Stig Shift #21 (Aircraft Maintenance Adventures) 

Opened RU-vid with hope of your new video and guess what ❤😊

Your neighborhood Bus driving colleague here. Just to expand on what you said about feedback on the stick at 21:58 ish, since I know some gamers especially will make some assumptions regarding "force feedback", there's no feedback at all when it comes to flight forces, it just feels like hydraulic damper tension, or a much more heavily damped version of a gaming joystick. Air, ground, fast, slow, doesn't matter. It's always the same feeling. And honestly, it does actually feel very video-gamey, personally I don't mind it and to an extent I prefer it. It's so much less of a work out from what I came from, which were Embraers (145/175). Those were a real workout in a crosswind, especially in the 145 since the elevators are completely manual and cable operated just like in a freaking Cessna, and the controls are really heavy despite them being small planes, especially the 145 (which is still probably my favorite jet to fly, with the bus close behind). But landing the bus in gusty or crosswind conditions is takes so much less effort. I will say though, I don't like how some guys "churn butter" as they say with the joystick, for those pilots that tend to over-control things, it seems to make it worse for them. I see this a LOT with many Airbus youtube pilot "iNfLuEnCeRs" and as a former check airman it drives me nuts. But I digress. With the Airbus (and any plane really) less control = more control. Smooth, minute and precise inputs, no need to go to the stops even in the gustiest conditions. I maybe use 25% of the available stick travel on any given flight, you really don't need much more usually, and they get exponentially more firm much further out from that point to discourage over-controlling. A handful of pilots I've flown with (usually old timers coming from Boeings and about to retire) say they don't like how they can't "feel" what the plane is doing. I don't miss it, and planes I've flown that don't have fly by wire, but that have hydraulically boosted controls still feel pretty artificial to me so I think their point is moot. It's also nice to not have a yoke bouncing around in turbulence. Maybe it's because I'm from the Nintendo and Flight Simulator generation, but the Airbus joystick is by far my favorite way to fly a plane.

8:20 for anyone wondering what it does: EGPWS (enhanced ground proximity Warning system) operates in 5 modes total. The mode important here is Mode 4 more specific Mode 4b. EGPWS Mode 4 is "Unsafe terrain clearance when not in the landing configuration" and it issues a warning (caution level) should the aircraft be not fully configured and descend below 245ftRA, whereas 4a is for flaps down and gear up, 4b is gear down but flaps not down and on newer aircraft there is a 4c which is active during takeoff triggers when insufficient terrain clearance and either landing gear up or flaps not down. Back to topic: Obviously, it wouldn't be very helpful to receive a "too low flaps" warning when you have planned a Flap 3 Landing for the remaining ~250ft constantly. So Landing Flap 3 inhibits this very warning by disabling only EGPWS Mode 4b and only then when the flaps are in position 3, while while keeping Mode 4a active, which is quite important. If the flaps are in position two, one, or up you will still be issued Mode 4b warnings. (This is where Flap Mode comes into play, this one disables Mode 4b for good, so only use that when you cannot extend the flaps for whatever reason!) Now, some might say "but I selected Flap 3 in the MCDU" That is correct but this is only for performance calculation purposes, such as Vapp, Vls, vref, etc and the configuration check on the Landing Memo. EGPWS is a completely independent system and not connected in any way to the MCDU. So in fewer words: The Landing Flap 3 button indicates to the EGPWS that the plane isn't in a flap full config on purpose and there's no need to be worried if the flaps are only in config 3 at 245ftRA. As to the question, what happens if the inbound crew forgets to turn it off after arrival and swapped out for a new outbound crew: Nothing really. The cockpit preparation in an airbus is literally "see any white lights on the overhead? turn them off!" So the new outbound crew wouldn't be able to forget to turn it back off. 1:04:37 time to change the paper :'D

Stig your pretty spot on with the reasoning of Flaps 3 vs full. At my company now we almost always use flaps full unless there's an potential for wind shear. Having flaps 3 allows us to carry more energy into the landing in case we needed it for the wind shear escape maneuver. Keep the content coming man! I learn so much about my fleet from watching your videos, we pilots dont get to see many of the things you show on here! Thanks!

I love the amazing airplane mechanic and stig shift @stig aviation keep up the great content and amazing work rock on man

You’re a nerd just like me when it comes to airliners. Love it Stig, keep it coming so I can learn more.

