These criteria will be affected through a change to FAA Order 7031.2C, Airway Planning Standard Number One (APS-1). APS-1 contains the policy and summarizes the criteria used in determining eligibility of terminal locations for establishment, discontinuance and improvements of air navigation facilities and air traffic control services. Applying the RVR benefit/cost criteria to 470 Category I runways at 359 airport traffic control tower locations identifies 103 airports satisfying the criteria for an initial Category I Touchdown RVR and 107 airports satisfying the criteria for both a first and second Category I Touchdown RVR, for a total of 317 qualifying runways. However, since benefit/cost criteria are but one of several inputs to the FAA decision-making process relative to investment in airport facilities and equipment, the ultimate site-specific investment action must be based on all pertinent factors and considerations. Sensitivity of the criteria results to several key assumptions is also examined. Keywords: Instrument landing system; Microwave landing system; Investment criteria; Capital budgeting. (EDC) 收起
