  1. LECTURE 4:ICAO CHART requirements NAVIGATION

  2. INTRODUCTION • The world of aviation requires maps that are unlike those used in ground transportation. • For the safe performance or air operations: • Current, comprehensive and authoritative source of navigation information is available at all times. • Aeronautical charts provide convenient medium for supplying information in manageable and coordinated manner.

  3. INTRODUCTION • Aeronautical charts not only provide the two dimensional information but also portray three dimensional air traffic service system. • All charts produced by ICAO states make reference to them for: • Flight planning • Air traffic control • Navigation purposes.

  4. INTRODUCTION • The aeronautical charts must be standardized. • Without the global standardization of aeronautical charts it would be difficult for pilot and other chart users to effectively find and interpret important navigation information. • Thus, the safe and efficient flow of air traffic, navigation and flight planning are facilitated by aeronautical charts drawn to accepted ICAO Standards.

  5. ICAO - ANNEX 4 • Annex 4 contain The Standards, Recommended Practices and explanatory notes for Navigational Charts. • Annex 4 define the obligation of States to make available certain ICAO aeronautical chart types and specify: • Chart coverage • Chart format • Chart identification • Chart content (standardized symbol & color use)

  6. ICAO - ANNEX 4 • The goal is to satisfy the need for uniformity and consistency in aeronautical charts that contain appropriate information of a defined quality. • There are 21 types of ICAO aeronautical charts series. • All the types intended to serve specialized purposes such as: • Detailed charts for individual aerodromes/heliports. • Small scale charts for flight planning. • Electronic aeronautical charts for cockpit display.

  7. GENERAL CHARTS • Basically, there are three series of charts available for planning and visual navigation, each with a different scale which are: • Aeronautical Navigation Chart - ICAO Small Scale charts • World Aeronautical Chart - ICAO 1 : 1 000 000 charts. • Aeronautical Chart - ICAO 1:500 000 series

  8. GENERAL CHARTS • Aeronautical Navigation Chart - ICAO Small Scale charts basically: • cover the largest area for a given amount of paper • provide a general purpose chart series suitable for long-range flight planning

  9. GENERAL CHARTS • The World Aeronautical Chart - ICAO1 : 1 000 000 charts provide complete world coverage with uniform presentation of data at a constant scale, and are used in the production of other charts. • The characteristic of Aeronautical Chart - ICAO 1:500000 series are: • supplies more detail • Provides a suitable medium for pilot and navigation training. • Most suitable for use by low-speed, short- or medium-range aircraft operating at low and intermediate altitudes.

  10. Operational requirements for charts • For the purposes of this Annex, the total flight is divided into the following phases: • Phase 1 - Taxi from aircraft stand to take-off point • Phase 2 - Take-off and climb to en-route ATS route structure • Phase 3 - En-route ATS route structure • Phase 4 - Descent to approach • Phase 5 - Approach to land and missed approach • Phase 6 - Landing and taxi to aircraft stand.

  11. En-route Chart • Portrays the air traffic service system, radio navigation aids and other aeronautical information essential to en-route navigation under instrument flight rules. • Designed for easy handling in the crowded space of an aircraft flight deck. • The presentation of information is such that it can easily be read in varying conditions of natural and artificial light.

  13. Plotting Chart • Provides a means of maintaining a continuous flight record of aircraft position. • Sometimes produced to complement the more complex en-route charts. Figure: North Atlantic Plotting Chart

  14. The Area Chart • This chart shall provide the flight crew with information to facilitate the following phases of instrument flight: • the transition between the en-route phase and approach to an aerodrome; • the transition between take-off and en-route phase of flight. • Designed to enable pilots to comply with departure and arrival procedures and holding pattern procedures. • Co-ordinated with the information on the instrument approach charts.

  15. The Area Chart Aeronautical data • Aerodromes - All aerodromes which affect the terminal routings shall be shown. Where appropriate a runway pattern symbol shall be used. • Prohibited, restricted and danger areas shall be depicted with their identification and vertical limits. • Area minimum altitudes shall be shown. • Air traffic services system - The components of the established relevant air traffic services system shall be shown.

  16. Instrument Approach Chart • Provides the pilot with a graphic presentation of instrument approach procedures, and missed approach procedures to be followed should the crew be unable to carry out a landing. • This chart type contains a plan and profile view of the approach with full details of associated radio navigation aids and necessary aerodrome and topographical information.

  19. Aerodrome/Heliport Chart • The charts show: • aerodrome/heliport movement • visual indicator locations • taxiing guidance aids • aerodrome/heliport lighting • terminal buildings and aircraft/heliport stands • various reference points for checking navigation system • Operational information (strengths and radio communication facility frequencies). • Hangars

  20. Aerodrome/Heliport Chart • Provides an illustration of the aerodrome or heliport • Allows the pilot to recognize significant features, rapidly clear the runway or heliport touchdown area after landing and follow taxiing instructions. • At large aerodromes where all the aircraft taxiing and parking information cannot be clearly shown on the Aerodrome/Heliport Chart - ICAO, details are provided by the supplementary Aerodrome Ground Movement Chart - ICAO and the Aircraft Parking/Docking Chart - ICAO.

  22. Aerodrome Obstacle Charts • The heights of obstacles around airports are of critical importance to aircraft operations. • Information about these are given in detail on the Aerodrome Obstacle Charts - ICAO, Types A, B, and C. • Aerodrome obstacle charts show: • runways in plan and profile • take-off flight path areas • distances available for take-off run and accelerate-stop

  23. Aerodrome Obstacle Charts • These charts are intended to assist aircraft operators in making: • the complex take-off mass • distance and performance calculations required • including those covering emergency situations such as engine failure during takeoff.

  24. Electronic Aeronautical Chart Display • Provides basic requirements aimed at standardizing electronic aeronautical chart displays while not unduly limiting the development of this new cartographic technology.
