- Definição1
- The primary objective of EFAS (also known as flight watch) is to enhance aviation safety by providing enroute aircraft with timely and relevant weather advisories. This objective is met by providing complete and accurate information on weather as it exists along a route pertinent to a specific flight. The aim is not only to provide information in a timely manner so that unnecessary changes to a flight plan are not required, but also to provide the pilot with the opportunity to make a decision to terminate the flight or alter course before adverse conditions are encountered.
