This may be too late but the answers to your question is No. you cannot used to keep the aircraft coordinated. This will keep the aircraft from skipping and skidding; and potentially get yourself into stall spin situations depending on the maneuver you are doing. Rudder usage is very important during stall maneuvers.

@@nimbapilot6925 great thanks, so what does a coordinated turn mean ?

this is not a vacuum gauge as i’ve explained before. it is a manifold pressure gauge.

@@maxcfi7718 The manifold pressure is a vacuum the entire time the engine is running unless you have a supercharger ...the "pressure gauge will have numbers on both sides of zero .... all pressures are relative to atmospheric pressure ,,,, we do not take them to space to calibrate them .....

@@theiaminu5375 yes, but this is measuring the actual pressure in the manifold. hence why it’s lower when the throttle is closed and equal to atmospheric pressure when throttle is wide open (for a naturally aspirated engine.) my understanding is a vacuum gauge would measure the difference between atmospheric pressure and the manifold pressure, so it reads higher with the throttle closed. we do not normally measure vacuum on the engine in aviation

@@maxcfi7718 It's backward from what you would encounter in the REAL world ... low is to the left (counterclockwise)and high is to the right (clockwise) in every gauge you will find ....Even on a mass spectrometer ...

@@theiaminu5375 yes? and it is also on the manifold pressure gauge. not understanding what you’re getting at 😂

I think it’s because all the ground speed you lose with a headwind still appears on your asi. Like 120kt ias with a 30kt headwind your ground speed is 90 kts but the extra 30kt headwind is still giving you the 120kt reading on your asi. So the wind is constantly affecting the Ram pressure which is why we calculate groundspeed. Don’t trust me on that though I’m kind of dumb lol.

i was deriving the other version of the equation. to go from weight*arm=moment to arm=moment/weight you must divide both sides by weight

I still don't understand why. 😄 If 3x2=6, then 2=6/3 If weight x arm = moment, then arm = moment/weight. You get the same equation without dividing both sides with weight. So my question is why the one would do that? P.S. Thanks for the videos, they are very helpful for understanding my PPL literature.

@@klugaric when you divide by weight on both sides it is in the denominator on both sides. so you end up with (weight*arm)/weight on the left side of the equation. weight cancels and you’re left with just arm on the left side of the equation. on the right side, you get moment/weight and nothing cancels. so you end up arm = moment/weight. this is the process you’re doing when you go between those equations, whether you know it or not. you are smart enough to just see how the equation can be changed without actually writing out the algebra but that is what you’re doing implicitly when you change the equation in that way.

it was a plastic model i bought and built from a hobby shop! not sure the brand

you’re welcome! side note - I used to live in Liberia!

@@maxcfi7718 Oh really? Nice! how do you like being a cfi? we should link up sometime!

you need your true airspeed to calculate your ground speed. true airspeed plus headwind/tailwind component will give your ground speed

Think about it like this, you need to know rate and number of the air molecules passing over the wings, because the rate at which they’re passing impacts whether you’re about to stall and airflow is about to breakdown or whether it’s about to rip your wings off - IAS. You need to know the speed of the air molecules passing in general so that you know how fast the actual aircraft is moving through the air, regardless of the number of molecules, their temperature etc in order to work out how was you will arrive somewhere - TAS.

check the manual but i believe it’s 40 gallons usable, the unusable fuel is in addition to that

@@maxcfi7718 oh ok. I thought in a previous video you said that 40 is total

@@Tyleraviator99 it is total usable. we don’t count unusable, it’s already in the basic weight

@@maxcfi7718 ok. Thank you!
