Weight And Balance Part 3: The Calculation

[@Mcmcmoney]

⚠️🔴NOT ME HERE AN HOUR BEFORE CHECKRIDE STRESSING OVER WEIGHT AND BALANCE! Seriously though thank you sm for this video it helped clear up a lot... you earned a sub!

[@maxcfi7718]

good luck!

[@reeseprice82]

How'd it go?

[@PylotGuy]

Are you a pilot ?????

[@londonmoren9611]

Same

[@userinterfacenotfound6011]

Haha I might be doing the same

[@klugaric]

In the equation Weight x Arm = Moment, why did you divide both sides with weight because from mentioned equation Arm = Moment/Weight already? It is not needed to divide it with weight.

[@maxcfi7718]

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

[@klugaric]

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.

[@maxcfi7718]

@@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.

How do you find the empty weight

[@Tyleraviator99]

its on the weight and balance sheet. if you remember arrow, the weight and balance is the most up to date weight and balance for said aircraft

[@PylotGuy]

Wow thank you so much !!!!! This was the best explanation I’ve found… so many videos that are 30-40 minutes that I don’t understand and this completely broke it down to simple English, thank you !!!

[@jamessock1091]

PLEASE SOMEONE HOW DO YOU FIND THE BASIC MOMENT OF A PLANE I’m going actually insane?!? I can’t find the arm of empty weight for a Cessna 150 1976’s Commuter II.

[@motogirlz101]

You look in your operating handbook. Every plane is required to have one. You could also search online for the same POH but it would probably be slightly different b/c the arm changes depending on what work has been done on the plane. For ex. My 1967 C150 G has arm at 32.56 for empty weight. But that could be slightly diff from someone else’s same year and model plane b/c they have diff avionics or other things installed in their plane.

[@flyingplumber3565]

I’ve never truly understood weight and balance until now . Thank you !! lol

[@ActioJjunky]

You made this incredibly easy to understand

[@diaryrecorded5524]

hey this is a well put together video! thanks!

[@Purpatratur]

My instructor was saying something about usable, fuel, and non-usable fuel at takeoff. so if you had 50 gallons to calculate you calculate 48 instead usable fuel

[@CashMoney5280]

Great content! I appreciate the knowledge THANK YOU.

[@sunandgratitude7536]

Thank you so much for this. I can't tell you how much the visual helps. I was struggling with this but you've made it crystal clear. Thank you!!

[@redbaron8989]

Excellent tutorial. Best I’ve seen. Love how you incorporate using the different charts after crunching the numbers.

[@chifordenis]

Thanks for the video. You made all clear!

[@jfvillafuerte]

Thanks for the tutorial, this information is very helpful!

[@demoid018]

Can you make video how to work meagntic compass in aircraft and error face during flight

[@timdiggens7025]

Super helpful to recap pre check ride

[@Yinanabugoogle]

Great video 🙌🏽

[@niteshgiri228]

Nice video

[@travisjames8087]

Exactly what I was looking for. Easy to follow, each component was adequately explained but to the point, the data was laid out beautifully. This is professional teacher level. You rock man!

[@dancrosby6091]

Liked this video so much I subscribed. Very informative and easy to follow.

[@_miguel_tenorio]

I really needed to watch this. Thank you

[@Rajeesht71]

Can you please explain how to calculate or find Dry operating weight index?

[@mad4274]

who ARM for the empty aircraft was calculated the 39.6 vale?

[@MUADFLYINGHIGH]

you are doing a fantastic job!!!!! i really appreciate you. need more videos keep going...

[@thevinylreview]

Great explanation thank you so much

[@brianclancy5124]

maxcfi, thank you so much for this awesome, visual video my man! I'm writing curriculum for an aviation maintenance high school course, and this video was so clear and understandable! You rock dude!

Any chance you have a pdf of the drawing? Great job….thank you!

Thanks for the video.

Thank you

[@torakattv]

thanks what a great video! but can i ask where to get the table of center of gravity limits?? i'll just use to as my reference for my project. Thankss!

[@bhm1712]

From the pilots operating handbook of the aircraft you’re doing the calculations for.

[@mothanna2320]

If my weight in 87 kilogram how to convert it to pound ?

[@rolandogomez1308]

87 x 2.2046 = 191.800 lbs

[@mca1901]

❤😂😢😅

[@Tyleraviator99]

hey, on a cessna 172 basic empty weight includes unusable fuel so for fuel you would only do 37 gallons (if you are on a separate model then disregard)

[@maxcfi7718]

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

[@Tyleraviator99]

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

[@maxcfi7718]

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

[@Tyleraviator99]

@@maxcfi7718 ok. Thank you!

[@NasirKhan-l9n3j]

Can someone explain how the arm length for "empty" is calculated?

[@HighFiveAviation]

I think the “empty” is the engine place because what else could be 39.6 inches and weigh so much?

[@HighFiveAviation]

sorry I was wrong the datum line length was 39.6 inches and the weight of the empty aircraft was 1454 lbs

[@Mcmcmoney]

No clue I just found it in the pilot operating handbook

[@Iamamclaren]

How do you determine the measurement of the seats to the datum

[@maxcfi7718]

this information should be in your airplanes operating handbook

[@Iamamclaren]

Tysm I fly the cj4 in the sim and this really helped me understand the concept
