Separate aircraft operating in oceanic airspace, above FL 450 between a supersonic and any other aircraft by ____ feet.

When aircraft are operating in oceanic airspace and one is supersonic, a larger vertical separation is required to account for the higher speeds and the limited surveillance and communication typical in that environment. Above flight level 450, the required vertical separation between a supersonic aircraft and any other aircraft is 4,000 feet. This extra margin helps ensure safe resolution of any maneuver or course change and provides a buffer in areas where radar coverage and coordination are less precise. The other options would not provide enough separation for this high-speed, high-altitude pairing.
