Hey guys! Jon from Fly8ma.com and today we're going to be talking
about how to use our E6B to find wind correction angles and ground speed based
upon our winds aloft and what sort of heading we found that we're going to be
flying off for sectional chart. So how fast we're going to go, how long it's
going to take us to get there, our fuel burn, all those sorts of things
could be derived from this. Make sure you have your E6B handy and you can follow along
with us. Go ahead and rewind or drag on back to replay anything you need to see
twice and work through it a couple times so it becomes cemented in your memory
and you'll be good go for your test. So we have our e6b here and what we
want to do with that is initially slide our little grommet down to 100 so we're
going to be right at 100 start there and we could start at any number but we want
to just start at a nice easy round number of 100 and then we can proceed up
for our wind. So we're going to use 250 at one eight for our winds
aloft. So we're going to dial this to 250 and then put a little dot
at 18 up from our starting point 18 up from our grommet so I'm going to use a
little piece of scotch tape there's a little dot on there. You could use a
sticky note or a dry erase marker or anything you really want. So I can also
go down to 90 and then just put my little dot at you know 18 up from there,
but just easier to start at 100 and then put my dot at 118. So my winds 250 at
18 knots or my winds aloft. Now my true heading on this I measured from my
sectional chart. My true heading for this trip today is going to be 080
080 and then I want to slide
my dot up to my ground or my true airspeed. My true airspeed I know is
going to be about 110 knots so slide that little dot to the 110 knot line
right there and then I'll read my ground speed to that grommet looks like
my ground speed is going to be about 128-129 knots and that little dot is slightly
to the right so looks I'm going to have to add about two degrees
This about two degrees we can see there's five there's ten so about adding
two degrees to 080 so I should fly a heading of 080
and then plus whatever my magnetic variation is for that area. Might be plus
an additional five degrees. So now we need a magnetic heading of 087
to actually have a ground track of 080 true and also my ground
speed will be slightly higher than my true airspeed. You can now go ahead and
calculate our estimated time and route for the trip, our fuel burn for our trip,
and we know exactly what heading we're gonna need to fly so we have all our
pertinent information. What we did to do it once more we started at 100, a nice round number,
our winds were to 250 at 18 so we dial up to 250 went to 18
there and then we went ahead and dialed in what our true course was going
to be that we drew on our sectional, which was 080. We slid this
on up to our true airspeed which was 110 based on our cruise performance charts
and everything like that. Kuras feet of 110 and we found we'd have
to turn two degrees to the right to actually have a proper ground track
about adding two degrees to 080 and then we read our ground speed
through that grommet to be about 129. Alright so now let's go ahead and work
through one more example problem here. Again, we're always going to start with
our grommet slid down to the 100 mark so we're down at 100 to start and then
we're going to say that our winds aloft oare 320 at 29 knots, so twist this
around to 320 and then go off 29 away from your grommet and put a little dot
so we're going to put our dot there at 129. Again we could have started off at
80 and then put a dot at 109 but it's just easier to start off at 100 and then
put your dot 29 up from that. So now we're going to twist around to our true
course we find a true course from the sectional chart from those true lines
and we found our true course to be 030 for our flight today.
So 0303 is our true course and our true airspeed that we calculated
from our cruise performance charts was 118 so we're going to move our little
dot on up there to 118
and we're going to read that our ground speed will be about 105 knots, so now we
can use our ground speed with our distance to find our estimated time and
route and our fuel burn. We could go over here and say that looks like oh we're
gonna have to turn minus 10 minus 12 minus 14 degrees off of our 030
heading so we're going to be on a 016 heading, but were around the
Venice Airport area Venice, Florida so we're going to add five four magnetic
variation which would then give us about a 021 heading so 021
magnetic 016 true heading to track a 030 true course over
the ground and again using the 100 and five knots ground speed
based on will just say it's a fifty mile trip to calculate what our SMA time and
round is going to be and our fuel burn at say eight gallons per hour. And of
course the fuel burn comes from our crews performance charts so that's how
you're going to use your E6B to calculate you ground speed and wind correction angle given
that you have your winds aloft and your true course begin with. Remember you can
always mix and match if you have your final answer you could always calculate
what the winds aloft are, you could calculate really anything as long as
you have the necessary givens. Hey guys! Thanks so much for watching. If you have
