EGNOS how to obtain RNP APCH operational approval to LPV minima in Europe
European Geostationary Navigation Overlay Service (EGNOS) how to obtain RNP APCH operational approval to LPV minima in Europe
The document provides a set of simple guidelines for aircraft operators within the European Civil Aviation Conference (ECAC) area to facilitate their operational approval by their national authorities to perform Localizer Performance with Vertical guidance (LPV) operations. It has been prepared by European Satellite Services Provider S.A.S. (ESSP SAS) under its EGNOS Service Provision contract with the European Global Navigation Satellite Systems Agency (GSA) and supported by the European Business Aviation Association (EBAA).
What are LPV approaches?
Technically known as RNP Approach procedures down to LPV minima, LPVs were introduced within the PBN concept as new approach operations based on SBAS, a technology providing augmentation to GNSS systems like GPS. This type of approaches allows for ILS lookalike procedures down to a minimum as low as 200 ft without the need of any ground infrastructure installation. As of August 2015, there are over 200 LPV procedures published in Europe with plans for more than 400 by 2017 (see map below, available here).
In addition, an Implementing Rule has been published by EASA in 2015 to support the implementation of APV procedures. You can find more details on this rule and LPVs characteristics and main benefits in Section 2.
Do I need a specific approval to fly them?
If you hold an AOC the answer is yes. If you are an NCC/NCO, then it depends on the specific regulations set by your NSA. Some States require general aviation IR pilots to at least undertake a specific training while others don’t have any requirement at all (see Section 8 for more details). Today, European CAT operators need to apply for a specific approval (SPA) to their competent authority. This is due to the fact that LPVs are a relatively new concept which require not only the that the aircraft and its navigation avionics have the corresponding airworthiness approval but also that pilots have appropriate training and checking standards and operational procedures in place.
Is the regulation expected to change?
Yes, fortunately, LPVs and other PBN specifications will be soon considered as standard practices becoming part of the IR license of pilots and standard operators’ procedures by default. These changes are currently reflected in EASA Opinion 03/2015 which has been addressed to the EC to amend the corresponding Commission Regulations by August 2016. These changes will eliminate the burden to apply for an SPA but operators will still be required to put the necessary operational procedures in place and accordingly amend their operational manuals to obtain the approval from their authorities, as it happens nowadays with other instrument approach procedures. Section 9 provides more insight to the upcoming changes to regulation.
