Folks, this is a matter of perception. Is such an act necessary under normal arrival procedures? I will submit that it is not. It really doesn't matter if it is legal or not.
We never know who is hanging around a given airport. Why do something that can bring attention to ourselves? Notice I didn't say "negative" attention.
There are four factions involved. (Actually more if we wanted to take it farther) 1) Pilots 2) RV pilots 3) Non RV pilots 4) Non pilot public. We have heard recently from the AOPA forums that we (RV pilots) have established a less than positive reputation with non RV pilots. Right or wrong, deserved or not, it is there. I've heard it around our community.
The unknown is how the public views us. I'm sure they don't know the specifics of different aircraft, but they can view differences in behavior and procedures. As an example, I live at an air park. It is P19 in Chandler, AZ. Check it out on Google Earth. It is a very unusual air park in that it is very urban. We have large tract residential areas on 3 borders.
On one occasion, I was talking to one of these neighbors. He asked why, on occasion, do some airplanes look like they are landing but go down the runway "like a bat out of hell?" The question and the tone were clearly unfavorable.
Occasionally, a couple of our Glasair or Lancair owners will make make high speed passes. I'm not grouping them into plane category because I know the guys. Just mentioning the plane for the next comment. Point being that the Cessna 182's or Cherokee's don't do such passes.
Also, no need to pick nits on the altitude or the high G pull up. You know what he is describing. Both Glenn and I are medical helicopter pilots. We have done extensive autorotation training. Flare altitude is critical for survival. I will be willing to bet that we can accurately guess the altitude of an aircraft (AGL) below 200' within 10'. So in the original post, he mentions 100'. I could have been 90 or 110.' Again, don't get technical on the altitude.
In summary, in this time in history, we need to self evaluate our every action. If there is any doubt as to its appropriateness, DON'T DO IT.
