More precise management of arrival patterns surrounding an airport can have a big impact on the noise footprint. This solution introduces a new concept of operations that increases the glide slope to a second runway aiming point (IGS-to-SRAP) to reduce the amount of noise at ground level, as well as fuel burn and CO2 emissions. The solution can also improve time efficiency peak and non-peak periods where the optimised wake separations can help optimise flight profiles and the airport layout allows a reduction in runway occupancy time and taxi-in time for aircraft using the SRAP.

. The new enhanced arrival procedure (EAP) improves performance by using two active thresholds on a single runway and an increased glide slope to the second one, and may make use of satellite navigation and augmentation capabilities, such as Ground-Based Augmentation System (GBAS) and Satellite-Based Augmentation System (SBAS).

The procedure applies an increased glide slope, above the standard approach angle for the existing runway threshold and up to 4.49°, to an aiming point further down the runway threshold. The published procedure enables inbound aircraft to reduce noise footprint and possibly reduce runway occupancy time and/or taxi-in time depending on local runway/taxiway layout. Unlike the increased glide slope concept (which applies to the runway physical threshold), increasing the glide slope on an additional (second) runway aiming point should prevent a potential reduction of airport capacity and may increase capacity through optimised wake turbulence separations.

The solution also offers additional benefits over the second runway aiming point concept (SRAP), where the slope angle remains unchanged. IGS-to-SRAP enables a further reduction of noise impact and wake turbulence separations for an equivalent displacement of the additional runway aiming point.
