PPGS Lesson 8.1 | Airspace: Charts

Welcome back to Epic Flight Academy's Private Pilot Ground School! This video covers Airspace and how pilots should operate flying within different Airspaces.
This course is taught by Epic Flight Academy's own Mike Thompson. Mike Thompson is the author of "Telling Is Not Teaching", which promotes the idea that the “new school” of teaching that embraces electronic technology cannot sacrifice the “old school” of human relationships because the human brain stills learns in largely the same way that it has for millennia.

One Nautical Mile is a minute of Latitude not Longitude.

Noup. Latitude is the Angular Distance of a place on the Earth Planet expressed in degrees and minutes (Horizontal Angular Divisions) from the Equator 0-90 degrees north or South. Longitude: They are Vertical Angular Divisions running 180 degrees East and 180 degrees West. They were created using TIME in the absence of a Natural reference to follow… Remember that Longitude has a reference tool associated to calculate the vertical angular distance (west-east) based upon the time. That’s why we have the Prime Meridian “Greenwich”. It is the Longitude what used the time and not the Latitude. Of course both (Lat/Long) will be given in degrees and time. But 1 NM = 1 minute of Lat AND 1 minute of Longitude as well. However the length in 1 minute of Longitude decreases as you move away from the Equator to the Poles.

Well said! One nautical mile is also one minute of longitude at the equator. My apologies. The only reason I pointed it out is because in the video, Mike mentions one nautical mile as one minute of longitude, no matter where you are, which is not true. Timestamp 11:51. One nautical mile is generally classed as one minute of LAT no matter where you are AND one minute of longitude at the equator. Distance between lines of latitude are generally consistent, BUT distance between lines of longitude change depending on how far north or south you are.

Good morning Mr. “Mgrudjsk”, I completely understand the point of view of Mike and HE IS CORRECT! Allow me to explain it to you 🙂: Sometimes, it is hard to grasp some basic concepts because we see the things in 2D (the graphics or images), however to understand this, we have to see it in a 3D, specially with the concept Longitud because we are using the term “Meridian Arc Length” which is the length corresponding to 1 minute of LATITUDE at the equator. However that horizontal ARC circumference gets smaller and smaller as you get closer to the poles. Now, that Meridian ARC distance is not the same as the Latitude Distance because when calculating the speed in KNOTS in the LONGITUDE you use a curve line slightly different than a straight line used with respect to the LATITUDE. That’s why the term NM has to be applied only on Longitude and not in Latitude. P.D. There is nothing to apologize, we in Epic LOVE the questions and also encourage each one of you to ask as much as you can to deeply understand the reasons behind every concept that will make you a better Pilot! “I LOVE the WHY ??”.
