The ATR 42 was specially equipped to receive and analyse EGNOS signal broadcast through the Inmarsat IOR–E satellite. It went through Niamey in Niger, Ndjamena in Tchad and Bangui in the Central African Republic before reaching Kenya, in Nairobi then Mombasa. The flight took more than 20 hours but then speed did not matter, the objective was to demonstrate a plane using EGNOS to ensure a safe trip.
