The Federal Aviation Administration (FAA) Fixed Ground Antenna Radome (FGAR) Testand Evaluation Master Plan (TEMP) is prepared by the Program Manager (PM) andAssociate Program Manager for Test (APMT). It outlines the Test and Evaluation(T&E) process that will be used to ensure the project meets the requirements ofthe project specification and the system and subsystem requirements allocated tothe project. The FAA TEMP contains FGAR Operational Test and Evaluation (OT&E)test requirements and OT&E schedule durations.

The purpose of the FGAR project is to provide new and larger radomes for en routesurveillance radars that require collocated Mode Select Beacon System (Mode S)installations. As a result of the FAA's program to implement Mode S, many. existingen route surveillance radar radomes cannot accommodate the additional spacerequired by the new Mode S antennas. The FGARs will provide an environmentalenclosure for a variety of single or dual-face monopulse beacon phased array and enroute surveillance radar installations. Installations will be comprised of aninstallation mix ranging from beacon-only-sites (BOS) to collocated beacon and enroute surveillance radar sites.

1. PURPOSE.

The Federal Aviation Administration (FAA) Fixed Ground Antenna Radome (FGAR) Testand Evaluation Master Plan (TEMP) is the primary document on which related Test andEvaluation (T&E) activity is based. It is intended to be sufficiently detailed toallow FAA personnel associated with the FGAR program to prepare and review lowerlevel test planning documents, prepare for and conduct tests, review test data, andprepare reports. Its purpose is to provide the management and technicalinformation necessary to satisfy the requirements of the FAA mandated T&E processas outlined in Order 1810.4B. In addition, this plan is intended to be used as amanagement and technical tool which will allow the FAA to monitor the performanceof the T&E process, the quality and timeliness of planned tasks, and the overalladequacy of the products rendered during all phases of FGAR testing.

The FGAR is not a National Airspace System (NAS) major system acquisition (MSA).The FGAR contract (DTFA01-93-C-00075) was signed on September 30, 1993. The FGARspecification (FAA-E-2773b) establishes the requirements for performance, design,and acceptance of a state-of-the-art radome. There are no NAS requirements definedin NAS-SS-1000, NAS System Specification, or NAS-DD-lOOOE, National Airspace SystemLevel I Design Document. This document is prepared in accordance with FAA-STD-024a, Order 1810.4B, and NAS-MD-110 to the extent feasible for testing andevaluating non-MSA equipment.

3. DESCRIPTION.

This section reviews the aspects of the FGAR necessary for a successful T&Eprogram. Sufficient detail is provided to assure that cognizant T&E personnel willhave the knowledge to approach the tasks specified. There is no attempt to providean exhaustive knowledge of radome or radio frequency (RF) theory and measurement.

3.1 MISSION.

The mission of the FGAR project is to:

a. replace existing radomes on en route surveillance radar/Mode SelectBeacon System (Mode S)/Air Traffic Control Radar Beacon System (ATCRBS) towers.

b. install radomes on en route surveillance radar/Mode S/ATCRBS towers notcurrently covered.

c. replace existing radomes on Beacon Only Site (BOS) [Mode S/ATCRBS]

towers.

d. install radomes on BOS [Mode S/ATCRBS] towers not currently covered.

The FGAR will provide environmental protection for a sophisticated L bandantenna(s). The radome will be mounted on a fixed ground antenna tower and providean environmental enclosure for any of a variety of single or dual-faced monopulsephased array beacon and en route surveillance radar antennas. The radomes will benonmetallic (with the exception of fasteners), oblate spheroid or sphericallyshaped, and attached at the base to the antenna tower platform.

2

3.2 EQUIPMENT.

The FGAR supplies optimal protection of the antenna(s) from the outside environmentwhile providing minimal degradation to the electrical performance characteristicsof the enclosed antenna(s). There are five types of radomes; they are listedbelow. No Type IV radomes are being procured. All hardware required forinstallation: cables and wiring, support equipment, radome mounted/supportedequipment, radome mounting ring, spare parts, and the primary power, are part ofthe FGAR procurement.

