WAAS capable receivers utilize an additional two geostationary WAAS satellites that are positioned over North America. The two additional WAAS satellites work in conjunction with several ground stations located throughout the USA. The WAAS ground stations work to interpret the existing GPS satellite constellation signals and make corrections to any errors that may exist. Errors from GPS satellites include satellite orbital errors, ionospheric disturbances, and timing. The WAAS ground stations make corrections to those errors and send them up to the two geostationary satellites. From there, WAAS satellites repeat the correction signal down to WAAS capable receivers. Using WAAS capable receivers provides improved accuracy typically better than 9 feet. Compared to the existing standard GPS signal, WAAS corrected GPS signals offer approximately 5 times greater position accuracy. Up until WAAS came along, GPS systems were capable of delivering non-precision approaches only. Using non precision approaches in less than desirable weather conditions could end in a missed approach due to low ceilings and lead to the flight terminating at an alternate airport. Now, with the addition of a WAAS capable receiver, LPV (Localizer Performance with Vertical Guidance) approaches can be accomplished with minimums as low as 200 feet agl. An LPV approach is very similar to the ILS. The LPV approach functions the same but with greater accuracy and precision. GPS precision approaches are now a thing of today.

Most business oriented aircraft operations are conducted from non ILS airports and are restricted to use non precision approaches. Use of the precision LPV approach could make the difference in diverting to the alternate. Greater fuel savings due to reduced diversions to alternate airports.

Using the "ILS" like approaches that LPV offers can reduce pilot stress and error related issues associated with non precision approaches.

The virtual highways create more pathways for today's congested National Airspace System allowing smoother flow of air traffic and less restrictions for traffic control. The results of these new corridors or highways save time, fuel and money. Flight Management Systems are used to navigate RNP procedures. The GPS / IRS / INS systems are used by the FMS to calculate the precision "corridor" or "highway" of an RNP procedure.

The RNP Value is a lateral width figure. RNP Values are shown as nautical miles such as "RNP 0.3". RNP values will vary with different approaches as required due to the physical characteristics of the approach. To execute the RNP approach requires an "SAAAR" approval from the FAA. SAAAR is short for "Special Aircraft and Aircrew Authorization Required" An excellent example of the RNP approach can be seen at Palm Springs International Airport in California (PSP) "RNAV (RNP) RWY 13R". Through the use of GPS, a precision approach can be incorporated into the mountainous terrain that surrounds the airport. Aircraft operators may apply for RNP approval thru the FAA. RNP authorizations are issued depending on the individual operators operational procedures and aircraft qualifications. Your local FSDO will issue a LOA with appropriate documentation approval.
