Hey everyone, Jason Schappert here of MzeroA.com
And today, I'm in the studio, because
I want to share with you and talk a little bit more about aircraft
center of gravity, and help you understand it better, we know
and we say from rote memorization on a checkride, yes, a forward
cg is more stable, an aft CG is less stable
but do we know and understand why?
Let me help you, I'm a visual learner, and that works
for me, let me share with you a great animation from inside the
our brand new private pilot ground school, we just spent the last year actually
reshooting our entire private pilot online ground school with great animations
like this, so let's look at this here together, so there is 23 mike zulu
now I want you to remember that the center of gravity is the point
at which the aircraft will balance, it's what the aircraft
literally moves around, it's that center of gravity
that's a nice forward CG, it's said to be more
stable, now if we move that more aft like you can see there
we are inherently less stable.
Why is that the case? Let's now look
at our actual model here of two three mike zulu,
if we say that an aft CG is less stable, why is that the case?
Well, it all has to do with leverage, it all has to do with that
station arm. Let's think of an extreme scenario, like
a spin. If I enter into a spin, what's my spin recovery?
procedure: power back, ailerons neutral,
and rudder opposite, right, and then elevator
down, too, to help break that and get the airplane flying again.
Everything hinges back here on this tail, it's very important to us.
If I have a forward CG, let's say my CG is positioned just right
underneath the pilot's seat, the distance from the
CG back to the rudder, is a very long
arm, I have lots of leverage, lots of
rudder authority, you could say, thanks to that long arm
the distance from the Center of Gravity, back to my tail
section, now, if I have an aft CG,
let's put it back here behind the baggage compartment now, that arm
is much shorter, will it still work, yes, but
I have less power, I have less leverage, think of it this way,
why is the door handle in the door in the room you're
sitting right now, why is it so far away from the hinge?
Well, it's to get leverage, right?
What if you took that door handle and you moved right to the middle
of the door? Could you still open the door, well, yes. But
what would happen, it would require more effort, more
strength on your part because you've shortened the arm.
The hinge hasn't changed, but the location of the doorknob
has changed, we've shortened the arm, we've shortened the leverage.
That's what really happens when we have an aft CG.
We've shortened the arm, the distance from our Center of Gravity back to our tail
so we have less rudder authority with that,
and I love sharing these great little animations, just easy quick little tid bits