The types of radomes are:

a. Tyve I Radome. This type of radome will provide an environmentalenclosure for a collocated L band surveillance radar parabolic reflector and top-mounted dual-faced L band beacon phased array antenna. The radome will be capableof withstanding wind velocities of 150 miles per hour (MPH). They will have aninside diameter of 59 feet at their widest point, and will fit a base ring diameterequal to the present CW-396A radome. The enclosed antennas will rotate at a speedof either 5 or 6 revolutions per minute (RPM).

b. Tyve II Radome. This type of radome will provide an environmentalenclosure for a dual-faced L band beacon phased array antenna consisting of twoidentical rectangular back-to-back antennas approximately 6 feet high by 27 feetwide, rotating at speeds up to 5 RPM. The radome will be capable of withstandingwind velocities of 150 MPH and will be 35 feet at its widest point. It will fitthe standard beacon-only antenna platform without requiring platform modification.

c. Type III Radome. This type of radome will be identical to the Type I inall respects, except that it shall be capable of withstanding wind velocities of100 MPH maximum.

d. TYre V Radome. This type of radome will provide an environmentalenclosure for a collocated L band radar reflector and top-mounted dual-faced L bandbeacon phased array antenna. The radome will be capable of withstanding windvelocities of 150 MPH. They will have an inside diameter of 57.5 feet at theirwidest point, and will fit a base ring diameter equal to the present Air RouteSurveillance Radar (ARSR)-3 [ESSCO Model M57-86-6000] radome.

e. Type VI Radome. This type of radome will be identical to the Type V inall respects, except that it shall be capable of withstanding wind velocities of100 MPH maximum.

Radome support equipment is defined in FAA-E-2773b.

The FGAR Remote Maintenance Monitoring Subsystem (RMMS) function will monitorenvironmental functions. The direct interface between the FGAR RMMS demarcationpoint, and an Environmental Remote Monitoring Subsystem (ERMS) planned for theradar site, will be in the radar equipment room.

3

3.2.1 Physical Description.

Each radome will be complete and include, but not limited to, the following:

a. Lightning protection assemblyb. Aircraft obstruction light assemblyc. Repair kit and maintenance itemsd. Zenith hatch assemblye. Service hatchf. Catwalk access hatchg. Interior safety ladderh. Interior block and tackle assemblyi. Crown vents, with remote actuation provisions via the ERMS/RMMS interfacej. Snow rope(s)

3.2.2 Key Functions.

The two key functions of FGAR are to protect the en route surveillance radar and/orthe Mode S antennas from the outside environment and not degrade their electricalperformance characteristics.

3.2.3 Interfaces.

The radome to tower interface is both physical and electrical. It is physicallyattached to the antenna tower by a radome mounting ring. The radome iselectrically interfaced with the radar electrical distribution system, lightningprotection system, aircraft obstruction lights, access hatches, RKNS/ERMS, andother devices/units necessary for operation and maintenance of the radome.

3.2.4 Unigue Characteristics.

The FGAR has no unique characteristics.

3.3 REQUIRED OPERATIONAL CHARACTERISTICS.

The FGAR will ensure the integrity of the en route surveillance and/or Mode Santennas spatially distributed electromagnetic radiation pattern in the frequencyband of 1000-1400 megahertz (MHz). It will maintain electromagnetic wavepolarization purity for vertical, horizontal, left, and right circular modes ofpolarization.

3.4 REQUIRED TECHNICAL CHARACTERISTICS.

The FGAR will provide an environmental enclosure for the en route surveillanceradar and/or Mode S antennas. The maximum allowable transmission loss is 0.2decibels (dB) in the frequency band of 1000-1400 MHz. The radomes are a rigidshell type assembly composed of dielectric panels. The materials used in theconstruction of the radome will withstand the environmental conditions in such away that weathering will not preclude its 20-year service life expectancy. Thephysical facility changes to support and interface each type of radome assemblywill be minimized.

