This survey is related to the future of Aeronautical Charts for the Next Intended User.

As next intended user is to be understood an entity that receives the aeronautical data or information from the aeronautical information service (Annex 15 definition).
Among next intended users can be airlines, data houses, GA, ATS, RPAS operator, simulator operators, dispatch and others.

Military Organisations, which follow Annex 4, might also be interested to participate in the survey.

VISION: Establish the future digital aeronautical chart provisions that meet the needs of performance-based communication, navigation and surveillance and data set visualisation.
The implementation of System Wide Information Management (SWIM) online platforms require a quality-assured aeronautical data process from data origination, through instrument flight procedure design, to the creation of aeronautical data sets, through to provision of digital aeronautical charts or data sets to the next intended users.
To fulfil this vision, aeronautical charting must now keep up with Annex 15 Ed. 16 and PANS-AIM Ed. 1.

The role that charting will have in this system-wide and information management approach needs to be determined. It has to be decided what the main functions of the future aeronautical charts should be and who would be their main users. A question that also needs to be answered is whether some charts can be replaced by data sets.
ICAO Annex 4 was published during a time when aeronautical charts were created by manual methods and were used as a source of air navigation by airspace users.

Current aeronautical charts are “static views” designed for human interpretation. In an age where aircraft performance is increasingly dependent upon digital data and information, the actual functions and needs for the aeronautical charts in Annex 4 and Doc 8697 (Aeronautical Chart Manual) need to be revisited. Data or data sets rather represent the future for data/information provision for some of the information while digital or electronic charts will replace the need for paper charts.

Moreover, many aeronautical chart types are out of date and no longer produced by some States and also different types of chart users with new requirements exist, which are not even accounted for in Annex 4 or the Aeronautical Chart Manual.

As part of the next steps to reach the vision the following are to be addressed:

Rationalise the chart types in Annex 4;

Further promote and better explain electronic/digital charts;

Define the relationships between data sets and digital charts;

Adapt to future distribution channels (online distribution services e.g. SWIM);

Determine the need for production of each chart;

Acknowledge relevant charts types as per their use;

Adapt chart requirements to the digital world (symbolisation, elements, data sources, etc).
One of the first steps is to analyse what are the current users' requirements and expectations of charts. The analysis will commence with a questionnaire addressed to the next intended users (aircraft operators, pilots, data houses etc.) and Civil Aviation Authorities and Air Navigation Service Providers focusing on determining which charts are still being published and used and determining whether there is a need to continue having charts when aeronautical data sets with the same data content exist or could be made available.
