AIP Supplement Belgium and Luxembourg 006/2025

1 Introduction

This AIP supplement describes the temporary changes to the RNP approaches at EBBR RWY 25R and RWY 25L in the context of HERON (High Efficiency Green Operations), a SESAR 3 JU Digital Sky Demonstrator.

The HERON project will evaluate the use of RNP approaches using Increased Second Glide Slopes (ISGS), i.e. approaches with a descent angle of 3.2° or 3.5° in addition to the standard angle of 3.0°. The overall scope of this project is to assess the environmental benefits of flying a steeper approach by reducing the environment footprint of aviation, in terms of:

Noise reduction;
CO2 emissions;
Fuel consumption;
Local environment quality improvements.

This supplement only describes the second period of ISGS RNP trials at respectively 3.2° to RWY25R and 3.5° to RWY25L.

2 Instrument Approach Procedures

2.1 General

The following instrument approach procedures of EBBR are temporarily withdrawn:

RNP RWY 25L
RNP RWY 25R

Temporary instrument approach procedures are installed as follows (see § 6 for details):

RNP A RWY 25L (descent angle 3.0°)
RNP C RWY 25L (descent angle 3.5°)
RNP A RWY 25R (descent angle 3.0°)
RNP B RWY 25R (descent angle 3.2°)

2.2 Availability

The temporary instrument approach procedures are available as follows:

RNP A RWY 25L
RNP A RWY 25R

Available H24 for all aircraft

RNP C RWY 25L
RNP B RWY 25R

Available only during the HERON trial period for aircraft operating under the ICAO designator of the following aircraft operating agencies:

European Air Transport (BCS)
Brussels Airlines (BEL)
TUI Fly Belgium (JAF)
Vueling (VLG)
and their subcontractors operating under the same call sign.

The HERON trial period will take place as announced via NOTAM.

Trials will only be scheduled in the off-peak hours: 2200-0500 (2100-0400).

Note 1: Prior to requesting these approaches, pilots shall verify that their aircraft is certified for the required PBN specification and that the navigational database is suitable and current.

Note 2: Capable aircraft of the participating airlines should use these procedures during the HERON trial periods, but may use ILS approaches instead if so required for operational reasons.

3 Information Dissemination

Start and end date for the overall trial period will be announced via NOTAM, with reference to this supplement. This does not mean that trials will actually take place on a given night, this depends on several factors (traffic demand, meteorology, etc.). If trials are in force at a given time, this will be clearly indicated in ATIS as “increase glide slope trials in progress”.

4 PAPI

The PAPI of RWY 25R remains calibrated for an approach angle of 3°. Aircraft using the instrument approach procedures RNP B RWY 25R shall therefore be aware that PAPI indications can be misleading.

On the right side of RWY25L opposite the existing PAPI, an additional PAPI is installed with the following characteristics:

VASIS

PAPI (Right/3.5°)
MEHT: 65 FT
Non-standard lamp colour: red/green instead of red/white
Activated during the trials and only between 2200 (2100) and 0500 (0400)

../graphics/eSUP/SUP_2025_006_Graphic1.pdf

Aircraft using the instrument approach procedures RNP A/ILS RWY25L during the trials shall note the following: TWO PAPI - DO NOT USE right hand PAPI at 3.5°.

5 Wake Turbulence

ATC will apply increased wake turbulence separation minima when an aircraft approaching with and angle of 3.5° is followed by an aircraft approaching with an angle of 3.0°. Extra speed limitations may be expected in order to maintain the increased wake turbulence separations.