4

The FGARs will replace many existing radomes in use today. This must beaccomplished without degrading NAS performance. The effects the FGAR has onantenna patterns, cross-polarization, gain, etc., will be evaluated to determine ifany degradation has occurred. This will be accomplished through test and analysis.The radome dielectric material characteristics will be evaluated to determine theeffects of weathering.

The ability to minimize transmission losses and maintain structural strength willbe included in the overall Operational Test and Evaluation (OT&E) testing.

There are three different physical sizes of FGARs. Depending on their geographicallocation, the radome will be designed to meet one of two different aerodynamic windloading requirements.

The FGAR will be used with the following types of antennas:

a. ARSR-IE and -IF

b. ARSR-2

c. ARSR-3

d. FPS AS-1561

e. Mode S En Route (Back-to-Back) Antenna

f. National Aviation Facilities Experimental Center (NAFEC) DipoleFeed (NADIF) Antenna

3.5 T&E ISSUES.

The FGAR T&E issues are those capability issues, either technical or operational,that must be examined before the FGAR's effectiveness can be determined. Thedevelopment of the concepts for testing these issues will be addressed in lowerlevel test documents. These issues will be of primary importance to the FAA inreaching a decision to deploy the FGAR.

The T&E will be conducted to determine if the move from the present radome, or insome cases no radome, to the FGAR can be accomplished without impacting the enduser.

4. PROGRAM SUMMARY.

The FGAR program management provides for a division of responsibilities between thevarious FAA organizations, its support contractors, and the FGAR contractor. TheFGAR contractur tasks and responsibilities are delineated in the contract andvarious agreements. The duties, responsibilities, and authority of various FAAorganizations are specified in applicable orders, and other documents, e.g.,program directives (PD), memorandum of understanding (MOU), etc., which may beissued. Authority for the expenditure of funds resides with the program manager(PM).

The FGAR T&E program consists of the processes that verify how well the FGAR meetsthe technical and operational requirements; provides data to assess acquisition,developmental, technical, and operational risks for decision making; verifiesperformance; and ensures that all critical issues to be evaluated by testing havebeen adequately considered and resolved.

The FAA Technical Center appointed Associate Program Manager for Test (APMT) hasthe overall responsibility for testing as delineated in the FAA Order 1810.4B. TheFGAR APMT resides in the Secondary Surveillance Systems Division, ACW-lO0. ACW-100is responsible for coordinating the T&E efforts vertically from the contractorthrough all FAA organizations and horizontally between FAA regions, FAA TechnicalCenter, FAA Logistics Center (FAALC), and the FAA Academy. The APMT's role beginsafter the program is initiated and concludes at the completion of the OperationalReadiness Demonstration (ORD) at the Type I, II, and V FGAR First Article sites.(The First Article sites are defined as the first three Type I sites and the firstType II and V sites.) The APHT tracks the program T&E status to the master T&Emilestones specified in the PD.

7

4.1 MANAGEMENT.

The FAA organizations required to support the T&E program and their responsi-bilities are detailed in Order 1810.4B. This order establishes a Test PolicyReview Committee (TPRC) and an FAA Technical Center APMT. The APMT acts as theagent of the PM and manages the T&E program.

The APMT will insure the program is conducted in accordance with the FAA T&Eorders. The APMT is responsible for the overall test program, and will prepareinputs for the PM for submission to the Deployment Readiness Review (DRR).

The APMT will develop the test plan and procedures for OT&E Integration testing andOT&E Operational testing. The APMT will review the plans and incorporate therequirements addressed into the program level Verification RequirementsTraceability Matrix (VRTM). (See appendix A).

