Dear friends and followers, welcome back to my channel!
Today weโll be looking at on โHow high can planes flyโ? What determines their maximum altitude? What are the dangers of flying too high? What are the Optimum, Maximum and Recommended Altitudes?
I hope all these questions will be answered in this video!
Enjoy!
Thank you very much for your time! I hope you enjoy this video!
Wishing you all the best!
Your "Captain" Joe
Big thank you to all other youtubers who provided me with the video material to create this video. Your content is highly appreciated. Please follow their channels:

Yes guys the legend is back.
But... He was always here... He didnt even take a break.
Legends never go.
he never left
He never left
Legend?!! Yeah right
The 747-400's ceiling is actually 45100 feet. Pretty high! And your slow continuous climb took 40 minutes.
Yes agree! One of our 747-400 the BCF recently flew from JNB to NBO at 45000 feet. I had never seen that before. But regularly at 43000 feet especially from EZE to UIO. Indeed 45000.
Well done Buddy!
@Aditya Shaligram the restriction by the manufacturer is always lower than what can be achieved, so if a pilot flies at 43000, he has a safety margin
so if i understand correctly there are 4 limits:
1. max height company/flightplan
2. max height atc/faa
3. max height manufacturer
4. physical max
Right??
@@flywithcaptainjoe can you please explain how to operate the radios and how they work etc.
"DEAR FRIENDS AND FOLLOWERS" never get old
Thanks

