Very nice explanation! 4 years ago, when I started to learn this theoretic part for flight simulators, I couldn't even think about the aviation channel, where I can find all info in 1 place. And personally I would like to see a continuing of videos about 737 procedures (climb, descent preparations, etc.). Wish you great day, as always 👍🏻
Really do appreciate you taking the time to make these videos to share you flights with us here in youtube land. Really wish I had these kind of videos to watch when I was a kid. Keep up the great work and keep on inspiring and informing people about aviation.
Раз уж вы принимаете заказы, то послушал бы про визуальные заходы (в мире в целом и в Борисполе в часности), визуальные вылеты (в Борисполе в часности). Про разницу между FAF ( FF36R D5.5BRP) и FAP. Про высоту FAP 3000' и 4000' в Борисполе, (где начинать снижаться по GS с 3000' а где с 4000'). Почему (в Jeppesen) для некоторых аэродромов для захода ILS указывается "MANDATORY" возле FF, а на некоторых нет. Спасибо.
Excellent! You make an awesome teacher! When you directed me here... first thing I thought of was... the barometer changes with the weather! You covered all my questions! Lol You Nailed it Sir... Thanks!
Thank you for another awesome video Denys! I would like to suggest airspeed for another video - IAS, TAS, GS etc and how it relates to pressure. Great job.
Oh God, Denys, I do love such technical videos! Thank you!!! As for me I would like to hear about speed measurement and hydraulic systems of Boeing 737NG, how they are designed, work etc)
Great information. Had not even considered how vertical separation might change with pressure changes. Have also heard of ground proximity radar. Gather that is seperate from the altimeter, though related. Thank you again for another great video.
Hey its 3am for me in USA I want to be a boeing 737-800 pilot when i grow up. I'm 16 now and did my first solo flight in a cessna 172. Best feeling of my life. I wanted to be pilot since 3 years old and your videos give me more inspiration to do so. Thank you so much for these helpful videos!!!
Hello Denys, I would like to thank you for increasing my understanding in this topic as I also learn this in school. Just asking, what would be the best and most effective way of handling these 2 emergencies? (Cabin fire and Complete loss of hydraulics). It has been on my mind and am interested in knowing the answer
Glad it was helpful! In situation you described, no matter what but if you have uncontrolled cabin fire you need to land as soon as possible. Fire on board is the worst case possible...
Wow!!!!!!! In English and soooo simple way of explanation! Thank you, captain Denis! Would like to ask you: in charts for Boeing 737-800 NG what altitude should I take for "minimums"? A, B, C, or D? Thank you from Zaporizhzhya))
If you’re some where at 3,000 ft on final approach, and the QNH is 10.20 Hp, and field elevation is 433 ft, how then do you calculate how many feet to land? From the altimeter should you aim to torch down at 433 ft being the field elevation? I have tried aiming to land at 433 ft from the altimeter, but it doesn’t work. I would finally torch down at 344. Pls how do I calculate it right?
Hi. Do you know a cheap standalone instrument that can measure the pressure inside a hyperbaric chamber in ATA or psi to at least 3ATA, no need for exact accuracy. Is there a wrist worn unit that can do this. Thanks for your help.
Do you mean that what actually happens at higher Flight Levels during flight when your aircraft is set to Standart Pressure is that the aircraft is actually changing its own altitude relative to the ground level, if it passes from area to area where the atmospheric pressure changes and it sorts of drifts up and down(again relative to the actual height between aircraft and ground?) I didn’t get the wavy lines that you drew near the end quite yet. 😮
i wanna ask one question, example in WIII/CGK they have transition level : FL 130 and transition altitude : 11000’ what they mean? is it transition altitude used for departure when passing 11000’ they change to std and transition level used for arrival when they use std and passing FL 130 they must change to local qnh? is that the point for transition level and altitude?
Yes, my friend, you are absolutely right. Transition altitude is fixed. Transition level may be changed, you may find it in ATIS information, or it may be given by ATC...
Perfect explanation denys🙏🏻 I just have a question,Considering ISA condition when we climb, our air pressure will be lower 1 in/hg or something around 33 mb per 1000 ft,so if we divide 1000 by 33 we reach the number 30 ft per mb(approximately). I wanted to know where does 27ft come from?😅
So there is a whole bunch of those Q codes: en.wikipedia.org/wiki/Q_code - do pilots and ATC know and sometimes use all of them, or the ones in this video are the only ones used? I think so far on videos which include some ATC communication I've only encountered QNH...
You need a flight plan usually... a 737 will burn 5,000 pounds (750 gallons) an hour. These are approximate figures, and the conversion between pounds and gallons is conservative.
@@PilotBlogDenys Indeed. But GPS calculates altitude too and it can easily calculate current vertical speed based on climb/sink rate. So, in theory at least, it should be as good as ILS glideslope because a GPS system with all maps loaded, knows where you are and where the runway is located and is able to compute your required descent rate for landing. With GPS and Galileo combined (let alone GLONASS and the Chinese version of GPS), accuracy is reaching 99.999.... per cent. Satellite navigation is able to provide vertical navigation just like ILS, at least in theory. I am not sure why airlines don't use it for vertical navigation, together with ILS. GPS knows your current altitude above sea level and also the airport runway's altitude above sea level, as long as airport location data is stored in the GPS device. This way, it is rather easy to calculate the desired descent rate in order for the pilot to set the correct vertical speed for a successful landing. The glideslope diamond's position can be calculated at least 100 times per second for safety reasons. We all know that a GPS device informs you about ground speed, elevation asl and current location. GPS is a 3D tool but in aviation is sadly used only as a 2D tool. GPS has the potential to become an alternative method to ILS vertical navigation.
This is all fine and dandy until you real lies that you can not have a pressure next to a vacuum. The only way you can contain the vacuum in that tube is by the tube and the mercury at the open end of the tube. "If" "space" is a vacuum how can you have any pressure next to it?
@@PilotBlogDenys Thank you sir. Each description that you provide included a tube. A container for the vacuum. Am I to understand that you agree that in order for there to be a vacuum it would need to be in a container?
Well the tube most likely is not strictly speaking vacuum, it contains some amount of mercury vapour, but it is negligible and taken into account for these measurements anyway. But what do you mean there cannot be vacuum in space? Earth atmosphere is just really bigger than we normally think it is, for example ISS is still in the Earth atmosphere, which if not for constant orbit corrections would lead to it slowing down and falling back to Earth. Further from Earth you can have vacuum. The gas around planets is held by gravity, so it is not like vacuum outside is going to suck the atmosphere out if that is what you are worried about.

27ft is normal pressure change per 1hpa or 1mb in atmosphere.