Numerous FGAR T&E documents will be produced and issued by the contractor forreview by the FAA. The APMT will coordinate the review process of all ContractorData Requirement Lists (CDRL) relating to testing. A CDRL review tracking system,identifying critical and informational reviewers, will be generated for theprogram.

The NAS System Engineering Service (ASE) will be responsible for reviewing changesand updates to the TEMP through the FGAR acquisition phases.

A Quality Reliability Officer (QRO) may be appointed by the Associate Administratorfor Contracting and Quality Assurance (ASU-l) to monitor the DT&E and PAT&Etesting.

4.2 INTEGRIED SCHEDULE.

The schedules shown in this document are approximations due to the fluid nature ofthe program at the time of publication of this document. Nevertheless, they aregenerally sufficient for T&E planning purposes. A fully integrated schedule,showing the T&E program, will be developed by the program office and APMT usingMicrosoft Project as a tool.

The first site will be at the FAA Technical Center (Elwood ARSR site) and thesecond at the Northwest Mountain Regions Cascade, Idaho, ARSR site.

Activity summary charts are provided for ThE planning purposes (see figures 4.2-1through 4.2-3). These charts are used by the APMT for estimating relative level ofeffort, types of activity, and intensity of workload each T&E organization will beconfronted with during the overall T&E program.

The six major test milestones associated with this program are:

a. Contract awardb. Completion of Development Test and Evaluation (DT&E) testingc. Completion of Contract Acceptance Inspection (CAI)d. Completion of OT&E Integration testinge. Completion of OT&E Operational testingf. Completion of OT&E Shakedown testing

5.9 DT&E AND PAT&E RMA TEST ISSUES.

The majority of the RMA requirements, e.g., the mean time between critical failure(MTBCF) [175,200 hours], will be verified during DT&E testing, utilizing governmentapproved Reliability and Maintainability Program Plans. These contractor developedplans, prepared in accordance with applicable military standards (MIL-STD-781 and-785) and handbooks (MIL-HDBK-217 and -472), describe the methodology, equipmentconfigurations, models, etc., used to derive the reliability, maintainability, andavailability predictions for the FGAR and its subsystems.

16

6. OT&E INTEGRATION TESTING.

The OT&E Integration testing of the FGAR will be limited to testing the:

a. mechanical interface between the FGAR and the existing antenna tower.

b. interface between the FGAR environmental and equipment sensor(s) and theRMMS/ERMS.

The testing will be performed at the first site for Type I, II, and V FGARs.(Additional testing may be performed at the second and third Type I sites [whichare considered to be First Articles], if required.)

The mechanical interface between the FGAR and the existing antenna tower is theonly critical item.

7. OT&E OPERATIONAL TESTING.

The OT&E Operational testing will be conducted by ACW-1O0 at the first site forType I, II, and V FGARs. (Additional testing may be performed at the second andthird Type I sites [which are considered to be First Articles], if required.) TheOT&E Operational testing is performed to verify the requirements identified in theFAA TEMP VRTM. It verifies the FGAR does not degrade the performance of either theen route surveillance radar or Mode S antennas. In addition, it interfacesphysically and electrically with the existing tower structures. The OT&EOperational testing will begin immediately after the contractor completes DT&Etesting. The OT&E Operational test program will be structured to take fulladvantage of earlier DT&E testing.

7.1 OT&E OPERATIONAL TESTING OBJECTIVES.

The objectives of OT&E Operational testing are to:

a. verify the FGAR can replace the present radomes without degrading theelectromagnetic performance of the en route surveillance radar and/or the Mode Santennas.

b. verify the FGAR can provide environmental protection for the en routesurveillance radar and/or the Mode S antennas, and associated tower platformmounted equipment.

c. determine if there is sufficient personnel access to the radome forinspection and maintenance of the antenna(s) and tower mounted equipment.

d. determine if there is sufficient personnel access from the radome to thetower platform for inspection and maintenance purposes.

e. determine if there is sufficient personnel access from the radome to theaircraft obstruction light assembly and lightning protection system for inspectionand maintenance purposes.

