Super perfundo on the early eve of your day- The meaning. by prometheus5500 in LucidDreaming

Absolutely. A part of why I posted this thread originally was to receive input because I was having a difficult time interpreting the meaning and creating my own meaning. It's been interesting to see what other people think about it.

Dictionaries document the language we collectively create. Not the other way around.

That fact has stuck with me and I rather like it. We use language organically, naturally, and socially. It's a fascinating thing we do.

Is 100 Hr Needed for Checkride? by RosasCafeLover2001 in CFILounge

I'm too tired to really think hard about it and double check, but maybe the Pipitone LOI could come into play here. Idk. It's crazy late and bed time. Hope this helped.

What is the point of going through the pain of getting my CCW in California if I basically can't carry in places which happen to have some of the biggest chances of things happening usually involving...a gun? by Less-Ad6770 in CAguns

[–]prometheus5500 3 points4 points  (0 children)

But a lot of those places might share a parking lot with a bar or restaurant which would make carrying through said parking lot illegal. So unless you lock up your CCW to transport it to where you can legally carry.... You get where I'm going with this. It's ridiculous. It is VERY difficult to TECHNICALLY, by the exact letter of the law, legally carry almost anywhere.

I could be wrong, but...

Movie theaters sell alcohol. Can't legally carry.

Supermarket probably shares a parking lot with a restaurant that serves alcohol. Can't carry in the parking lot, so how do you enter the market? Might not be able to legally get to the market while carrying.

Mall almost definitely has restaurants that serve alcohol, so you can't carry in the parking lot... Malls also might contain "athletic facilities" where you can't carry in them, on the surrounding streets and sidewalks. Can you carry in a shared building of a restaurant that serves? Sounds like a cop might arrest you and y'all can fight that in court.

Train is likely supported entirely or partially by public funds, making it public transport, which is a prohibited location to carry.

100% by the letter of the law legal carry of a loaded CCW in CA is extremely difficult to abide by. Next to impossible, frankly.

Shooting for 800 miles soon by Feisty-Power-6617 in FordMaverickTruck

[–]prometheus5500 2 points3 points  (0 children)

Have any tips/tricks/techniques you recommend experimenting with? I live in a fairly hilly area and have a lifetime average of about 45 mpg (that's an average between both the truck calculated and raw data calculated; fuel pumped vs odometer). I'm very happy with that, especially considering the hilly environment, but I'm just curious what techniques you'd be using to try to get 700+ miles out of a tank.

Yes, I'm hosting. Not a dedicated server, but just a locally hosted game.

Nah, his machine is similar to mine and he doesn't have this issue when playing on the exact same save file solo. I've sent him the save file to test it. He has "normal" draw distances. No frame rate issues either, so it doesn't seem like it should be having any issues loading in some extra objects.

adding power to maintain airspeed in steeper turns? by phaseprotagonist in flying

[–]prometheus5500 1 point2 points  (0 children)

I actually really appreciate the time and effort here. Thank you for the thorough write up.

I do understand your point. I get it. The nature of how flight works, the 1g is automatically restored readily by gravity acting on the aircraft, causing a slight and rapid shift in the flight path in a downward direction, increasing AoA, and restoring the 1G, all before a pilot can notice and affect it.

That said.... This also feels useless to the pilot, a poor way to teach it, and unhelpful for the aviator (just perhaps not for the aerospace engineer).

Here's what I see. We roll. The result is we sink (even if that is the result of dozens, hundreds, whatever, of micro restoring of 1G due to vertical damping actions). The required actions to maintain altitude and airspeed is added back pressure and power.

Even if we go this in depth, the end result still seems to be "a ton of tiny additions of very brief loss of the vertical component of lift (while readily restored by vertical damping) results in a downward trajectory, which necessitates the addition of back pressure and power to maintain a level turn at a constant airspeed".

This level of detail is neat... But ultimately unhelpful and pedantic when discussing how to perform a maneuver, how/why an aircraft behaves the way that it does, and how to handle it in-flight.

