The only 169 profile suitable to this stadium which factors obstacle clearance is the variable TDP helipad. The TDP is 115ft + the height of the obstacle in your takeoff path so I’d guess a minimum of 250-300ft. The single engine failure before TDP is a not an overly ‘dynamic’ manoeuvre unlike some types. You need good references through the chin window and you fly back down the same path with up to 192% TQ available.
