How is EAD protected from hacking?

A multi-layered security system is in place, implementing the following services:

  • Firewall;
  • Virtual Private Network;
  • Intrusion Detection System;
  • Secure Transaction Recorder; and
  • Public Key Infrastructure with state-of-the-art COTS products as mitigation measures against potential security threats.
How often is EAD’s data updated?

The data is updated in real-time as information comes in from data providers.

I can not access VFR information (e.g. charts and circuit/AD regulations) in PAMS. Why can’t I access this information?

In the scope of EAD, participating states have committed themselves to provide the Aeronautical Information Publication in the format of the ICAO recommendations. The primary objective of these publications is to support international flight operation, which is mainly IFR.
It is possible to publish other products like VFR handbooks, etc. via EAD. However, each individual state decides whether or not to publish VFR handbooks via EAD.

If I have EAD, do I still need other AIS sources?

Only if you need AIP from non-ECAC states or a complete set of static data that are not yet available in EAD.

Is EAD an AIS for Europe?

No. EAD is not meant to be an AIS for Europe. EAD is a reference database of quality-assured aeronautical information. The data is provided by the migrated ECAC member states. Its quality and coherence is checked by EAD, which stores it and makes it available to the users. Member states remain responsible for the origination and publication of their own aeronautical information.

What are the benefits of EAD? Why should I use EAD?

EAD offers a number of clear advantages. They include:

  • a reliable reference source of European aeronautical information in real-time;
  • significantly improved data quality enabled by constant data-checking and based on ICAO and EUROCONTROL recommendations, including NOTAM validation and cross-border data-coherence verification;
  • a secure channel/vehicle for timely and efficient electronic distribution of aeronautical information to all users; and
  • reduced costs – via elimination of investments in development and maintenance of systems by both Aeronautical Information Services and end-users, as well as in decreased time spent in distributing and receiving information.

Why should I use EAD?

  • EAD is a one-stop shop: one click of the mouse and you have access to up-to-date, quality-assured aeronautical information.
  • EAD data can be plugged straight into the software suites that you already use, so there is no need to learn how to operate a new system. 
  • Everyone has access to the same data at all times, making route planning and forecasting easier, safer and much more efficient. 
  • Pilots can check up on their planned routes, online, from their homes or hotels.
What cost savings can I expect from using EAD?
  • Data providers no longer have to waste resources on manual checking and correction of each others’ data.
  • Data users have access to a cost-effective, single source of validated data to cover most, if not all, of their AIS needs.
  • Data providers and data users no longer have to invest in the development and maintenance of their own aeronautical information data processing systems.
What data does EAD offer?

The European AIS Database offers all users the following types of data:

  • Original & processed messages international NOTAM covering worldwide (including ECAC).
  • Worldwide static data used for NOTAM validation and PIB generation.
  • For the ECAC area, EAD includes the AIP, Amdt and Supplements, AIC and Charts as well as the complete set of static data contained in the state’s AIP.

All the above mentioned data – except the complete set of static data – have been available via EAD since it started operations. The complete set of static data contained in the EAD AIPs is being completed, with more being added as various ECAC member states migrate fully to EAD. The database will reach maximum effectiveness by the end of 2006, when all ECAC-based data providers will have successfully migrated.

What happens if the EAD server crashes?

EAD provides a helpdesk 24 hours a day, seven days a week. In the event of hardware and/or software failures, a helpdesk member is immediately available to solve the problem. Moreover, a backup site, which is located ten kilometres away from the primary site, will take over in case of loss of connection at the primary site.

What tools do I need, and how much does it cost?

For airlines and data providers, EAD data is FREE OF CHARGE! This is possible because EAD is a EUROCONTROL service. That means its cost is covered by the Agency’s budget.
If you are not an airline or a data provider, you will have to pay to access EAD Pro and My EAD data.
Either way, to access and manipulate the data, you will need hardware, software and communications links. These are your own responsibility. From easiest to most complexes, your options are:

EAD Basic
This is free of charge. All you need is a web browser and an Internet connection. EAD Basic offers simple access to current, effective data.

This application suite offers more advanced facilities, notably the ability to create and modify profiles, charts, routes and document libraries. Your EAD Pro terminal is connected directly to the EAD database through a secured network and provides access to all EAD operational applications and services via a user-friendly graphical interface. Installing EAD Pro is easy: the only hardware requirements are a PC connected to the Internet or the EAD Wide Area Network. EAD Pro is a modular service, offering various combinations of applications depending on your needs. For a cost estimate of the various modules, please contact us.

Clients who manipulate AIS data using their own applications may wish to access the database directly via My EAD. My EAD offers a standard interface (the “EAD System Interface“) that lets clients exchange information directly with EAD’s data centres. Since My EAD must be tailored to fit your existing IT systems, there are development costs associated. To receive an estimate of these costs, please contact us.

Where does EAD’s data come from?

Migrated states directly enter and maintain their static data – and create their NOTAM – in EAD. Eventually, all 41 ECAC (European Civil Aviation Conference) states that are responsible for providing Aeronautical Information Services (AIS) will be migrated. These services are provided by civil and military, state-owned or privatised Air Navigation Service Provider (ANSP) organisations. Currently EUROCONTROL is maintaining the minimum static data and AIP for the non-migrated states and is processing the worldwide NOTAM.

Who runs EAD?

EUROCONTROL owns and manages the EAD service. EUROCONTROL is also responsible for the continuous enhancement of EAD. The provision of EAD service is provided by a private company on behalf on EUROCONTROL.