17

f. determine impact of the FGAR on personnel safety.

g. determine if the FGAR mounted RMKS sensors will interface with theRMMS/ERKS.

h. determine if field maintenance, AOS-200, and FAALC support personnelreceived adequate training, in the contractor and/or FAA Academy conducted classes.

7.2 OT&E OPERATIONAL T&E TO DATE.

7.3 FUTURE OT&E OPERATIONAL TESTING.

Future OT&E Operational testing will include predelivery and First Article sitetesting as described below.

7.3.1 Predelivery Testing at FAA Technical Center.

The OT&E Operational testing will commence prior to delivery of the first FGAR.Various electromagnetic measurements will be made at the FAA Technical Center,Elwood ARSR site, with the present radome (an inflatable type) installed. Thesemeasurements will form the basis for comparison between the present inflatableradome and the FGAR.

7.3.2 Testing at First Article Sites.

Testing at the First Article Type I, II, and V FGAR sites will be divided intothree phases. During all three phases various electromagnetic measurements will bemade. Phase 1 will be conducted prior to the removal of the existing radome andthe installation by the contractor of any scaffolding, etc., required for itsremoval. Phase 2 will be conducted after the contractor has removed the currentradome, including any work scaffolding, crane boom, etc., required to remove theexisting radome. Phase 3 will be conducted after the installation of the FGAR iscompleted. During all three phases, the same electromagnetic measurements will bemade to allow a comparison between the existing radome, with no radome installed,and the FGAR. These tests will be made using an RF interference monitor (RFIM) vanand support personnel from ASM-500 and/or one of the FAA regions.

The SOW places the following time constraints on the Phase 2 and Phase 3 testing:

a. Phase 2 - 2 days

b. Phase 3 - 1 day (This phase must be successfully completed prior tofinal acceptance of the First Article FGARs.)

The results of Phases 1, 2, and 3 testing will be compared to ensure the FGAR doesnot exceed the allowable errors specified in FAA-E-2773b.

18

7.4 OT&E OPERATIONAL T&E EVENTS/SCOPE OF TESTING.

a. An RFIM van will be used to measure the antenna main lobe beam widtherror, boresight error, and sidelobe level error parameters of the antenna(s) asdefined in FAA-E-2773b. Other measurements may be made as determined necessary.

1. Prior to the removal of the present radome (if one is present).

2. After removal of the present radome.

3. After the complete installation and checkout of the FGAR by thecontractor, but prior to final acceptance by the government.

The RFIM van will be located at three points around the radar site periphery foreach phase of testing. Data recordings will be made at each location. At thecompletion of Phase 3, the results of Phases 2 and 3 will be compared to determineif the allowable errors have been exceeded. In addition, the results of Phases 1and 3 will be compared to determine if the FGAR has improved or degraded the enroute surveillance radar and/or Mode S antenna(s) performance.

In addition, a record of permanent echoes (PE) for both the en route surveillanceradar and Mode S will be made during all three phases, for determining theboresight error(s).

b. The ability of the FGAR to provide environmental protection for theantenna(s) will be evaluated utilizing actual, to the maximum extent possible, andsimulated weather conditions, e.g., water from high pressure hoses to simulate rainstorms, etc.

c. Access to the antenna tower, various FGAR mounted equipment, the outersurface of the radome, and the antenna(s) will be evaluated by having fieldmaintenance and FAALC support personnel perform various preventive and correctivemaintenance tasks.

d. Personnel safety will be evaluated to determine if:

1. There is sufficient lighting inside the radome for personnel tosafely perform preventive and corrective maintenance on the en route surveillanceradar and/or Mode S antenna(s) and other equipment mounted on the tower platformand at the zenith of the FGAR.

2. The interior safety ladder can be used without endangeringpersonnel.

3. The aircraft obstruction lights and lightning protection devices canbe serviced safely from the FGAR zenith service hatch.
