Natural icing testing is a unique part of the test program required to certify aircraft to operate in all weathers. Over the last three years employees at the Bombardier Flight Center (BFTC) in Wichita, have conducted natural icing testing during the development and certification of two clean-sheet aircraft programs (C Series and Global 7500). This testing included four measured icing campaigns and 1 unmeasured campaign. This presentation will discuss the learnings gained from Bombardier's first two all axis Fly By Wire (FBW) aircraft, including the development of operational methodologies that combine institutional knowledge and new ideas. It will cover the changes in approach that longer range, larger cabin aircraft require in this test regime, and how the incorporation of FBW technology has changed the test approach from an overall certification point of view. It will also cover lessons learned on best practices to conduct testing in this challenging regime.
