Ray,
At an un-towered private airport its always up to the pilot to make the determination for the safest approach to land. When you have trees and wind something occurs called "rotors" where you get tumbling air turbulence coming off the trees. Rotors can really throw an aircraft around. It may be that this pilot needs to approach a certain direction to avoid rotors or it may be a certain approach offers better visibility or a better glide slope towards the field.
Regardless of the reason, the pilot in command is in charge and no FAA person standing on the ground is going to second guess the pilot's decision.
You're only hearing one half of the story here and obviously the person making the post is going to make himself seem like the good guy who did nothing wrong and was merely a victim. Yet, the poster admits that he made the FAA person "testy" so we know that there is more to the dynamics of the story than the side we hear.
If he gets lawyers involved or the FAA or the courts involved all of the above are going to recommend the same solution -- work out a compromise among themselves if they can.
A smart person would go have another discussion with the pilot now and try and work out a compromise. Talking costs nothing other than a little bit of time.
A dumb person would spend lots and lots of money only to be told in the end to work out a compromise. That or do something really stupid like some people here suggested and try to block the pilot's approach which could result in an injury or fatality and then get yourself sued for being exceptionally stupid.
I'm going to watch with interest how the rest of the story unfolds.
FYI: I have been flying since 1976, and fly regularly out of a small airport surrounded by trees. It has without question the worst turbulence in the area.
For this pilot to make significant noise on landing, he is probably dragging it in.
Turbulence on an approach can require additional speed, but that does
not require it to be a powered approach. Simply by the pilot doing a power off landing, or even a low power landing, the problem here goes away.
All our students are required to be able to do a short field, power off landing, over an obstacle, with the turbulence. It's not that hard, but many are never taught how to do it.
No matter what the situation here, there are options to abate noise during landing. i.e. bigger pattern, smaller pattern, steeper approach, power off.
AGAIN, the question is, why aren't any of these options not being used?
