Dash 7s at EGLL
Hi,
On the subject of early turns:
I seem to recall that during the fairly brief period that British Midland operated DHC 7s out of EGLL they would routinely turn left in the climb somewhere over the mid-point of 27L ! (probably 28L at the time) and climb out over the Cargo area; I can only assume by special arrangement.
Interestingly, the Brymon guys did not tend to do the same thing.
