MET: Minima Estimation Tool

MET: Minima Estimation Tool

Before committing resources to a full GNSS approach procedure design, stakeholders need to know what the expected descent minima will be. The MET estimates the likely height of these minima.

The Minima Estimator Tool is software providing an estimate of the operational minima that could be achieved using different types of approaches such as ILS approaches, and RNP APCH, including approaches to: 

  • LNAV minima
  • LPV minima (also called APV SBAS procedures, these are designed according to APV 1 or APV 2 criteria),
  • LNAV/VNAV minima (also called APV Baro).

It only addresses the straight-in final approach and the initial and intermediate (straight) missed approach segments.

The latest version (2.27 dated 9 June 2011) takes account of amendment 2 to the fifth edition of Doc 8168 Vol II.

Purpose

The aim of MET is to support Cost Benefit Analysis (CBA) or Benefit Assessments.

It is not intended to be used as a procedure design tool nor to replace existing commercial products although it may be useful during the planning (pre-design) and validation (post-design) phases.

MET is provided on the clear understanding that EUROCONTROL makes no warranty, whether express or implied, arising by law or otherwise, assumes no responsibility to any person or persons, and disclaims any liability with respect to the use of the software and any derivative works including but not limited to, any express or implied warranty of fitness for a particular purpose.
