Having said all that, there is an ILS 02, if you follow the track 200 after departure off 20, maintaining a 3deg climb gradient minimum to MSA 3100ft (approx 10 miles) then left turn to Rogag in uncontrolled airspace, then you would I believe fulfill any obstacle issues in that direction.
The left turns at 0.5 and 2.5nm are mainly for Noise Abatement around Bawtry.
