EUROCAE ED-36B PDF

PURPOSE AND SCOPE

The Minimum Operational Performance Specifications herein are designed to ensure that airborne receiving equipment approved as complying with them will be compatible with the ICAO Annex 10 Standards and Recommended Practices in respect of Microwave Landing System (MLS) including the November 2007 ICAO Navigation System Panel proposed MLS amendments. The minimum operational role for all receivers shall be that of Cat. I ILS replacement.

NOTE 1: It is anticipated that these proposed amendments will be published by ICAO in the Amendment 84 of ICAO Annex 10 in November 2009

Mandatory clauses are denoted by "shall".

Environmental test requirements have been specified in respect of the parameters which may be particularly susceptible to the effects of environment. Although this document provides a single minimum performance specification for receivers, several alternative environmental categories, as specified in EUROCAE ED-14D/RTCA DO- 160D may exist, those applicable to the conditions over which the equipment is declared to operate shall be applicable.

Demonstration of compliance with certain of the requirements of this specification may involve somewhat complex test procedures, e.g. where a scalloping of input signal is required. Suitable test procedures in respect of these requirements have been formulated and are included in Chapter 5. Alternative procedures providing equivalent integrity may be used.

The airborne antenna(s) coverage provided is assumed to be adequate for the operational requirements envisaged.

In this Specification, it is assumed that no multipath robustness is provided by the airborne antenna system.

This document provides minimum operational performance specifications for the airborne portion of the microwave landing system. Should the MLS functions be incorporated into multi-function equipment with other facilities, the requirements of this specification must be met whilst operating as an MLS receiver.

This minimum specification does not require the provision of guidance information decoded from the MLS ground back azimuth antenna. The receiver must be capable of providing all guidance and data information as specified in this document whether or not MLS back azimuth is provided in the ground installation.

Guidance contained in the following documents should be considered in conjunction with this specification:
