2/19/047110.65PChapter 5. RadarSection 1. General5−1−1. PRESENTATION AND EQUIPMENTPERFORMANCEProvide radar service only if you are personallysatisfied that the radar presentation and equipmentperformance is adequate for the service beingprovided.NOTE−The provision of radar service is not limited to the distanceand altitude parameters obtained during the commissioningflight check.5−1−2. ALIGNMENT ACCURACY CHECKDuring relief briefing, or as soon as possible afterassuming responsibility for a control position, checkthe operating equipment for alignment accuracy anddisplay acceptability. Recheck periodically throughoutthe watch.REFERENCE−FAAO 7210.3, Chapter 3, Chapter 8, Chapter 9, Chapter 10, andChapter 11.Comparable Military Directives.TERMINALa. Check the alignment of the radar video displayby assuring that the video/digital map or overlay isproperly aligned with a permanent target of knownrange and azimuth on the radar display. Wherepossible, check one permanent target per quadrant.b. Accuracy of the radar video display shall beverified for digitized radar systems by using themoving target indicator (MTI) reflectors, fixedlocation beacon transponders (Parrots), beaconreal−time quality control (RTQC) symbols orcalibration performance monitor equipment (CPME)beacon targets.REFERENCE−FAAO 7210.3, Tolerance for Radar Fix Accuracy, Para 3−8−1.c. STARS equipment conducts continuous self−monitoring of alignment accuracy; therefore, controlleralignment checks are not required.EN ROUTEd. When operating in the narrowband mode(Stage A) alignment checking is accomplished by theoperational program as part of the certificationprocedures for system startup and then on a real−timebasis during operational hours.e. When operating in the EDARC/DARC/HOSTor EDARC/DARC mode, ensure the PVD/MDMcenter and altitude limits for the system areappropriate for the operating position.REFERENCE−FAAO 7110.65, Selected Altitude Limits, Para 5−14−5.MEARTSf. The operational program accomplishes alignmentchecking. Verification of accuracy shall beaccomplished through the use of “targets ofopportunity” over displayed fixes, navigational aids,etc., in accordance with provisions of FAAO 7210.3,para 8−3−1, Digital Map Verification.5−1−3. RADAR USEUse radar information derived from primary andsecondary radar systems.REFERENCE−FAAO 7110.65, Beacon Range Accuracy, Para 5−1−4.FAAO 7110.65, Inoperative or Malfunctioning Interrogator,Para 5−2−15.a. Secondary radar may be used as the sole displaysource as follows:1. In Class A airspace.REFERENCE−FAAO 7110.65, Failed Transponder in Class A Airspace, Para 5−2−16.14 CFR Section 91.135, Operations in Class A Airspace.2. Outside Class A airspace, or where mix ofClass A airspace/non−Class A airspace exists, onlywhen:(a) Additional coverage is provided bysecondary radar beyond that of the primary radar.(b) The primary radar is temporarily unusableor out of service. Advise pilots when these conditionsexist.PHRASEOLOGY−PRIMARY RADAR OUT OF SERVICE. RADAR TRAFFICADVISORIES AVAILABLE ON TRANSPONDERAIRCRAFT ONLY.General5−1−1
