The weather was challenging, but quite flyable, until just before the JOT VOR, which was the outer marker on the ILS2L approach. The ATIS called out the overcast at 800 AGL, the minimum I needed (mistake #5not mine, but it counted anyway.) Chicago vectored me quite quickly, recognizing my icing potential, and I came in at 400 AGL.

VOR (Very High Frequency Omnidirectional Range) stations were once the most common radio navigational aid (NAVAID) in the United States. Since 2016, the FAA has been decommissioning VORs as GPS becomes the primary form of navigation. The FAA added two new expanded SSVs for Low and High VORs. What is a Service Volume?

A temporary flight restriction (TFR) may be issued for: Areas around major sporting events below 3,000 AGL and within 3 nautical miles. VOR/DME must complete an online course covering flight operations in the D.C. Areas visited or traveled by the President, Vice President, and other public figures. Both are correct.

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. It consists of two independent components VOR and TACAN.

VFR to MVFR…then 2 miles visibility and a ceiling of 1,200 feet agl. Next, introduce the VOR. Have them use the VOR to determine what radial they are on, and if the unit has DME, show you where they are on a sectional. These flights work best if they are limited to an airport 10 to 15 miles away. What could go wrong?

It typically begins at 1200 feet AGL but can start lower in some locations. The 1200-Foot Rule Usually, Class E airspace starts at 1200 feet Above Ground Level (AGL). The 700-Foot Exception In some cases, Class E can begin as low as 700 feet AGL to offer support for instrument approaches. This is the most common configuration.

Before RNAV, pilots had to rely on radios (NAVAIDs) and antennas on the ground such as VORs (Very High-Frequency Omnidirectional Range) and NDBs (Non-Directional Beacons). Theyre pretty much the same thing, but heres the difference: DH is measured above the ground (AGL). DA is measured above sea level (MSL).
