787 take-off performance
I live a few miles north of Gatwick so I see aircraft after they have taken off and turned 180* to the north.
I've long thought that 787s appear to be very low. I've recently taken up cycling and passing the end of the runway, it looks as if 787s clear the trees outside the airport's fence only by a wingspan. I've observed two (TUI and DY) whose main wheels left the runway 7 & 9 seconds before flying over the end of it; and on FR24 I've noted a 787 at 1000' where the preceding Airbuses were at 2000'.
Surely they can be more sprightly than this - what advantage is there in trimming performance so much more than other aircraft do?
I'm sure I'm entirely wrong, but it seems to me that an engine failure on such a slow take-off must be more hazardous than when both engines are already on full power, particularly when there are trees at the end of the runway.