Welcome back... the ones that still know Captain Joe from his old videos... RESPECT๐ค
Thanks Andrina :)
Kennedy Steve always makes me smile.
Me to!
As a Boeing engineer I witnessed a 747-400 flight test where the airplane climbed above the maneuver limit altitude (where the amber bands came together) and continued climbing until rate of climb came to zero (slowly wobbling between 50 fpm up and down). The condition was very comfortable and just felt like normal cruise. It was fascinating to see the mighty 747 reach its performance limit. Thanks, Joe, for reminding me of this experience (and many others)!
It took you 40 mins to complete the climb (hope thatโs right, Iโm a bit tired so it could be wrong)
4 000 ft at 100 ft/min > 40 minutes
Check out the brains! Top of the class for sure.
@@ralphvanthoff *Matt Parker has entered the chat*
I'd be interested in a video on the aerodynamics of high speed flight. The insight on the blanket of air around the control surfaces which prevents a pilot from recovering was interesting.
9:45 That's why pilots are carefull not to aproach the coffin corner in the first place
U2 pilots: (chuckles) *I'm in danger*
lol
I never learned about the coffin corner in my commercial ground school. Glad it was finally explained to me.
More detailed video coming!
If a pilot finds themselves in coffin corner, how do they escape from it (without breaking the aircraft, stalling or dying?)
So, you cannot recover from a machdive/machtuck even if you cut the engine thrust to minimum? Does the dive just get steeper and steeper? Scary.
So would that rip the wings off?
Yea captain Joe, bring those high speed aerodynamics videos
Yes, I'd like to see/know how the engineers overcame the mach 1 drag.
Hey Joe loving the video consistency recently. As always providing us this quality educational and entertaining content. Keep it up bro!โ๏ธ๐๐ฝ๐๐พ
The next 12 weeks are set :)
@@flywithcaptainjoe YESSSSS, looking forward to the videos! Youโve been a huge inspiration to me, thank you Captain Joe :))๐๐ฝโ๏ธ
Absolutely fascinating. Joe is incomparable! ๐๐๐ผ
I am sure he will be an excellent captain. He always uses terms Iโve never heard before. I had to watch this twice....
Would the climb take around 40 minutes?
Thanks for this sir! Ive always dreamed of being a pilot (im 9)
6:35 Beautiful engine/wing shot ๐
Great vid one again joe. Keep up the good work buddy๐๐
Bro thanks so much for this vid. I have been asking you for this vid so much. The best yt channel ever
Nice one, Joe! Yes, would love to learn more about high speed aerodynamics! ๐๐ป
... but then again, I'm a sucker for all aeronautical physics ๐
You amaze me every time you post!! Keep up the great work! ๐คโ๏ธ
Thanks for continuing to make awesome content breaking down this stuff that is so much harder to understand when taught for whatever reason. Always learning!
Hey Joe, very glad youโre still in an operational seat, alas my company have retired our 744โs so Iโm seatless at the moment. Keep educating, youโre doing a great job.
Cheat code to avoid a mach dive: have a delta wing.
Video Request - "Power Settings On Aircraft"
If you mean do we apply a particular setting to achieve a speed? Then no, the air is far too fluid also weight and trim changes would prevent that working, however like cruise control in your car our autothrottle system will change power to provide a constant speed/Mach.
The only exception to this is final approach where gear down, flap25, top hat (3 degrees NU) and 1.15 EPR would have you at VREF+5.
MSFS: MAX POWAH!!
TOGA
please !!
B747-400 with RR RB211 G rated at 50,000lbs from after start the engine will settle at Ground idle with the thrust levers closed.
The next setting will be Take off power and this is where a video would help because itโs not as straightforward as it sounds, there are four options to take off power, they are:
1 Rated power, in my case 50,000lbs
2 Assumed temp reduced thrust
3 Derated thrust 1
4 Derated thrust 2
The top two are the ones we use most as we are either going a long way in a heavy aeroplane or we are going for a flight of say 8 hrs or less even if weโre full, then assumed temp thrust reduction is the norm.
The last two are pretty much only used in contaminated conditions so not very often and itโs just to artificially lower the minimum control speeds in the event of an engine failure so that you can either stop with degraded braking performance or get airborne at a lower speed than usual. Because itโs not used very much, some companies ban its use.
Next is Climb power and again 3 options depending on aircraft weight or obstacles in the flight path, they are:
1 Rated CLB power virtually the same as MAX continuous thrust.
2 CLB 1 a fixed reduction from TO power.
3 CLB 2 see above but more.
The rest of the flight will be in speed mode as I said in my earlier comment with CLB mode used for Step climbs that Joe talked about.
During descent a combination of flight idle (higher idle setting than ground idle to reduce spool up times) VS mode or VNAV which combines all of the above owing to it taking note of altitude restrictions on route particularly in terminal areas.
After flap extension (canโt remember how much and canโt be arsed to look it up) approach idle comes into force again to reduce spool up times to almost nothing should you have to use idle to control speed.
After landing it is mandatory to use at least revers idle, again a high idle to avoid compressor stall, as the reverse levers are moved to the idle gate, the reverse shrouds deploy and the REVS display turns green then anything up to Max reverse can be used, there is a detent which we call partial reverse that is approximately half thrust most normally used on shorter or contaminated runways, as speed reduces so should reverse in order to be idle reverse by 80kts.
When the reverse levers are stowed ground idle is back in force until you reach the gate and shut down.
I love when he says, "A good Pilot is Always Learning " ๐
A BIG YES TO THE HIGH SPEED AERODYNMICS VIDEO.........Loads of love from a
Huge Fan
*I was pondering over this question last week...*
I remember the B-58โs causing sonic booms back in the 1960โs. The were designed to go supersonic. I rode a flight years ago that cruised at 41,000 feet. It was CAVU that day. That was some view up there.
Extraordinary looking plane. I wonder if any still preserved. It had to be kept just for art sake.
Cool looking plane.
Sure you where kid
Did you know a commercial 747 and a DC-10 both went supersonic (by accident). No damage was found on the 747, the DC-10 had slight.
@@mccallfrank007 The flight Captain announced our cruising altitude as 41,000 and the flight data on the cabin video screens displayed that number. As I recall the plane was an airbus A-319. 41,000 feet is well below the service ceiling of that plane.
There's always something to learn in this channel. Thank you!
I can confirm the outstanding performance of a B747-400! We started our flight in Frankfurt in December 1997 heading to Bangkok. The route we flew was over Moskow (we booked a flight to Thailand???) through half of Russia reaching a top speed because of the Jet Stream to 1230km/h for really some hours and the pilots ascended then to 43000ft 1500km before arriving to Bangkok. Great experience to fly 13100m above the earth with this speed! I'll always remember this flight! Sadly I don't have any photos from the inflight entertainmaint showing this experience...
Captain Joe Squad!๐ฅ๐ค
Hi Captain Joe! I always love watching your videos, as Iโm a student pilot and I plan to get a degree in aerospace engineering. Even though Iโm at the PPL level I still love to learn about topics more relevant to commercial/ATPL ratings since I think it gives me a better understanding of aviation as a whole and helps my flying. Iโve always been interested in supersonic flight and Iโd love to watch a video about how flight dynamics change In the transonic and supersonic range. Iโve also always wanted a good explanation of why hypersonic and supersonic are referred to separately. Iโve heard that at hypersonic speeds the air along the leading edges of the aircraft can chemically decompose and cause aerodynamic issues but Iโve never understood it well.
Captain Joe,I just love you and the way you explain things
one of your best videos... Perfect ... Happy Fly Captain
Hey captain Joe, I got a video idea, talk about all the lights/callouts related to failures or other emergencies
Probably the most interesting plane in regards to the so called coffin corner is the Lockheed U 2. It can fly at 70,000 feet but, at that height the difference between the never-exceed speed and stall speed is 12 mph or 10 knots. Sounds challenging even before considering you need to wear a spacesuit to fly (and potentially eject) at that altitude.
Yes please! High speed dynamics! Can't wait for a video on that from you!
good ol' Captain Joe with good sound. Finally.
Would love to hear about high speed aircraft, especially how they navigate in spaces that commercial airplanes won't!
The U2 spy plane was one of the plane with the smallest coffin corner less than 10kts, from STALL speed to MMO at cruise altitude.
Thanked Captain Joe..for valuable information about Aeroplanes, to Aeromodelling enthusiasts
You could be the best flight instructor ever.. the way you explain things is awesome .... Yes for aerodynamics videos
I hope one day this legend here will get 4 lines and become a captain. truely deserved but ye, maybe he have to wait a bit more time before that happens
AFAIK Joe attained Captain before when he flew for Airberlin, but he went back to being FO after he went to Cargolux. Man's got about 5k hours on the A320 family though so he's absolutely experienced enough. Company seniority's a bitch, but it is what it is.
Well explained as always :) Thanks for the effort! (PS: The climb took you 40 minutes. 4000ft/100ft/min= 40min)
40 mins. Loved this video, keep it up!

