Aircraft shall be separated at a minimum of ___ feet until visual separation can be maintained.

Visual separation is what you rely on once both aircraft can see each other and keep clear of one another without ATC guidance. Until that visual contact is established, ATC maintains a safe margin using instrument-based separation. The five-hundred-foot minimum is the value used to ensure a modest, safe gap during the transition to visual separation in busy terminal areas. Once pilots have the other aircraft in sight and can maintain separation visually, the controller can reduce or discontinue the instrument-based separation. The other numbers don’t align with this transitional safeguard in typical ATC procedures, so five hundred feet is the standard threshold for this situation.
