The only location within Bexar county that is not in a flight path is Government Canyon in Helotes.
It all comes down to one's own tolerance. I have many friends that live in the neighborhood and they could care less about the planes since the homes are well kept, the access street is very wide and has many walking paths, there is a multitude of mature trees that give amble shade during the hot summer months. Many of the residents are 'health conscience' and you can see them jogging off to Hardberger park which is directly adjacent to the location.
Another plus is that one is directly center between 410 and 1604 and when the Wurzbach parkway finally connects to 281, you can be anywhere in town in a flash. Most instances, one cannot hear the planes from inside the homes, so it is small compensation for all the benefits. Contact me if you have more questions on the area... i know it well.
Runway 12 Right is the main landing runway for San Antonio Airport during most aircraft traffic conditions subject to wind and weather.
Saying that, Churchill Estates is not directly under the glidepath to this runway but it is in a reasonable vacinity of the approach path.
What I would recommend is drive into Churchill Estates and sit there for a while to get a better idea of the noise issue. I was in the Air Force for 36 years, so to me, not an issue, for someone possibly considering a purchase in the area, highly recommend they check the area themselves or if not available have a friend or family member do so.
