1、760 14 CFR Ch. I (1111 Edition) 170.21 170.21 Scope. This subpart sets forth establishment and discontinuance criteria for LORAN-C. 170.23 LORAN-C establishment cri-teria. (a) The criteria in paragraphs (a)(1) through (a)(6) of this section, along with general facility and navigational aid establish
2、ment requirements, must be met before a runway can be eligible for LORAN-C approach. (1) A runway must have landing sur-faces judged adequate by the FAA to accommodate aircraft expected to use the approach and meet all FAA-re-quired airport design criteria for non-precision runways. (2) A runway mus
3、t be found accept-able for instrument flight rules oper-ations as a result of an airport airspace analysis conducted in accordance with the current FAA regulations and provi-sions. (3) The LORAN-C signal must be of sufficient quality and accuracy to pass an FAA flight inspection. (4) It must be poss
4、ible to remove, mark, or light all approach obstacles in accordance with FAA marking and lighting provisions. (5) Appropriate weather information must be available. (6) Air-to-ground communications must be available at the initial ap-proach fix minimum altitude and at the missed approach altitude. (
5、b) A runway meets the establish-ment criteria for a LORAN-C approach when it satisfies paragraphs (a)(1) through (a)(6) of this section and the estimated value of benefits associated with the LORAN-C approach equals or exceeds the estimated costs (benefit- cost ratio equals or exceeds one). As defin
6、ed in 170.3 of this part, the ben-efit-cost ratio is the ratio of the present value of the LORAN-C life- cycle benefits (PVB) to the present value of LORAN-C life-cycle costs (PVC): PVB/PVC 1.0 (c) The criteria do not cover all situ-ations that may arise and are not used as a sole determinant in den
7、ying or granting the establishment of non-pre-cision LORAN-C approach for which there is a demonstrated operational or air traffic control requirement. 170.25 LORAN-C discontinuance cri-teria. A LORAN-C nonprecision approach may be subject to discontinuance when the present value of the continued ma
8、intenance costs (PVCM) of the LORAN-C approach exceed the present value of its remaining life-cycle bene-fits (PVB): PVB/PVCM 2010 08:29 Feb 24, 2011 Jkt 223045 PO 00000 Frm 00770 Fmt 8010 Sfmt 8010 Y:SGML223045.XXX 223045WReier-Aviles on DSKGBLS3C1PROD with CFRProvided by IHSNot for ResaleNo reprod

(a) The following are the minimum requirements that must be met before the FAA will approve an IFR procedure for a non-Federal VOR: (1) The facilitys performance, as d
24、e-termined by air and ground inspection, must meet the requirements of 171.7. (2) The installation of the equipment must meet the requirements of 171.9. (3) The owner must agree to operate and maintain the facility in accord- ance with 171.11. (4) The owner must agree to furnish periodic reports, as

26、of this sec-tion and of any flight or ground inspec-tions made before the facility is com-missioned, except that the Federal Aviation Administration may bear cer-tain of these costs subject to budgetary limitations and policy established by the Administrator. (b) If the applicant for approval meets
27、the requirements of paragraph (a) of this section, the FAA commis-sions the facility as a prerequisite to its approval for use in an IFR proce-dure.

29、hat part of paragraph 3.3.2.1 specifying a radio frequency tolerance of 0.005 percent, and that part of para-graph 3.3.7 requiring removal of only the bearing information. In place thereof, the frequency tolerance of the radio frequency carrier must not ex-ceed plus or minus 0.002 percent, and all r
30、adiation must be removed during the specified deviations from estab-lished conditions and during periods of monitor failure. (b) Ground inspection consists of an examination of the design features of the equipment to determine that there will not be conditions that will allow unsafe operations becau
31、se of compo-nent failure or deterioration. (c) The monitor is checked periodi- cally, during the in-service test evalua-tion period, for calibration and sta-bility The tests are made with a stand-ard Reference and variable phase sig-nal generator and associated test equipment, including an oscillosc
32、ope and portable field detector. In general, the ground check is conducted in accord- ance with section 8.4 of FAA Handbook AF P 6790.9 Maintenance In-struction for VHF Omniranges, adapt-ed for the facility concerned. (d) Flight tests to determine the fa-cilitys adequacy for operational re-quirement
33、s and compliance with appli-cable Standards and Recommended Practices are conducted in accordance with the U.S. Standard Flight Inspec-tion Manual, particularly section 201.

In addition, at low traffic density airpo
42、rts within or immediately adjacent to controlled airspace and where extensive delays are not a fac-tor, the requirements of paragraphs (e) (1) and (2) of this section may be re-duced to reliable communications (at least a landline telephone) from the airport to the nearest FAA air traffic control or
43、 communication facility, if an adjacent FAA facility can commu-nicate with aircraft during the pro-posed instrument approach procedure, at least down to the minimum en route altitude for the controlled airspace area.
