The Ultimate Tutorial on Steep Spirals: Learn from the Experts

[@dustinwoodhouse1940]

You state that "clearing the engine" is an ACS requirement. I don't see that listed anywhere in the ACS definition of knowledge, risk management, or skills for this maneuver. Am I missing something? Good video, just wanting to clarify this one question.

[@vincelam1998]

Agreed. It's not in the ACS.

[@Vpmags]

The ACS references the AFH and you'll find it there. Happy flying.

[@dustinwoodhouse1940]

@@Vpmags I find no mention of clearing the engine in the chapter on steep spirals. I *do* see this reference in the chapter on simulated engine failures, as a suggestion: "An occasional clearing of the engine is also desirable." I don't see anything that would constitute an ACS *requirement*.

[@Vpmags]

@@dustinwoodhouse1940 AFH Chapter 10, page 3, paragraph 2. It provides guidance but limits verbiage to "should" not "must". If you are concerned, It's probably best to bringing it up with the examiner of the day to better manage expectations for the check ride. If you're just looking for clarification in general, ask your local FSDO. Cheers.

[@dustinwoodhouse1940]

@@Vpmags my only concern is people stating requirements that don't exist. Is this a best practice? Probably. An ACS requirement? No.

You guys have been putting out some good content lately. . .it just so happens it's the same content I've been putting out lately lol 😂 I'll put a video out and the following week you'll put one out on the same thing. Or you'll put a video out on something I have scheduled to go out the next week. My steep spiral video is scheduled for Monday haha. . .I am glad to see that both of our videos' messaging has been fairly consistent across the board though 🙌🏻

60deg of bank in a LEVEL turn requires 2gs and increases stall speed. In a descending turn, you're still at 1g and no stall speed increase. Stall speed increases with load factor, not bank angle.

[@IRAMightyPirate]

Beat me to it. Big mistake by the video makers confusing speed with angle of attack.

[@jimallen8186]

For a spiral, they should be pulling hence adding load, think first half of low yo-yo while never doing the second yo. Therefore we don’t know the g. They’re confusing purpose too. The text states for learning about near stall while the speech spoke of rapidly losing energy so as to expedite a landing.

[@Cosme422]

The music is killing me! Sorry it’s hard to watch any video of anyone explaining anything with music playing in the background. A message to the video editor. None of these videos should ever have music. These are not those type of videos. Thank you.

[@ahmadsamadzai8255]

I agree. I can't understand for the life of me why people put music on their videos. Ruining an otherwise very good content.

[@Bokosuka-yl7eq]

Bro you are a pilot, you should not be simply distracted by just music in the background

[@LouRC]

@@Bokosuka-yl7eq I’m also a professional video editor contractor for various TV stations and know that this video should not have music. lol

[@Bokosuka-yl7eq]

@@LouRC shush it chawg. If you can’t watch a video without expecting a bit of noise in the background, let alone on a plane, you’re dad should’ve left you on your mums back🤓

[@ahmadsamadzai8255]

@Bokosuka-yl7eq it's not just a distraction. It's annoying and in my humble opinion it ruins the content.

[@juanmesa4585]

How do you pick your loot up n the archer? And make the decision to start the turn. Thanks for the videos they have been amazing!!

[@derekec]

I didn't notice it till you pointed it out. "Now" I can't past it.

[@hdonner5960]

You don’t lose more altitude in a larger radius turn. When you bank 60° you have lost a considerable component of your vertical lift vector. Don’t take my word for it, compare a 60° spiraling descent with a 45° spiraling descent. You will see how your vertical speed increases profoundly and you subsequently lose more altitude per 360° turn.

[@nateliebherr]

I thought the video was good but lose the annoying and redundant music in the background it's just a distraction and makes the video quality far less. No need for music in training videos

[@jimallen8186]

60 degrees is not 2 g because you’re not holding level; picking a speed slightly above “best glide” may not be best either, the intent is rapid dissipation of energy, hence you either want to be really fast and, as able, toward max g load thinking parasite drag augmented with induced, or, if you can’t be fast, you want high AOA for gaining just the induced as your tool. Bleed the energy. That is the game. As for three turns, depends on how you’re given the maneuver. If you’re just doing it as a prescribed maneuver “let’s do the spiral,” sure, but if you’re presented with a scenario, you shouldn’t be slowing your descent rate for the sake of getting the turns done. I’ve done this in anger, it consisted of two Split-S at idle with speed brake though with minor extensions vertical down so as to stay fast and keep rapidly descending, then an oblique high g 360 which put me at a tight initial for an overhead break. Depleted the potential rapidly then quickly bled away the kinetic. PS - there is no best glide speed, only best glide AOA and such is only best in still air. We talk about AOB increasing g and pitch rate increasing g yet we never talk about steady state pitch lessening g.

[@JacobTyler-s8i]

you aren't pulling 2Gs in a 60 degree descending turn

[@briansantana3157]

Yup Even flight instructors seem to misunderstand that it’s not bank angle that increases G, it’s the associated load factor that you need to maintain level flight that pulls you down.

[@MRbuildingMR]

Yes you are, after you’re stable in this very long turn with constant airspeed. If you are pulling less than 2G, the airspeed will keep increasing. Put another way: it takes 1G to do a 60° turn, it takes another 1G to not accelerate downwards. It’s true for a short duration 60 degree turn you have a few seconds to do a decent turn without loading up before the airspeed runs away from you. But once you stabilize a long 60° turn it’s the same 2G.

[@JohnCaptainAmericanAirlines]

At 12 minute mark of video she states ACS requires clearing the engine. Please respond with actual ACS reference to this otherwise false statement.

[@Me37368]

It’s not in acs but AFH says it’s a good idea to do that

[@TiagoSeiler]

You're not wrong in that it's not part of the ACS, but when you point out a mistake in the manner that you did, you just come across as a douche bag.
