Assessing vertical flight profiles during climb and descent in the US and Europe: US/Europe comparison studies

摘要

□ Methodology validated □ Less level flight during climb □ Less level flight in Europe than in the US (2017) Region Descent Climb Europe 14.2 NM 3.2 NM US 28.2 NM 4.7 NM □ Level flight trends (2016 vs. 2017) □ Europe: Relatively stable □ US: Reduction of level flight during descent.
