The trees at the end of RWY24 don't look good on the aerodrome chart but they have been there since the start of operations by Easyjet and no problems have arisen so far.
No problems so far ? On the contrary there have been a number of fuel stops required by Easyjet flights when they have been unable to uplift the full fuel requirement for a direct flight with a heavy traffic load under certain ambient conditions. The common denominator is insufficient headwind on RW24 and too much tailwind on RW06 so that neither option will give the required RTOW.
The problem has been clearly identified as a RW24 second segment climb issue. There were ongoing discussions on this thread on this topic last year which included inputs from pilots actively involved in SEN operations. During this debate it became apparent there were plans to lop offending trees but there has been no news of actual developments.
The reference is not the Aerodrome Chart. It is the Type A Obstacle Clearance Chart.
