USER PREFERRED ROUTES IN LIMA FIR

 

1. Purpose

1.1.    The purpose of this Aeronautical Information Circular (AIC) is to disseminate to all personnel involved in air operations a series of user preferred routes that may be filed in their flight plan and used by Air Traffic Control in the clearance.

1.2.    By definition, a User Preferred Route (UPR) is a unique flight path that aircraft operators can flight plan and fly instead of following the conventional, predetermined aviation routes published by air navigation service providers.

1.3.    The personnel responsible for the preparation and presentation of flight plans (Aircraft Operators or Pilots) are responsible for complying with the provisions of this AIC.

 

2. Introduction

2.1.    The ICAO Global Air Navigation Plan (GANP) and Aviation System Block Upgrades (ASBU) methodology provide a flexible, global approach for all aviation stakeholders to advance their Air Navigation capacities based on their specific operational requirements. ASBU FRTO Block 0 Element 1 (B0/1, Direct routing (DCT) states that DCTs are established at national and regional levels and can be made available for flight planning within the published conditions of use. DCTs should be considered an early iteration of the FRA concept of operation that allow airspace users to optimize flight and fuel planning.

2.2.    While the implementation of the broader concept of DCT routing is still being developed, it is operationally important to take advantage of opportunities to implement user preferred routes for filing flight plans, which consist of the most optimized routes possible according to the technical/operational capabilities of the involved ANSPs.

2.3.    ICAO NACC Airspace Optimization Task Force, ICAO SAM Airspace Study and Implementation Group (GESEA), CANSO (CADENA), and IATA have identified opportunities to achieve fuel savings and reduce CO2 emissions by working collaboratively to help optimize a flight’s end-to-end routing. In today’s environment, after the flight plan has been filed and the aircraft is enroute, pilots will often receive “direct” routings from air traffic controllers. While this can help shorten the route, the aircraft has already been fueled for the longer route and must still carry that extra fuel to destination.

2.4.    By working with the Civil Aviation Authorities (CAA), Air Navigation Service Providers (ANSPs) and Airlines, NACC, and SAM ICAO offices, and with the support of CANSO (CADENA) and IATA, it has been possible to facilitate the development of optimized city-pair user preferred routes that can be used by dispatchers for filing flight plans so that fuel savings and CO2 reductions can be achieved.

2.5.    On AIC-3 page below contains routes that may be used by aircraft operators in the preparation of optimized IFR Flight Plans (FPL) between origin and destination airports.

2.6.    As additional user preferred routes opportunities are identified and developed by ICAO NACC Airspace Optimization Task Force, the ICAO SAM Airspace Study and Implementation Group (GESEA), CANSO (CADENA), and IATA, and approved for use by the CAAs and ANSPs, this AIC will be updated and published in accordance with the applicable Aeronautical Information Regulation And Control (AIRAC) dates.

 

 

 

3. ATM requirements

ATS surveillance systems and VHF communications in both directions are required for the application of UPR.                                                          UPR will not be applied in case of partial or total ATS contingency.

 

4. Aircraft Capabilities

In order to file and fly the optimized routes, the following minimum aircraft capabilities are required:
