For jets and turboprop aircraft, vertical separation may be reduced to _______ feet when inside 12 miles.

Vertical separation minima can be tightened in the terminal environment when radar surveillance and precise altitude-keeping are available, to increase capacity without sacrificing safety. For jets and turboprop aircraft inside 12 miles, the published reduced minimum is 800 feet, instead of the standard 1000 feet. This reduction relies on active radar monitoring and the ability of both aircraft to maintain exact altitudes under positive control, which allows controllers to confidently space aircraft more tightly as they approach or depart busy areas. The other numbers don’t match the allowed reduced minimums in this scenario: 600 feet isn’t the published value for this case, 1000 feet is the typical minimum outside the reduced area, and 1200 feet would be more conservative than the reduced standard.
