An ATR 42 plane from ASECNA (Agence pour la sécurité de la navigation aérienne en Afrique et à Madagascar) has been equipped to navigate by receiving the signals from EGNOS. The plane will use EGNOS to steer a course along aviation routes over the major part of the African continent. Moreover the pilot will land using the EGNOS test bed signals called the Interregional Satellite Based Augmentation System (ISA) - available over the Africa-Indian ocean region - which is the EGNOS extension for Africa.
