In addition to subpara e, separatean aircraft landing behind another aircraft on thesame runway, or one making a touch-and-go,stop-and-go, or low approach by ensuring thefollowing minima will exist at the time the precedingaircraft is over the landing threshold:NOTE−Consider parallel runways less than 2,500 feet apart as asingle runway because of the possible effects of waketurbulence.1. Small behind large− 4 miles.2. Small behind B757− 5 miles.3. Small behind heavy− 6 miles.g. TERMINAL. 2.5 nautical miles (NM) separationis authorized between aircraft established on thefinal approach course within 10 NM of the landingrunway when operating in single sensor slant rangemode and aircraft remains within 40 miles of theantenna and:1. The leading aircraft’s weight class is the sameor less than the trailing aircraft;2. Heavy aircraft and the Boeing 757 arepermitted to participate in the separation reduction asthe trailing aircraft only;3. An average runway occupancy time of50 seconds or less is documented;4. CTRDs are operational and used for quickglance references;REFERENCE−FAAO 7110.65, Use of Tower Radar Displays, Para 3−1−9.5.

VERTICAL APPLICATIONAircraft not laterally separated, may be verticallyseparated by one of the following methods:a. Assign altitudes to aircraft, provided validMode C altitude information is monitored and theapplicable separation minima is maintained at alltimes.REFERENCE−FAAO 7110.65, Vertical Separation Minima, Para 4−5−1.FAAO 7110.65, Validation of Mode C Readout, Para 5−2−17.FAAO 7110.65, Separation, Para 7−7−3.FAAO 7110.65, Separation, Para 7−8−3.FAAO 7110.65, Separation, Para 7−9−4.b. Assign an altitude to an aircraft after the aircraftpreviously at that altitude has been issued aclimb/descent clearance and is observed (validMode C), or reports leaving the altitude.NOTE−1. Consider known aircraft performance characteristics,pilot furnished and/or Mode C detected information whichindicate that climb/descent will not be consistent with therates recommended in the AIM.2. It is possible that the separation minima described inpara 4−5−1, Vertical Separation Minima, para 7−7−3,Separation, para 7−8−3, Separation, or para 7−9−4,Separation, might not always be maintained usingsubpara b. However, correct application of this procedurewill ensure that aircraft are safely separated because thefirst aircraft must have already vacated the altitude priorto the assignment of that altitude to the second aircraft.REFERENCE−FAAO 7110.65, Procedural Preference, Para 2−1−3.FAAO 7110.65,Vertical Separation Minima, Para 4−5−1.FAAO 7110.65,Validation of Mode C Readout, Para 5−2−17.FAAO 7110.65, Application, Para 6−6−1.5−5−6.
