Safety and Performance Requirements (SPR) for Aeronautical Information
Services (AIS) and Meteorological (MET) Data Link Services
Description / Abstract:
This document specifies minimal baseline operational Safety and
Performance Requirements (SPR) for the data link delivery of AIS
and MET information as the primary means of communications between
air and ground. The aim of the AIS and MET data link services is to
provide aeronautical and meteorological information for flight
efficiency and/or hazard avoidance in all flight environments. Four
AIS/MET data link services are covered in this SPR: an aeronautical
update service that provides current updates of aeronautical
information; and three weather decision services that provide
current updates of meteorological information designed to support
flight crew decisions in three time categories (planning, near term
and immediate decisions). The document is based on a notional
architecture and is not intended for implementation and operational
use until validation activities are completed. It provides a
framework and a methodology to be used as the basis for assessing
implementation of new data link systems or architectures as
candidates for AIS and/or MET data link services.
