7110.65P 2/19/045−9−7. SIMULTANEOUS INDEPENDENTILS/MLS APPROACHES− DUAL & TRIPLETERMINALa. Apply the following minimum separation whenconducting simultaneous independent ILS, MLS, orILS and MLS approaches:1. Provide a minimum of 1,000 feet vertical ora minimum of 3 miles radar separation betweenaircraft during turn-on to parallel final approach.NOTE−1. During triple parallel approaches, no two aircraft willbe assigned the same altitude during turn-on. All threeaircraft will be assigned altitudes which differ by aminimum of 1,000 feet. Example: 3,000, 4,000, 5,000;7,000, 8,000, 9,000.2. Communications transfer to the tower controller’sfrequency shall be completed prior to losing verticalseparation between aircraft.2. Dual parallel runway centerlines are at least4,300 feet apart.3. Triple parallel runway centerlines are at least5,000 feet apart and the airport field elevation is lessthan 1,000 feet MSL.4. A high-resolution color monitor with alertalgorithms, such as the final monitor aid or thatrequired in the precision runway monitor programshall be used to monitor approaches where:(a) Triple parallel runway centerlines are atleast 4,300 but less than 5,000 feet apart and theairport field elevation is less than 1,000 feet MSL.(b) Triple parallel approaches to airportswhere the airport field elevation is 1,000 feet MSL ormore require the high resolution color monitor withalert algorithms and an approved FAA aeronauticalstudy.5. Provide the minimum applicable radarseparation between aircraft on the same finalapproach course.REFERENCE−FAAO 7110.65, Minima, Para 5−5−4.b. The following conditions are required whenapplying the minimum separation on adjacent dual ortriple ILS/MLS courses allowed in subpara a:1. Straight-in landings will be made.2. ILS, MLS, radar, and appropriate frequenciesare operating normally.3. Inform aircraft that simultaneous ILS/MLSapproaches are in use prior to aircraft departing anouter fix. This information may be provided throughthe ATIS.4. Clear the aircraft to descend to theappropriate glideslope/glidepath intercept altitudesoon enough to provide a period of level flight todissipate excess speed. Provide at least 1 mile ofstraight flight prior to the final approach courseintercept.NOTE−Not applicable to curved and segmented MLS approaches.5. An NTZ at least 2,000 feet wide is establishedan equal distance between extended runway finalapproach courses and shall be depicted on themonitor display. The primary responsibility fornavigation on the final approach course rests with thepilot. Control instructions and information are issuedonly to ensure separation between aircraft and toprevent aircraft from penetrating the NTZ.6. Monitor all approaches regardless of weather.Monitor local control frequency to receive anyaircraft transmission. Issue control instructions asnecessary to ensure aircraft do not enter the NTZ.NOTE−1. Separate monitor controllers, each with transmit/receiveand override capability on the local controlfrequency, shall ensure aircraft do not penetrate thedepicted NTZ. Facility directives shall define responsibilityfor providing the minimum applicable longitudinalseparation between aircraft on the same final approachcourse.2. The aircraft is considered the center of the primaryradar return for that aircraft, or, if an FMA or other colorfinal monitor aid is used, the center of the digitized targetof that aircraft, for the purposes of ensuring an aircraftdoes not penetrate the NTZ. The provisions of para 5−5−2,Target Separation, apply also.c. The following procedures shall be used by thefinal monitor controllers:1. Instruct the aircraft to return to the correctfinal approach course when aircraft are observed toovershoot the turn-on or to continue on a track whichwill penetrate the NTZ.5−9−8Radar Arrivals
