“…The RNP AR approach procedure is a high-performance RNP procedure, which is of great value for ensuring take-off and landing safety of civil aircraft at high-plateau airports or some special airports [6,7]. The advantages of RNP AR can be summarized as follows: 1 It can effectively reduce the impact of obstacles via a flexible horizontal trajectory to increase the take-off weight [8].…”

RNP AR is an operational procedure that uses the aircraft’s airborne navigation equipment and global positioning system to guide the aircraft to take off and land, and it is an effective means to ensure the flight safety of civil aircraft at high-plateau environments. In this paper, a three-dimensional, precise guidance command generation method for performing an RNP AR approach procedure is proposed. The lateral navigation transition paths between different segments are constructed, and a lateral segment switching strategy based on the angular bisector is introduced. To illustrate the availability of the proposed algorithm, a simulation based on the RNP AR approach procedure of Jiuzhai Huanglong Airport is operated, and it can be drawn from the results that the proposed algorithms can provide lateral and vertical guidance capabilities that meet the requirements of RNP AR approach.

“…Navigation abilities unique to RNP AR procedures are not available with any other instrument approach procedures; however, these procedures are not widely used due to the high costs associated with their operation. In the U.S., the use of RNP procedures varies widely between airports, ranging from 0.3% at Seattle/Tacoma to 7.56% at New York/JFK [5]. As their implementation is very recent and not all airlines have the capacity to operate it [5], few studies have focused on quantifying the benefits of operating RNP procedures [4,6,7].…”

Performance-Based Navigation Flight Path Analysis Using Fast-Time Simulation

The growing demand for air transportation has led to an increase in worldwide air traffic inefficiency due to capacity constraints. The impacts associated with this situation can be reduced through operational changes. To better handle the problem, the Single European Sky ATM Research (SESAR) and the Next Generation Air Transportation System (NextGen) program suggest Performance-Based Navigation (PBN) as a solution. The Area Navigation (RNAV) and Required Navigation Performance (RNP) approaches belong to the group of PBN procedures. These procedures allow for a more efficient use of airspace by reducing route distances, fuel consumption and perceived aircraft noise. This article quantifies the benefits of PBN systems for two indicator parameters—fuel burn and flight time—and compares PBN systems to conventional instrument navigation procedures. The case studies use five airports in Brazil. The results of this analysis show that the benefits of the PBN approach vary with aircraft type and individual route characteristics.
