Long Trips & Small Airplanes

Plane and Pilot

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.

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.

Riding the Mountain Waves

Plane and Pilot

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.

Drone Lingo Simplified: Acronyms Every Pilot Needs To Know

Pilot Institute

AGL Above Ground Level AGL is simply a way to tell the basis from which any given height or altitude is measured. Simply put, 400 feet AGL means that the 400 feet is measured from the underlying ground surface above the specific airspace. This is as opposed to other altitude measurements, such as AMSL or above mean sea level.

FAA Updates Datalink Weather Advisory Circular

iPad Pilot News

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).

What Is a SPECI and When Is It Issued?

Pilot Institute

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.
