Physics of Flight - Pivotal Altitude - Lesson 6

[@silverskaden]

takes a special breed to think of eights on pylons in this manner...I aint that breeed

[@colinboone9920]

Ikr, I came here looking for the maneuver demonstration, but I just watched the whole thing 😂 fascinating actually

[@FarmerBoyJake]

Lmaoo ,I’m with you on this one

[@silverskaden]

Thanks for taking the time to make and upload this video!

[@Stankinator911]

This is great. I was looking for something totally different about eights on pylons and came across this, and I'd always wondered how that formula came about. I never really liked the use of unitless constants in these formulas, but they're all over in aviation. Good to finally see where this one comes from.

[@CaptainReverendo]

This was awesome. Sometimes an understanding of the granular gives a much clearer understanding of the big picture.

[@mattfromowitz5690]

This video was very mind-opening.

[@bavareze]

i've been looking for this for a long time

[@crazypilot4017]

7:51 - I'm still taking a drink of water and trying to digest this....good stuff here sir :)

[@flyn4life558]

what high school did you go to so I can send my kids? because I differently didn't learn this math in the 11th grade.

[@GZA036]

You start out at some radius from the pylon ground speed necessitates a specific rate of turn rate of turn is determined by angle of bank (and TAS) the altitude must be changed so ^^that angle of bank points your lateral axis directly at the pylon Now you are at the pivotal altitude

[@ariacxariacx8692]

more confused that at the begining

[@chanio1179]

**looking at my physics score** Oh damn.

[@yoloolo3790]

This instructor is a treasure!

[@WilliamBowen-y7u]

very helpful, thanks

[@benfrancis2839]

This is fricken awesome

[@supraise]

Some sexy ass Shit. I actually followed, and understood. Thank you.

[@noonelimits]

the Entry should be 30 degree or 45 ??? 1:22 '

[@baddadjoker9570]

Me, with a GED after dropping out in 10th grade and an associates degree, totally feeling like I missed out.

[@sentinelese6717]

Physics is awesome :)

[@journeytoatp6317]

I just imagine that my tail gunner must take out the pylon. If he doesn’t we die. So keep the line of sight for him. But this answered all of my questions

[@wessamhanafy7289]

Amazing video the only problem is the sound of the marker is killing me 😅

[@flyobie]

Radius doesn’t matter? Why does it say in the flying handbook under common errors “failure to fly constant radius turn”

[@ERAUSpecialVFR]

You must be confusing this with one of the other Ground Reference maneuvers.

[@clr4tkoff1]

"Failure to properly execute constant radius turns." is in the AFH page 6-18 in the eights-on-pylons section. Your spoken comment "the radius doesn't matter" during the formula discussion was just that pivotal altitude doesn't vary based on radius, bank angle does. Maintaining pivotal altitude would maintain the same radius, right?

[@davidvirgilio4166]

Great video! Makes me wonder why non metric units are used in aviation... heh Also minor nitpick: at 13:30 you say accelerating to 66 mph is one G of forward acceleration, which is correct. You compare that the gravity which is one G down, which isn't 100% correct because there's also a force up from the ground keeping acceleration zero.

gotem

[@jeffreyhughes7107]

Nautical miles are used because 1 degree (latitude and longitude) is equivalent to 60 nm which is called a minute. Nautical miles are used in maritime navigation too. People drive me crazy with their METRIC FETISH FANATICISM. I never see people gripe about time and music not being measured in units of 10s.

[@colinboone9920]

See? Physics can be fun! Professors just need to give students some real life scenarios... if only everyone were a pilot

[@ItsAllAboutGuitar]

I would be your friend. This is so simple and straight forward. I simply can't understand why most people freak out thinking this kind of stuff is complicated.

[@ryanfife8166]

how do you not think is complicated brother

[@Limjahey52]

“Simple 11th grade trigonometry and physics” lol what planet do you live on pls explain

[@olafv.2741]

Nice explanation. Pitty that most of the time is wasted fighting the stupid units used in aviation. Flying would be just as nice in SI units. Even the base SI units can be used without running into weird numbers that require prefixes. What is wrong with flying 67 m/s at an altitude of 150 m after a takeoff from a 2200 m runway. With sufficient kg of fuel, you can burn g / s without the risk of running out of fuel. Planes crashed after running out of fuel after a mixup between gallons/pound/kg... Yes, they went to the moon with inches and pound, but it would have been much simpler using SI units. So weird that there are still 3 countries NOT using SI units. Two of them are underdeveloped.

[@ik04]

I did not hear an explanation of what this looks like out the window and the control inputs needed to maintain the pylon position. I stopped listening to the math after two minutes...

[@call911forcookies2]

knots^2/foot; lol rip SI

[@stanspiper]

This is not a friendly video! Think back to Trig Class?? Come on!

[@patbrown1808]

11.34 to be precise :-)
