This document recommends criteria and requirements for a Flight Management System (FMS) for transport aircraft. The FMS shall provide the functions of Lateral Navigation, Vertical Navigation, and Performance Management and may include Time of Arrival Control. The FMS design shall take Human Factors considerations into account to produce a fault tolerant system.
This annex recommends additional design objectives applicable when control laws or control characteristics are modified for the purpose of Flight Envelope Awareness/Protection. While only manually controlled flight is addressed, it is assumed that Autoflight, Autothrottle, or Autothrust performance is compatible.
This document specifies requirements for both an airborne Microwave Landing System (MLS) receiver and an MLS area navigation (MLS/RNAV) system. This equipment shall derive aircraft position and guidance for flight along precision three-dimensional paths within the MLS coverage.
This document specifies requirements for an Airborne Landing Guidance System (ALGS) electronic device. This equipment shall derive relative aircraft position and situation information for flight along precision three-dimensional paths within the appropriate coverage area. The precision three-dimensional path may be an ILS straight-in look-alike path or a complex, curved path. The requirements are applicable to electronic devices capable of receiving signals or other information from one or more sources, including but not limited to ILS, MLS, GNSS, or IRU inputs.
