INTRODUCTION

• NATS is licensed to carry out the AIS function on
  behalf of the UK CAA.
• INTEGRATED AERONAUTICAL INFORMATION PACKAGE
  (IAIP) of which NOTAM is just one element
• Satisfy International requirements for the
  exchange of aeronautical information of a lasting
  character essential to air navigation (ICAO Annex
  15 SARPS)
• An AIS shall ensure that aeronautical information
  is made available in a form suitable for all
  those involved in flights ops, flight crews,
  flight planning, simulators, air traffic units -
  UK overseas

TRADITIONAL NOTAM

• AIS information (not just NOTAM) is disseminated
  by the International community. The structure and
  content must conform to specific standards.
• TODAY The whole community is still using NOTAM
  based on a system created 60 years ago, using
  loosely constructed free text messages. Primarily
  used for delivery over AFTN.
• There are some NOTAM that cannot be graphically
  portrayed at all ! e.g. FIR, Communications,
  AIS, Triggers, ATCC, ACFT Entry requirements.

THE WAY FORWARD Machine readable NOTAM

• Reliance on Automation, brings demands for high
  quality Information Data
• XNOTAM - a radical change. Data set in structured
  format, fully interpreted by automated system.
• GEO REFERENCED
• TEMPORAL
• LINKED TO STATIC DATA
• QUERY ENABLED
• BACKWARD COMPATIBLE

X NOTAM - THE BENEFITS

• Improved pre-flight briefing
• Increased efficiency
• Consistent quality
• Machine Readable NOTAM
• Note Not just a European project

IMPLEMENTATION

• To implement XNOTAM, a comprehensive computer
  model for aeronautical information is needed.
• EUROCONTROL - Second XNOTAM trial Autumn 2008
• Working toward operational implementation,
  proposed to start by 2010
• NATS is currently on a development path to
  implement AIXM model which will provide XNOTAM
  capability
