This week Bombardier sent their CS100 to London City Airport for certification testing. This airport has unique requirements because of a steep glideslope going into the airport. Based out of Stansted for tests, Bombardier took their aircraft in and out of LCY. Despite taking a range hit using LCY, the CS100 will have the best range for a commercial airliner from that airport.
Here is a video of the second landing at LCY. Note how quiet it is. Clearly a “good neighbor” for people living near the airport.
