Sec. 170.23  LORAN-C establishment criteria.



    (a) The criteria in paragraphs (a)(1) through (a)(6) of this 

section, along with general facility and navigational aid establishment 

requirements, must be met before a runway can be eligible for LORAN-C 

approach.

    (1) A runway must have landing surfaces judged adequate by the FAA 

to accommodate aircraft expected to use the approach and meet all FAA-

required airport design criteria for nonprecision runways.

    (2) A runway must be found acceptable for instrument flight rules 

operations as a result of an airport airspace analysis conducted in 

accordance with the current FAA regulations and provisions.

    (3) The LORAN-C signal must be of sufficient quality and accuracy to 

pass an FAA flight inspection.

    (4) It must be possible 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 

approach fix minimum altitude and at the missed approach altitude.

    (b) A runway meets the establishment 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 defined in Sec. 170.3 of this part, the benefit-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 situations that may arise and are 

not used as a sole determinant in denying or granting the establishment 

of non-precision LORAN-C approach for which there is a demonstrated 

operational or air traffic control requirement.