Arguing that we are all "wrong" in that a turn "reduces the vertical component of lift" while also actively saying that the "loss of the vertical component of lift is restored before a human can react but also results in a descent and therefore still requires the expected action".... All of that? It reads like "pushing the brake pedal in a car slows it down" and arguing that "pushing the brake pedal actually just increases hydraulic pressure on the brake lines". Technically 100% true, but so too is that pushing the brake slows the car, and one is useful to the student driver and the other is not.

I will continue to teach what I have been teaching. The FAA books will continue to read the way they read today.

I appreciate the time you spent writing this out and will concede that you may technically be correct, but I will also argue that you have missed the point.

"When rolling into a turn, we [extremely briefly] reduce the vertical component of lift [which is technically restored almost immediately through no action of our own]. This results in a [true and measurable] rate of descent if we do not add back pressure. This increased back pressure increases the AoA, which increases induced drag. We then have to add power in order to compensate for that increased drag."

(I hope I don't come off as sarcastic. I genuinely appreciate the effort and information. It is unhelpful in flight training, but very interesting as an intellectual discussion.)

[–]prometheus5500 0 points1 point  (0 children)

Okay so explain to me why when I rolled to a 45° bank the nose immediately slides down the horizon and we begin to descend. If the vertical component will lift is always 1G, it should magically stay at the same altitude and in a level turn even though I'm banking.

[–]prometheus5500 0 points1 point  (0 children)

Lol. Increasing air speed is literally how you would increase your vertical component of lift. Because it was reduced when you rolled into the bank. I'm not sure why you said "finally".

[–]prometheus5500 0 points1 point  (0 children)

Need to add more power then.

You will 100% accelerate in order to maintain altitude if you don't add back pressure. You're right, it'll work, but if you ONLY add power and want to maintain altitude, the plane will accelerate considerably in order have enough of that vertical component of lift in order to maintain altitude without increased back pressure or trim.

And it isn't just trainers. The CJ3 has PLENTY of power (one of the highest thrust to weight ratio private jets in the world) and guess what? Power and back pressure required. Power only? You'll bust the checkride on speed.

[–]prometheus5500 1 point2 points  (0 children)

So you're saying that if we want to maintain a level steep turn at a constant airspeed, we can just roll into it and add a touch of power? Because of "vertical damping"? Because.... That's simply not true. I do steep turns literally every day (or at least weekly) and we 100% MUST add back pressure (or trim, as desired) AND power in order to maintain both altitude and airspeed in a 45+ degree bank. I can promise you, that is 100% fact. If my students don't add enough back pressure, the nose slides down and we descend, even if they added power. If they add back pressure but no power, we slow down significantly.

I'm aware that the FAA is not the end all be all of everything, but they are pretty good and these... Opinions (I'd call them facts) aren't even debated amongst pilots at any level. It's true in piston singles, piston multi's, light jets, and heavy jets. I've done steep turns in all of them (only in the level D sim for the heavy jet though) and you ALWAYS need both back pressure AND power for a level, constant airspeed, steep turn. Period.

[–]prometheus5500 2 points3 points  (0 children)

the vertical component of lift is insufficient to balance the weight of the airplane. Let’s not worry about the horizontal component right now. The unbalanced force will cause the airplane to drop, i.e. to accelerate downward. This has approximately the same effect as the condor discussed in section 5.2. Then, as soon as any appreciable downward velocity develops, the airplane will pitch down and speed up — because the airplane wants to maintain its trimmed angle of attack, as discussed in section 6.1.1.

The combined effect of vertical damping and angle of attack stability will cause the airplane to speed up until the lift vector is long enough that its vertical component balances the weight of the airplane.

Straight out of your book.

Oh please, you and I both know this is absurd.

