ATR performed well in 2019. We received 79 orders and delivered 68 aircraft for a book-to-bill of more than one. The turnover for the year was $1.6 billion and was boosted by a strong performance from our Services.
In 2020, the aviation industry is facing an unprecedented challenge that will last well beyond the current year. It is too early to understand the full impact on our backlog, however we have not had any cancellations to date.
Currently, 40% of ATR aircraft around the world continue to fly, playing a vital role in humanitarian missions and the transportation of essential goods to the remotest areas.
Naturally, during this time, ATR continues to support airlines 24/7.
Cargo is becoming increasingly important and we have developed a solution allowing airlines operating ATR aircraft to quickly and temporarily convert to a light freighter configuration, allowing them to unlock potential operations.
During this crisis, ATR is not standing still. While our major concern is always the safety and health of our employees and subcontractors, our manufacturing sites have never closed, and we have implemented a very strict health protocol that has allowed us to continue critical activities. We remain committed to the delivery of our new programmes, the ATR 72-600F freighter and the ATR 42-600 STOL. The first deliveries of our new cargo variant will happen this year.
ATR believes that regional aviation will resume its activities faster than international air traffic, because it will have a huge role to play in the recovery of the global economy, connecting communities around the world with necessary supplies.
