Overview

Background & policy context:

In the worst visibility conditions, the operation of an ILS (Instrument Landing System) requires the utmost care to guarantee the safety of the provided service. This induces important air traffic capacity limitations. GIFT project has studied Ground Based Augmentation Systems (GBAS) configurations, considered as one of the more promising solutions to overcome ILS limitations.

Objectives:

The objectives of the GIFT project were the assessment of high level requirements and the conceptual design, simulation and evaluation of a combined GBAS/ABAS configuration for the achievement of CAT II/III landing operations.

Methodology:

For GBAS CAT I, all performance requirements have been defined by analogy with CATI ILS and agreed at ICAO level. For CAT III, GIFT has assessed that the derivation of the GBAS requirements using the same ILS-LOOK alike methodology as for CAT I, leads to a situation in which the performance can not be reached with sufficient availability, if a GPS L1 satellite navigation GBAS configuration is considered.
