What is the primary purpose of the En Route Flight Advisory Service (EFAS)?

The primary purpose of the En Route Flight Advisory Service (EFAS) is to offer weather information and advice along flight routes. EFAS, also known as Flight Watch, is specifically designed to provide pilots with timely and relevant weather updates, which are crucial for maintaining flight safety and efficiency during en route operations. By receiving continuous weather advisories, pilots can make informed decisions regarding their flight paths, particularly when facing changing weather conditions or turbulence. This service enhances situational awareness and helps pilots navigate safely through potentially hazardous weather phenomena.

The focus of EFAS on weather information distinguishes it from other services. For instance, while navigation assistance is important, it is not the primary function of EFAS. Additionally, pilot training resources are not within the scope of the service, nor is it solely dedicated to handling in-flight emergencies, which typically fall under the jurisdiction of air traffic control and emergency services.
