The fake news media has been in a frenzy lately, feverishly reporting on how “airplane turbulence” has greatly increased, and the reason why is… you guessed it… Climate Change (with two capital “C’s”). Take a look at some of these headlines:

If you listen to the “experts” and the media, you’d think everything under the sun, both good and bad, was somehow connected to the elusive Climate Change. However, is that truly the case, or could the media and these so-called “experts” be whipping everyone up into a frenzy for no reason? Well, that wouldn’t be a big surprise, right? And it could be happening, because of a new airline “environmental policy” called OptimizedProfile Descent, or OPD.

So, what exactly is OPD?

PSU:

Optimized Profile Descent (OPD) is a descent profile that starts at Top of Descent and, to the extent possible, comprises idle power descents that minimize thrust required to remain on the vertical path. OPD flight procedures use the capabilities of the aircraft FMS to fly a continuous descent profile minimizing level-off segments, based on the actual performance of the aircraft under current flight conditions along a fixed lateral path. The termination point of an OPD may be on an arrival procedure such as a published Standard Arrival Route (STAR) or at a point in space that allows for radar vectoring.

OPDs are designed to allow use of aircraft automation and piloting techniques to maximize fuel efficiency and minimize environmental impact. Instead of using a typical step down arrival procedure, with an OPD the aircraft flies a constant descent profile with engines at idle power and minimal thrust requirements. This can conserve fuel, limit emissions, and reduce noise. For more details, see the discussion on Optimized Profile Descent Procedures in the next section.

Optimized Profile Descent Procedures

One environmental concern in and around airports is noise produced by aircraftby aircraft. The flight techniques utilized during an Optimized Profile Descent are not new. Pilots use minimum power and optimal glide angle techniques whenever possible to achieve fuel efficiency and quieter landings. OPDs take advantage of these techniques to improve upon standard landing procedures in two ways:

Aircraft fly at higher altitudes for longer periods of time reducing the amount of noise exposure on the ground.

An optimal descent profile requires less work from the aircraft’s engine, as a result the engine produces less noise. Non-OPD air traffic control procedures may require arriving aircraft to follow a step-down flight path to resolve conflicts with other operations. During a traditional step-down procedure an aircraft descends until it reaches a specified altitude and speed, it then levels off and flies at a constant speed. The aircraft may repeat this procedure multiple times before landing.

Using an Optimized Profile Descent, the step-down flight path can be eliminated when possible and, in doing so, an aircraft may not be required to level off once it begins its descent. This allows an aircraft to stay at higher altitudes for a longer period of time. In addition, it requires less work from the engine than traditional arrival procedures. (Extra work is needed for a descending aircraft to level off.)

And here’s where things get interesting and possibly very manipulative. According to the tweet thread, traditional descents allow pilots to quickly move through pockets of turbulence. On the other hand, the slow descent during OPD forces planes to spend more time in turbulence, which is likely why there’s actually more turbulence.

Could “new turbulence” just be another ruse, much like the narrative around “wildfires”? We’re constantly hearing how wildfires are a direct result of “Climate Change,” even as cases of arson keep cropping up. With this kind of mixed messaging, it’s getting tougher to fully trust the so-called “experts. It seems that “science” has also been weaponized by the radical left.