6:43
Rules can't stop me, I climbed to 2,800,000,000 feet in FSX once!
Ha ha. 2,800,000 000 (are you sure that's right....) That's twice the distance of the moon from earth.... 2,800,000,000 ft = 530,303.0303 miles, more than twice the distance of the moon to earth. (The moon is only ~238,855 miles from earth (on average).
In reality, the upper limits of the earth's atmosphere is about 47,520 ft. (that coffin corner thing....).....Unless of course you're Maverick in Top Gun, he'll try anything.
welcome to steam edition
There are some interesting documentaries about the U2 operating very close to coffin corner
Bought the book yesterday- finished taking notes and scheduled immediate steps. Every chapter in the 10 that i have read so far feels realistic to achieve{ planned to read less and implement immediately then start the next 10 }. Thanks Captain. And I have covered around 20 videos - experiencing this one today.
I love to fly .... It is my biggest wishes to fly one day. I always love to learn about plan. I wont sleep if one day i be on board .
Thanks for the update
Waiting for that โhigh speed aerodynamicโ video
Is there a maximum flight level ATC can clear you to? Or as long as you are within the limitations of your plane you can be cleared as high as you'd like?
5:09, (36000 - 32000) /100 = 40 minuts, and keep the good work up, love it.
Your are my inspiration captain Joe.
Me: sees the title *coffin*
My brain: starts playing the coffin meme song
Same
Question: How Concorde manages to overcome MACH still being an airline aircraft
aerodynamics and afterburner
Delta wings and a shockwave adopted outline (sharp wing leading edges, pointy nose etc.)
Another informative video captain Joe, always a pleasure watching and canโt wait for the next
CA Joe Thank you for sharing these valuable info.
Service ceiling of 45,000 feet is pretty impressive for a commercial plane. As most fighter planes have service ceiling of 50,000 feet.
Or 60,000

yes yes ! i do want to learn more about high speed flight - beyond transonic speeds๐
great video , loving your content ๐
Iโm glad I found your channel again.๐
I hoped you would explain hou to get out of the coffin corner. Reduce power to the engines maybe?
I think the best solution is to not even try to approach the coffin corner?๐
@@geofs_yt_pursuer6976 yes off course! But thatโs not the answer to my question is it? He said do not climb because of stall and do not descend because of increasing airspeed. So what do you do?
@@KoenvanderKouwe You descend at a constant speed by reducing thrust accordingly. With an autopilot with autothrottles, it isn't hard to do.
@@TheOwenMajor Thanks Owen
@@TheOwenMajor yeap. controlled descent.
First officer Joe ๐๐
Correct. Def not a captain hence 3 stripes.
Finally someone explaining what a coffin corner is in simple terms.
Awesome video, it's so interesting when you talk about things that you probably won't encounter because if you do, you may not be able to recover. Aerodynamics of high speed flight would be a great video, I'd watch a 3+ hour video about it! Great channel Captain Joe!
HELLO FELLOW EARLY GANG
Aka: subscribers :)
I was actually pretty curious about absolute ceiling and it seems to be 45,000 ft for 747-8. The information on this is really scarce and the only actual mention of absolute ceiling was on doc8643.com/aircraft/B748 , but like you said, I'm not by any means sure if this is an official number or not.
Awesome video Joe! Would love to see a video on weather systems: what you can/cannot fly into. Thanks
Thanks for another great video C.J. Please keep up the excellent work. Be safe. Stay healthy.
4:59 It took you 40 minutes to do the slow continuous climb?....
How was concorde able to operate in such extreme limits
Wing characteristics (delta shape), supersonic engines, afterburners, and being a relatively thin plane all helped it do some amazing things with height and speed.
Wind resistance goes up exponentially as speed increases and in order to fly the speeds that concord needed to fly and still maintain a respectable fuel range, they needed the air to be as thin as possible, hence the high altitudes. The rest of the plane was then designed to fly at those altitudes.
Moving faster means you can fly in thinner air and still get lift.
She is faster rider than anyone

Understood. I take back the term I addressed you with. I thought you mocked the person in need of a job because it sure seemed like it. I guess it's all a huge misunderstanding then. My sincere apologies for that.
3:12 holy shit that window curve made that plane look as it did a brutal jet fighter-like 90 deg pitch vertical climb
The flight envelope of the SR-71 from the original flight manual has been posted online. It's extremely narrow. It is prevented from going supersonic below about 25,000 ft. due to aerodynamic stress. On the other hand is prevented from GOING SUBSONIC above 40,000 ft, and can't exceed Mach 2 below about 50,000.
We bought my grandpa's casket at the Coffin Corner. They have great prices.
Oooh jealous. I tried to get an authentic CC casket for my grandpa, but in the end it was just a mach-off.
