Class E airspace has four different floors depending on location - and missing them on your sectional can put you out of compliance without realizing it.
PatternLearn what the Maximum Elevation Figure (MEF) on a sectional chart really tells you and how to use it to avoid controlled flight into terrain.
PatternA TRSA isn't a class of airspace - it's voluntary radar service drawn in black on the sectional. Here's how to spot it and use it.
PatternLearn to read the blue Maximum Elevation Figure on sectional charts and use it to pick a safe, legal VFR cruise altitude.
PatternClass Bravo airspace requires a specific clearance to enter - learn the shape, the sectional numbers, and the three words that legally let you in.
PatternLearn how the Maximum Elevation Figure (MEF) on sectional charts keeps you safely above terrain and obstacles during VFR cross-country flights.
PatternLearn how to read the Maximum Elevation Figure on a sectional chart and turn it into a safe VFR cruising altitude.
PatternLearn how the Maximum Elevation Figure (MEF) on sectional charts sets a safe terrain floor for your cross-country cruising altitude.
PatternThe Maximum Elevation Figure is the little blue number in every sectional grid that guarantees terrain and obstacle clearance - here's how to use it.
PatternRadio Hangar explores Class Echo, the Magenta Fuzz and the Blue Fuzz, and Where Controlled Airspace Actually Starts Over Your Home Field.
PatternLearn what the Maximum Elevation Figure (MEF) on a sectional chart really means and how to use it to plan a safe cross-country cruise altitude.
PatternClass Echo is the airspace you fly in most yet understand least - here's how to decode the magenta and blue vignettes and its cloud rules.
PatternWhat the Maximum Elevation Figure (MEF) on a sectional chart means, how it's built, and how to turn it into a safe cruising altitude.
PatternLearn to read the sectional's Maximum Elevation Figure, apply FAR 91.159, and pick checkpoints you can actually spot from the air.
PatternDecode every hatched line on your sectional - Prohibited Areas, Restricted Areas, MOAs, Warning Areas, and TFRs - and know exactly which ones require permission to enter.
PatternClass E airspace covers most of the continental U.S., but its shifting floor - from the surface to 14,500 ft MSL - trips up students on written tests, oral exams, and real flights.
PatternThe floor of Class E airspace isn't a single altitude - understanding its multiple levels determines your legal weather minimums on every VFR flight.
PatternClass E airspace has a variable floor - 1,200 AGL, 700 AGL, or the surface - and where it begins determines which VFR weather minimums apply to your flight.
PatternLearn how to pick VFR cross-country checkpoints that are actually visible from cruise altitude instead of landmarks that disappear.
