Clear explanations, made even clearer by your effective animations. THANKS! (And please don't let anyone give you grief about mom being overweight. Either you account for her having had too many bon-bons BEFORE taking off, or she crashes right along with you AFTER taking off!)
I was lied to in 1994. Your most excellent video just helped me learn the truth. I was told that in a fully fueled 172, if a 180# long-legged pilot took an average sized couple up, who are both in the back seat looking forward to getting in the mile high club, a bag of water softener salt had to be put in the front passenger seat to balance the plane. This is not true. The stupid bag of salt wasn't needed at all.
Fantastic job! You have an excellent ability for explaining the concepts required for a private pilots licence. Thank you for all your efforts in putting these videos together 🙂
Nice job covering weight and balance. This topic scares a lot of learners, probably because it smacks of physics and math. You did an excellent job of explaining it. Well done!
Thank you so much! And I appreciate you pointing out that mistake in the first version of this video. I’m not beyond Making mistakes. I appreciate the help!
@@FreePilotTraining None of us are beyond making mistakes. I'm just glad I could help. That's one of the nice things about the flying community: we look out for one another. Sometimes all it takes is a second pair of eyes.
Im currently learning flight planning - 1st chapter on weigh & balance nicely narrated. I am cross referencing my reading with this channel. It is super easy to understand.
Thank you for these excellent videos. Just a note. The movement needed is exactly 2 inches. The rounding of 500/950 caused the error of ~0.014 inches in the CG shift. If you write out the formula, it is pretty friendly: 250/950 = (500/950)/x 250=500x x=2
I'm not a pilot but I like airplanes. I knew that weight and cg were important. But didn't know how much detail there is on them. This video really put some light o this matter for me. I enjoyed. Thank you very much.
Having watched a lot of online PPL training videos, I can confidently say your instructional content is some of the best! 👏🏼 well done and thank you for creating this channel
I’ve been watching them all from the beginning over these last 10 days. This one was great. I learned a lot which is why I watch them but it was also fricking hilarious.
time stamp 14:40 you said 20/40 is .5, that would be a positive number, then later you called it -.5. I dont see where the negative came in. However I do agree with moving the 10 lb weight to the left .5 inches. Can you clarify why you called the .5 negative???
If you move left of the fulcrum it's negative, to the right is positive. Here, the weight was positive .5 to the right so he moved it left. That's when it became negative.
Your vids are awesome - I had a quick question - How would one have a Forward CG or calculate that? The chart shown in this video (as well as the C172 training supplement I fly) only shows the inches aft of the datum? Where would we find a Forward CG. Thanks!
This is a good question. Remember, our measurements are all made from the datum. It doesn’t matter where those measurements start, but on a specific aircraft, the measurements need to be made from the same spot. On 99.9% of aircraft your forward CG limit is still going to be aft of the datum. They are telling you where that spot is in relation to the datum. No manufacturer does this, but I could take all my measurements from the tail. In that case, the tail would be my datum and ALL my limits would be forward of the datum. Hope this helps
I'm confused.At 20:04 the numerator is -.53, but when you cross multiply it changed to -.15. Then at the round 26:35 mark you said the arm was 95 with 50 pound bag giving a moment of 5, but it was 4.75. Another question I have is all the test questions I have seen so far say the empty weight of the plane includes undrainable fuel and oil but your example shows deleting the oil listing, is that aircraft specific? By the way I have already completed the sporty's PPL course and your series are so much better at explaining the information.
Thank you! Yes, there’s a mistake there. I accidentally calculated wrong the first time and redid that part. The answer at the end is correct, but there’s an incorrect number in there for a bit.
How are planes like the Airbus A220 and Boeing 717 able to balance themselves with a 5-abreast layout, since the 3 seats on one side have more weight than the 2 on the other?
Hallo sir thank you for a well illustrated vidoe....can you please do a vidoe on how to place the control surfaces when maneuvering on the ground with respect with the wind direction,,, it would be of help during my Ppl GFT which is happening in 3 weeks time
You’re welcome! I would love to make the video, and I eventually will make one on that, but I don’t think I’m going to be able to do it in the next 3 weeks. I’ve got a lot going on. I’ll see what I can do though
Based on the moments on the bottom of the chart. As you can see the moments are in increments of 1,000. So, we need to move left on the chart about 1,000 inch pounds
@@FreePilotTraining I have watched many of the videos in the Private Pilot Ground series. I really appreciate your time making those excellent contents, very easy to understand. I'm wondering about something, besides the series, what other videos in your channel that can be useful for the knowledge test exam? Honestly I'm just looking to simply pass the test, not a high score due to busy work-life schedules.
@@myyouth6864 thanks! I appreciate that. The ground lesson videos will get you there. I try to include something in every video that pilots can learn something from though. I think that’s important
Just withdrew my profits a week ago, it was so shocking when I withdrew $32,450 knowing I invested $3,000. I wish I could reinvest but, too much bills 😩
-15 is wrong. When I first calculated this -15 came from some wrong data and accidentally got left in the video. All calculations are based on -.53 which is the correct number
@FreePilotTraining Thank you for clarifying. I have no idea if I'll pass a class 1 medical so I can become an ATP, but I'm doing some preemptive studying anyway. Also thank you for having this series up. ❤️
There’s a mistake in the video at 17:49. -.53 is accidentally changed to -15. The calculations are made with -.53 so the answer comes out correctly, but -15 is a number from a previous calculation that somehow slipped through.
Yes, the weight is balanced on the center of lift, but the weight IS centered on the Center of Gravity. The center of gravity on a seesaw is not necessarily on the center, but it balances on the center
That should be -.53. There’s a mistake in the video at 17:49. -.53 is accidentally changed to -15. The calculations are made with -.53 so the answer comes out correctly, but -15 is a number from a previous calculation that somehow slipped through.

Your calculation is odd. We just need to makes the moment equals to either side of fulcrum. So just minus the right moment 500 LB*Inch. Which moves the 250 lb 2 inches leftward.
Best video on weight and balance on the internet!
Thank you so much for that!

Please , Explain to me why at minute 20:14 the equation suddenly changed from -.53 to -15. I couldn't understand this sudden change

There's an error in your equation at 20:17. Number changed from -.53 to -15. Just an FYI, as the calculation was still made correctly.

What do you mean all the weight balances on the center of lift? I thought all the weight is concentrated through the center of gravity?
Yes, the weight is balanced on the center of lift, but the weight IS centered on the Center of Gravity. The center of gravity on a seesaw is not necessarily on the center, but it balances on the center
The cg doesn’t change if you increase the AOA unless you have a bunch of loose cargo
It DOES relative to your center of pressure, but you are right. It does not move relative to the datum
@@FreePilotTraining true. But yes I was talking about the datum lol. Great videos
hey vid is amazing but how 950x-15= 503.5??
That should be -.53. There’s a mistake in the video at 17:49. -.53 is accidentally changed to -15. The calculations are made with -.53 so the answer comes out correctly, but -15 is a number from a previous calculation that somehow slipped through.

Sometimes my tails a little heavy in the Herc, and it feels like the plane tries to jump off the ground on Takeoff sometimes lol

now we really know why airline are so strict with weight because it center of lift and those airplane plane are massive so imagine that weight.
