on this episode of the free pilot training channel we're going to be discussing the different types of airspace this is a really important subject for pilots to learn because we need to know the different rules weather minimums and equipment requirements for each type of airspace we have different types of air space to keep aircraft separated and to keep us from hitting each other there are four basic types of airspace controlled uncontrolled special use and other in this lesson we're going to focus on controlled and uncontrolled airspace but we are going to discuss those other two in a future lesson so be sure and subscribe and hit the bell notification so you don't miss out on that let's take a look at the six classes of airspace you need to be familiar with we've got alpha bravo charlie delta echo and golf by the way unless you've already done so you will need to memorize the phonetic alphabet don't worry about the numbers or the morse code there but try to memorize this as soon as possible like i said we have six classes but we have two types controlled and uncontrolled classes a through e are controlled airspace this means we can receive radar services from atc and if we're receiving those services we're under radar control now we will use these services too but is specifically designed to keep people who are flying on instruments safe class g airspace is uncontrolled airspace you can remember this by thinking g for government free aircraft and clash to your space are typically not under radar control now let's take a quick look at each one of these first let's take a look at class alpha airspace that's this red area here we're not going to spend too much time talking about this one because you need to be on an ifr clearance to be up here among other things but you do need to know that class alpha airspace goes from 1 8 000 msl to flight level six zero zero that's a pressure altitude of sixty thousand feet by the way you heard me correctly this is one eight thousand not eighteen thousand from now on when it comes to altitudes of ten thousand feet and above we need to enunciate them this way for example instead of ten thousand we should say one zero thousand this is one one thousand one two thousand one three thousand and so on we don't ever want there to be confusion at which altitude atc wants us at if you're wanting a good way to remember class a airspace remember a is for above this airspace is above where we can go as vfr pilots now let's take a look at class bravo airspace which here is depicted as this yellow upside down wedding cake class bravo airspace is really busy airspace you'll see this around really big airports like dallas fort worth and chicago o'hare a good way to remember this is that b stands for busy class bravo airspace starts at the surface and typically goes up to 10 000 feet agl in the next lesson we're going to really dive into the details on class bravo airspace but for now just remember that we need to be specifically cleared by atc to go in there class charlie airspace is crowded but not as busy as class bravo it's also shaped like an upside down wedding cake it is smaller though and that upper level is typically only 10 miles in diameter this airspace starts at the surface and goes up to 4000 feet agl remember c is for crowded and we also have to communicate with atc before we can go in here next up we have delta airspace typically class delta airspace is shaped like a cylinder it's usually five miles in diameter and it surrounds smaller towered airfields this airspace starts at the surface and goes up to 2500 feet agl the d here stands for dialogue because we need to talk to their tower before we can go in their airspace next let's look at class echo airspace you can remember this airspace by thinking e is for everywhere else that's because class echo airspace is controlled airspace that's not designated as alpha bravo charlie or delta most of the time echo starts at 1200 agl and goes up to the bottom of class alpha sometimes in busier areas echo will start at 700 agl though probably the biggest thing new pilots forget is that class echo is controlled airspace just remember we can get radar services here so that makes a controlled airspace the last type of airspace we're going to look at today is class golf as i already mentioned g is for government free because this is uncontrolled airspace also remember g is for ground because typically you see class golf up against the surface basically class golf is everything that's not alpha bravo charlie delta or echo and it's the least restrictive of all the airspace classes i hope you guys got some really good training today please hit that like button for me and i'll see you in the next episode
