From the diagram it appears that the tower is located outside any take-off and approach areas specified in Casa regs.
If that is the case, then what hazard can it present if the pilots comply with the regulations and use sound airmanship?
From a quick look at Google Earth it appears that there is a town near the tower, playing fields, trees, power lines along the road near the threshold, so what extra hazard can a tower present?
I bet the people in the houses just to the north-east of the runway don't want you flying over there either.
Do you still fly Carl?
Which airport do you manage?
