Service to Aviation
Welcome to the Service to aviation service
Overview
A range of space weather phenomena can affect both aircrew and aviation technical infrastructures. The health of aircrews can be affected due to elevated radiation exposure mainly caused by Galactic Cosmic Rays (GCR) and by occasional solar eruptions of energetic charged particles (Solar Energetic Particles - SEP). Technical infrastructure can suffer from degradation or loss of communication and navigation signals, as well as avionics errors. Such disruptions can be caused by both electromagnetic and charged particle radiation, as well as changes in the ionospheric conditions.
The "Service to aviation" aims at provision of access to global information, data, models and tools addressing these issues to help pilots and airline dispatchers in flight planning, especially for flights affected by space weather effects.
This service is implemented through a combination of products, tools and alerts which can be found in the sections below along with expert support provided by the teams constituting the ESA Space Weather Service Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don’t hesitate to contact the Helpdesk.

User Manual
The radiation environment at aviation altitudes is shaped mainly by Galactic Cosmic Radiation (GCR) that comes from outside of our solar system, is modulated by solar wind, and interacts with Earth’s magnetosphere and atmosphere. As an effect, radiation exposure at aviation altitudes is slightly higher than that at ground level. Additionally, some solar events may lead to additional enhancements of radiation exposure not only in atmosphere but also even on the ground – so-called Ground Level Enhancements (GLEs). The elevated radiation at flight altitudes during a GLE, although temporal, can be notable especially for high latitude flights.
