AIM 5-3-3 ) Change in the average true airspeed (at cruising altitude) when it varies by 5 percent or 10 knots (whichever is greater) from that filed in the flight plan. ( Each is defined by varying ceilings and visibility. IFR = Ceilings between 500’ and 999’ AGL and/or visibility between 1 and 3 miles.

Often, turbulence is the harbinger of mountain waves, not the ideal ceiling—and visibility unlimited—day. FAA weather charts can help for higher altitudes but when just a few thousand feet agl, they may be less useful. Eighty-knot tailwinds aloft and higher-than-normal temperature difference between the surface and aloft.

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.

The AC states limited coverage below 5,000′ AGL, but in our experience you should start getting reception within 1,000′ AGL in all but the most remote or mountainous regions. For example, ground-based systems that require a line of sight may have relatively limited coverage below 5,000 feet above ground level (AGL).

Cloud ceilings below 1,500 feet or cumulonimbus clouds can trigger a SPECI. A sudden wind shift, a 10-knot or greater speed increase, a 45-degree or more direction change, or gusts exceeding limits may also cause a SPECI. This includes the wind direction in degrees and the wind speed in knots.

VFR to MVFR…then 2 miles visibility and a ceiling of 1,200 feet agl. It might be no greater than 6 knots with gusts to 10 mph. Then the CFI should increase the winds so they are 10 knots (or more) above the demonstrated crosswind component. It’s just a few minutes, right? What could go wrong?

This central core extends up to around 10,000 feet MSL, the airspace’s ceiling. However, the ceiling for each shelf is the same as the core. Although Class B airspace has a typical ceiling of 10,000 feet MSL, exceptions exist. New York’s Class B airspace has a 7,000-foot ceiling, allowing more room for overflying aircraft.
