Ceiling Knot Turbulence 
Plane and Pilot
AUGUST 6, 2024
The route is simple, GPS direct, but…there’s my personal 1,000-foot en route ceiling requirement, and those silly Smoky Mountains. Also, from when I lived out West, there was the mountaintop clearance guideline—1,000 feet for every 10 knots of wind, with 30 knots meaning no-go. It was now time to plan the trip.

While most of it tends to be hidden away either in the cabin ceiling space or under the cabin floor panels, some of it – particularly the air conditioning riser ducts – is fitted in the cabin walls at certain intervals, making the inclusion of a window at that position impossible.

Often, turbulence is the harbinger of mountain waves, not the ideal ceiling—and visibility unlimited—day. We experienced moderate turbulence even at our gate. Eighty-knot tailwinds aloft and higher-than-normal temperature difference between the surface and aloft. I flew into that and the venturi effect that day.

Another interesting model is the 172RG Cutlass RG, which features retractable landing gear and a more powerful Lycoming O-360-F1A6 engine, offering a cruise speed of 140 knots. For instance, Knots 2U offers a Cessna 172 Cowl / Body Fairing Kit that improves aerodynamics and can increase cruise speed by 3-4 mph.

This had the effect of a rapid reduction of airspeed (to 80 knots) as the autopilot fought to maintain altitude. On the other side of the wave, the airspeed increased to 150 knots. I quickly disengaged the autopilot and reduced speed to maneuvering speed (118 knots) by pulling the throttle back. During the trip I put 18.1

These weather alerts each have their own role: AIRMETs warn about moderate conditions like turbulence, icing, and limited visibility, which can affect smaller or less equipped aircraft. SIGMETs alert pilots to more severe weather events like thunderstorms, volcanic ash, or strong turbulence that could pose serious risks to any flight.

Weather conditions on Groundhog Day were better than the week prior, characterized by a high ceiling and no thin screen of clouds hiding the ground from view. A target moved across my traffic display at 450 knots (518 miles per hour). "I Same course, same altitude, same frequency handoffs as the week prior. Photo by The Bear.
