Private Pilot Tutorial 7: Flight Instruments (Part 1 of 3)

[@marcemarce9821]

The best explanation ever, I am just starting to read about Plaines & understood a bunch. Thank you thank you

[@sajeevp.v.9682]

I'm not a master to find the error in this section but the voice of the teacher is lovable and earnest ..

[@tifk8864]

Actually such a good video. All concepts are explained clearly and now I have a great understanding of the way these instruments work!!! Thank you very much!

[@tifk8864]

Just tried out the quizzes on your website. It's amazing and such a useful tool for learning, I'm going to be watching all your videos!

[@wadepatton2433]

Tech note on the video production: "Surveyed" altitude is the correct spelling, rather than what is used in the graphic at 11:46. Says this surveyor, because training/reference materials should be as free from error as possible. BTW, Our benchmarks for elevation are usually set with about a 0.05' margin of error. That's +/- 0.6 inches and is close enough for most uses.

[@rooseveltdumornay4954]

That was very helpful. Thank you so much for this video.

thx u i can’t believe that i found this ur content is amazing

[@jorgeetrevino6790]

Excellent presentation, very informative. Keep it up!

[@danielocean2665]

So... At 10:32, does that altimeter not show about 555 feet, not 540? Or am I just a lil slow? Please, help my understanding, and only give me a medium roasting. I like my steak rare, after all.

[@petregurau8431]

When you zoom in you should show up the arrow on, so we can see what you are talking about.

[@bikashbhagat118]

Thank you for the video. Found it a good reference😊😊

[@marcemarce9821]

The best videos, very clear explained

[@smwagh123]

superb explanation

[@davidwallace5738]

Thank you very much for posting!

[@gwosapatbo513]

So the altimeter is reading neither pressure or density altitude but an approximate true altitude?

[@michaeleasler5249]

At 9:27 the word 'separate' is misspelled. Otherwise great video.

[@mattzoom8656]

Really dude? Are you fucking serious?

[@wadepatton2433]

@@mattzoom8656 Yes. Reference materials should not be polluted by misspellings or errors of any nature. This can be extremely important when reference important things like how to keep an aircraft in the air. This specific error is unlikely to be problematic, but that does not change the principle that reference/training materials should be as error-free as possible. Different letters make different words. Different words mean different things, and while this one (or the other one I noted elsewhere) obviously have little bearing on the safe operation of an aircraft, some other misspelling going unchecked- very well could. So. Yeah. We are "fucking serious".

[@casst346]

at 5:19, how does the aircraft height stay the same when flying from a high pressure to a lower pressure atmosphere area? I mean is the pilot lowering the aircraft when he sees the altimeter (without adjustment) going higher as he moves to a lower pressure area? If that is the case, i can see that by the pilot lowering the aircraft to keep the altimeter reading the same, in the end without adjustment he is now lower than he thinks...Im just trying to be sure i understand that the aircraft is being lowered by the pilot per the current altimeter readings without adjustment...is this how the aircraft in the end is lower than it should be..

[@gautamgandhi6621]

Your understanding is correct

[@chancellorweeb3538]

Thx greats job on vid hope others get involved in flying 👍

[@mshell1959]

Very good video!

[@kenziegardner5230]

randomly watching this video while at work and they mention Abilene… I work at Abilene FBO😅😅

[@Sky_Burger88]

So can someone help me understand altitude density? It seems if I'm flying at 5000 feet and I fly from warm air to cold air the air would become more dense as it gets colder. So if the air is becoming more dense wouldn't the plane fly higher to maintain that 5000 foot indicated altitude as it senses the air is more dense therefore it's going to fly higher to get back into the thinner air. Am i correct or am I not understanding this?

[@snipinglive5798]

GS Wing Nut I had this same problem. Cold air is more dense but less pressure. Hot air is less dense but more pressure. Example: take a pot and put water in it. Then put the lid and freeze the water. The pot will not build up pressure and explode. Conversely if u took the same pot and boiled the water, the lid would pop off and explode. Think pressure not density

[@leejunghoon1156]

G S you are dealing with two variables with one equation. Set the pressure and never change it. Than you will see the problem. Imagine same pressure air with different temp.

