[KLMO]: Shifting the Model

Citizens for Quiet Skies, in Longmont, CO, has fought heroically to bring balance and moderation to the skydiving noise impact by Mile Hi, at Vance Brand Airport [KLMO]. The group took their concerns to the state courts, and then took it further to an appeal. In the process, CFQS has helped to illuminate yet one more reason that aviation impacts are out of control: the court systems (just like the faux-regulators) are biased towards accommodating commerce, and too quick to defer to FAA and federal authority.

I ran into this quote by R. Buckminster Fuller:

“You never change the existing reality by fighting it. Instead, create a new model that makes the old one obsolete.”

He makes a good point. When you study aviation impacts, you see ample evidence that, no matter where it is (a skydiving issue in exurbia, an air tour issue at Grand Canyon, a NextGen impact near a major hub airport, and so forth), the present imbalance is carefully sustained – and even expanded – via the carefully coordinated use of propaganda tools. The Av-Gov Complex uses propaganda tools to frame the issues favorably for air commerce while also keeping the average person from seeing the relevant truths.

Led by lobbyists and with ample faux-regulatory cover provided by FAA, the Av-Gov Complex created the present model, and they are being damned careful to control any efforts to change that model. But, facts and truths are problematic to those who are corrupt and self-serving; if we persist, as Kim and others have in Longmont, eventually we can shift the model and restore the balance. The noise impacts are real and problematic, just as the aviation operator profits are real and narrowly focused; but we can change the model to include other important factors, such as safety.

Shifting the Model to include SAFETY

One relevant truth about skydiving is this: skydive operators consciously choose to offset their climbs, so that the noise impact is not happening over the actual airport but instead is happening many miles from the airport. This decision shifts the noise impact onto people who may have no idea why, starting on a certain sunny day a few years ago, they now always hear lots of droning airplanes diminishing the best weather-days of the year.

There are safety consequences of this decision that are often overlooked. In particular, a skydiving plane doing repetitive climbs far from the airport drop zone poses a higher midair-collision hazard to other small planes passing through the airspace.

In the Longmont example, FAA’s aeronautical charts include a symbol at KLMO to alert pilots that this is a skydiving airport … but, if the climbs are far from the airport, even the most safety-conscious pilot, passing through may not see the skydive plane until it is too late. And the edge of the Front Range is a heavily-flown airspace for small planes.

A proactive FAA would judiciously constrain the skydive operator on where they must conduct their climbs, flying within a clearly charted climb zone positioned over and adjacent to the charted drop zone. For example, they might require climbs within a 2-mile radius of the airport center, or the drop zone coordinates. If the weather was marginal within that defined climb zone, the operator would simply have to stay on the ground, which eliminates both safety risks and noise impacts. If the repetitive noise generated within the defined climb zone increases noise complaints to those near the airport and under that airspace, then FAA would have the hard data they need to further constrain the operator’s annual permit letter, imposing hour-limits per day, alternate days off, and other noise mitigation strategies.