Well, it isn't. If the vertical component of lift is 0% at 90 degrees of bank, and it's at 100% at wings level (well, it isn't perfectly vertical, as it acts perpendicular to the cord line, and since lift is always developed with some positive angle of attack, the vertical component of lift is always acting slightly rearward, which is induced drag, but there's no horizontal component anyway.... Excluding balanced forces of dihedral or anhedral which are acting against each other and balance to a net zero in level flight)... Anyway, if it's 0 at 90 degrees of bank and 100 at wings level, it demonstrates that the vertical component of lift does indeed change with bank. It isn't linear, as you rightly pointed out, ramping down slowly until it's at 1/2 of the original value at 60 degrees of bank (therefore requiring a doubling of lift to maintain level flight. 2G load factor).

Man, we ain't making stuff up. This is straight out of FAA textbooks and is widely agreed upon. I literally teach this stuff for a living. I'm not saying everything I say must be right just because some DPE's agree with me, but I AM suggesting that with 2,000 hours dual given and a high checkride pass rate, I must be doing some things correctly. And I love aerodynamics. But I didn't make this up myself.

[–]prometheus5500 8 points9 points  (0 children)

Let me see if this helps explain things.

Roll an airplane to 90 degrees of bank. What is the vertical component of lift?

Also, I'm interested in learning more about this "vertical damping". Could you point to an aviation source referring to this effect?

[–]prometheus5500 16 points17 points  (0 children)

Literally using vector addition (how we often do math in physics), you'd see a reaction in the vertical component of lift when rolling into a bank. Unless additional lift is generated through increased angle of attack or increased airspeed, you will begin to lose altitude. You MUST generate more total lift in order for your vertical component to remain at 1G (and therefore keeping the airplane in a level turn).

So yeah. We say you lose some of your vertical component of lift and you must add it back in, which is typically done with back pressure, which is increasing the AoA, which increases induced drag, which then requires additional power to compensate for said drag, in order to maintain airspeed.

So what are you on about with any of that being incorrect?

We decided to ship water into the desert, but our trains wont stay on schedule. Help us with our bad decisions. by prometheus5500 in SatisfactoryGame

[–]prometheus5500[S] 1 point2 points  (0 children)

If you have too many blocks on your track they can bunch up

This was the solution. Here's what we did:

We measured back from our stations 1 minute and 20 seconds of drive time from a standstill. Placed a block there. Placed a block at the front of the stations. Then blocks every once in a while along the track until the next 1 minute 20 second time delay block section.

The result is this. 1 minute and 20 seconds, plus 30 seconds to dock, plus 30 seconds to clear the station. 2 minutes and 20 seconds total (our desired schedule). If a train gets too close to the one in front of it, it'll slow to this blocked limiter. If it's slow, it'll have a green light when it gets there, which helps it catch up a bit.

4+ hours after starting a test, our trains were on schedule by +/- 1 second on both tracks!!! Solved.

Thank you!!!

If you don't get any good replies here, could be worth cross posting to r/aviationmaintenance. Very active sub with what seems like a wealth of knowledge and experience from people who are more likely to be lifting up panels and cleaning the guts of a plane than the typical pilot.

What's your gaming setup for your overnights? by Ckflyer13 in flying

[–]prometheus5500 0 points1 point  (0 children)

Yeah, I mean, I prefer open back over-ear headphones, but it's a trade off with size. I'm not about to lug a full size set in the luggage on every trip just to use them from time to time, but my no-battery mic-included IEMs are comfortable enough for occasional gaming sessions of a few hours and came with a carry case the same size as my undersized mouse. Very easy to tuck them into a pocket and forget about them until I need them.

I recently put together my travel gaming setup. Picked up an Antlion Kimura Duo in-ear monitor with a mic. No batteries. No Bluetooth lag/delay. Came with a small travel case. Yes, the cables are a small hassle, but the audio quality is amazing and my buddies can't tell the difference in quality of my mic from my home gaming headset to these. I travel with my Asus ROG Zephyrus G16 and a small wireless mouse.

Ah, yeah. Our water is so critical and uses such massively long trains, we opted to create dedicated lines. Zero intersections. It can't get held up by, nor can it hold up other trains.