[@craigbrownell1667]

[6:00] ... I only have ~41 hrs in a single engine, but this part of the video is unfortunately wrong, if I have my physics right. Cold air at the *same altitude* is denser than warm air at that altitude. If you fly straight and level into a cold pocket, your indicated altitude will *drop* ... your altimeter will "think" that it is lower to the ground than it was before because the pressure has *increased* ... therefore you are actually *higher* than your altimeter reading suggests. *Not* lower.

[@georgeallensmo]

Craig Brownell

[@akfox38]

This is sometimes a confusing one Craig. I had to look it up again to remind myself why the the saying "From High to Low Look out Below" applies to both pressure fronts and temperature when flying. If you fly from a high pressure area to a low pressure area and don't adjust your altimeter, it will read higher than you actually are, hence the warning from high to low look out below. But this also applies to temp. From a high temperature to a low temperate crossing results in the altimeter reading too high as well. It's easy to confuse this one as we think cold air is more dense than warm air so it should be considered the higher pressure, but it's not. The cold air is related to lower pressure and the warm to higher pressure.

[@paulbergman8228]

Craig Brownell Hi Craig, It took me awhile to get this also. Think of the pressure level as part of an accordion that is sealed. Take the measured level of the expanded accordion at 29.92", now cool the air inside the accordion, and yes it becomes denser and the accordion does what? It is now not expanded at 29.92", but it is shorter, let's say 29.50" high. The weight of the air inside is still the same, and the pressure of the air is still the same, yet, the length or height of the accordion is different. Your ruler still says it should be 29.92" tall, oops! You see, your altimeter is just like the ruler and a specified volume of air, at that temperature and pressure. You can look at it another way, stand on a pole 1000' tall. Set your altimeter to 29.92", now add heat to the air. The air expands and becomes thinner, and the altimeter will read higher as the air expands, but you are still at 1000' on your pole, or cool it and the altimeter reads higher on your pole. But, you are not a fixed height in the airplane, you follow the altimeter when it reads 1000', so now you see that as the air cools, your plane follows the altimeter's 1000' reading and goes to a real lower height above the ground, and v.s. for warmer air.

[@vorpalsword3991]

Thanx guys for clarifying that for me also!

[@Sky_Burger88]

I'm a pilot in training. When I saw the handy saying "fly from warm to cold Look Out Below", that seemed backwards. It seems if you fly from warm to cold you will try to fly higher to maintain the same altitude above sea level. Not fly lower. Which is correct? I fully understand that flying from high pressure to low pressure could be hazardous but I think they have their temperature formula backwards.

[@Sky_Burger88]

• Does this video series cover all of the content that would be on the knowledge test for the FAA exam? In other words, if I watch all of these videos am I receiving all of the content I need to sit down and pass the test? 🛩

[@coreyyoungblood3811]

I doubt it, plus for the exam you need to study intensely, and there are numerous handbooks that you need that are all quite in depth, all written with the FAA exams in mind. I highly doubt that you could get enough from these videos to pass, but they are absolutely informative.

[@prevegsanthosh9165]

I clearly got your point of confusion.... One thing u have to keep in mind in that after a certain FL (about FL180), high pressure systems will have higher temperature and low pressure systems have lower temperature!... What you are talking about is absolutely correct but thats for the pressure near the surface..

[@wilsonkamau49]

Yo man I was having the same problem. The issue is your thinking about air density and air pressure as being the same property. Increased air density will cause the air molecules to be heavier. Thus, gravity will have a greater pull on the cold air molecules bringing them closer to ground level. Cold air will 100 percent be more densely packed closer to ground level. However, as you start climbing the air column, you will find that the gradient from densely packed air to sparsely packed air is more extreme, causing the cold air to be less dense at cruising altitude, meaning lower air pressure than standard, causing the indicated altitude to be greater than true altitude.

These videos are too vague and are really not explained very well for complete beginners.

[@hayleyyn]

I believe this is more of an overview to supplement your actual training/education.

I don't know how a flush toilet works, but that doesn't stop me from using it. Time much better spent on how to read instruments rather than the complicated principles behind them.

[@gregory.chalenko]

What if your toilet stops flushing, and there's no plumber nearby, and your date is coming in 15 minutes? If you know how to use a bucket of water and a plunger, you can avoid a dangerous situation. Same when your pitot tube freezes. You better know how to detect it and what to do.
