hey guys what's up John from flat Mike alpha comm and today we're gonna be
talking about Class G airspace so the good stuff the stuff that is
uncontrolled Class G airspace where it is how to identify it on the chart and
what are the altitudes associated with it where are you going to encounter it
so Class G airspace think about G in ground right Class G airspace is near
the ground it's going to be everywhere it is the default airspace because its
uncontrolled airspace everywhere touching the ground then you'll also
hear something that's a little bit outdated you'll hear that Class G
airspace goes from the surface on up to 14,500 feet MSL now this 14,500 foot MSL
value yes that's in the book yes that's a regulation in the far aim but it's not
really used anymore it's really been brought down with Class E airspace so
although you'll hear that number thrown around a lot and you'll hear on your
written exam Class G airspace goes up to 14,500 feet MSL yeah yeah yeah in
reality it doesn't it goes from the ground up to 1200 feet MSL and you're in
a stable where am I getting that information if we look at a sectional
chart any sectional chart we come over to the legend section you're going to
find in the legend where it says that these little lines here will
differentiate floors of Class E airspace that's greater than 700 feet above the
surface and it has a note here Class E airspace exists at 1200 feet AGL unless
otherwise designated as shown above with any of these markings here so classy
airspace always exists 1200 feet AGL on up okay so that's just going to be a
default we're gonna go ahead and use that being said if we're standing out by
this cell phone tower here Class G airspace is going to go from the surface
which is our default on up to 1200 feet AGL then it's Class E airspace above
that all right now if we come over here we have this magenta vignette this
denotes Class E airspace that is not starting at 1200 feet MSL or AGL rather
so if we look over here at our little legend here Class E airspace with a
floor 7 or feet above surface that laterally abuts Class G airspace great
so or Class E airspace with floor 700 feet above surface that
laterally buts 1200 foot or higher Class E airspace same exact thing they
have it twice but it really means the same thing here so when we look at
Venice Airport what we see is Class G airspace like
we've set out by the antenna from the surface on up to 1200 feet as we come in
here the Class G airspace is still touching the surface and even at Venice
Airport it's from the surface on up but it's going to stop at 700 that's what
this magenta vignette means so anytime you see this magenta vignette just think
of it stopping the Class G airspace at 700 feet and then it's gonna be class C
above that same thing down here we have Class E airspace from 7 feet on up Class
G below it touching the ground everywhere out in here Class G airspace
from the surface up to 1200 feet AGL there's no other airspace - noting that
it's different come to the middle of the state it's Class G airspace all the way
touching the ground but in this outline here the Class E starts at seven hundred
so the Class G airspace is only going from the surface up to seven hundred
feet AGL within this area inside of here now not to complicate the situation if
that's all you understand about Class G airspace you're in really good shape
you'll be just fine with these blue dashed lines out here
for bonus points if you want to know what they are its denoting Class G
airspace with the floor other than 14,500 feet MSL so when we see this
differentiates floors of Class E airspace
greater than 700 feet above the surface that's a complicated way of saying that
it's really Class G airspace is being allowed to come up so when we see these
blue dashed lines here what it's telling us it's Class G airspace like we said is
from the surface to 1200 all out here but as we come out here Class G airspace
goes from the surface up to 1300 feet MSL and then and that's all within here
so surface up to 1300 feet MSL and then out here
it's from the surface up to 2,700 feet MSL going on up now what's the purpose
behind that silly rules it's so far offshore you're not going to be falling
out there anyways this line here is about 12 miles offshore this little 8 is
line so you're not going going more than just a few miles offshore when you're
flying in the traffic pattern so this really won't matter too much
where you're gonna see things like this occur is way out west so way out west
here in the middle of nowhere we do have Class G airspace that goes up to nine
thousand feet msl mind you that's not a lot of class here space because you have
the surface is pretty high out there to the service is actually sixty seven
hundred and fifty eight feet out there and an even higher so although there are
a few areas where Class G airspace still goes higher than twelve hundred feet AGL
over the continental US it's really few and far between you gotta go way far out
west to find it where it's really not busy and the purpose of that is just to
give people uncontrolled airspace where they can hop into and go do silly things
so you're not gonna find it in the areas that you really fly in as a default all
I really want you to remember is that Class G airspace goes from the ground on
up to 1200 feet AGL unless you have this magenta ring that's it that's all there
is to Class G airspace real simple cut and dry just remember those things
you'll be fine so hopefully you guys found that helpful make sure you give us