Ooh, a rare Thursday upload! Hey, I think the people watching love aviation and all want your job, so a little redundant information is no problem for us! We just want to tag along and look at all the cool aviation tech. Every bird is beautiful and each one is different from each other. We want to see it all!

Perfect timing!! Yay! A new Stig Shift!! Woohoo!!

The best part of the week with the latest Stig adventures. No apologies needed for repeating yourself! I could listen all day. Cheers

Wow Stig, thank you. Your videos are just getting better and better, mesmerising, in fact. So informative and detailed. Please, please, please don't ever stop making these brilliant, captivating videos 🙏🏻. I'm not being hyperbolic, and I'm sure I can speak for many people when I say you really are the best aviation channel on RU-vid.

Stig don’t worry about the rerun factor. It helps us amateur maintenance fans ride with you.

Thanks you for this weeks Stig Adventure. Your knowledge and ability to articulate it so well each week is impressive. I like the music as it is so mesmerizing like ASMR.

STIG your channel is growing. Almost 70k subscribers. Before you know it you'll have 100k. We love you stig, a true guardian angel of aviation

I heard a story about one of the classic 737s, I believe it was the 200 series. For some reason, the aircraft was ridiculously underpowered. The -100s had the JT8D-7 engines which put out about 14,000 lbs of thrust. Not nearly enough. The -200 was a little better using the -9 which put out an additional 1000 lbs on top of that but they were still a bit of a pig. On short field takeoffs, pilots became intimately familiar with a technique known as bleeds off takeoff. What this did was it kept the bleed air that was used for air conditioning and pressurization in the engines to be used as thrust. So, the APU had to remain running through rotation which required some complex adjustmens to the bleed systems on both the engines and the APU to avoid causing damage. This was especially prevalent during hot weather and short runways. The downside was if pilots forgot to readjust the bleeds to normal after takeoff, they'd get a rubble jungle in the back! Whoops

As a lifelong aviation enthusiast I really enjoy your insights and perspective. Thank you for making these videos!

Always waiting for your videos to drop

Great video quality

Hey Stig, thanks so much for your informative videos. I am just starting my journey to become a pilot, and your videos really help me understand more about the planes and their components. Thank you so much for inspiring me to work in the aviation field!

love your videos, thank you for sharing...

Excellent rendition of various 😅 aircraft. I don't where to start on asking questions . I m an old C 141 mechanic 1970s through 80s. These planes were built-in 1961. Some still around. They are modifying from guages to electronics. C 5 &17 , KC1_35 are still in use. Upgrades for old pilots is a transition and some do not prefer it but others adjust easily. Keep up your wonderful widespread knowledge teaching all of us. What no cars today? Thanks.

Love your work sir. Amazing content!

Thanks Stig, you are doing great work... I'm really enjoying it. I feel we are there with you. Such as an adventurous job..

Nice Video especially where you explained the feed back of the side and the yoke

Awesome push back video and explanation. 👏👏👏

Stig, you pass so much information for everyone. I think it's better that you do repeat yourself in your videos. I appreciate it and I'm sure others do also. Thanks for helping everyone stay safe.

I recently found your channel, and I love seeing this point of view on aircraft maintenance. I'm currently in college, getting my A&P license, and this helps me see how line maintenance operates. Thank you for all the wonderful explanations and tips. It also helps me learn new things I never knew about aircraft.

Oh, Stig! I’ve learned a new meaning for WOW! Wowweeee, that was cool. Learned a few new things, proving that old dogs can learn new tricks. Thank you, so very much. Take care and be safe.

Heck yeah, i love learning from your videos! if you can keep posting!

Another great Stig class.

Absolutely Love the channel!!!!! Thank You for taking the time to make these videos!!!!!

Great video as always ..keep enlightening with your aviation knowledge

I actually find the refreshers great, aircraft are all very complex and it's hard for a layperson to remember everything. Keep up the good work, man.

Stig, I was an appliance technician for 38 years. I went from a totally mechanical guy to an electronics technicians at the end of my career when I retired. You’re obviously an old school-electronically savvy guy now. I totally enjoy your videos because you are a step by step guy like me. Keep wrenching and producing videos. Outstanding.👊🏼

Stig love the videos I can't get enough of the technical info keep up the fantastic work 🛩

Stig, you never have to feel bad about being redundant, redundancy is what keeps planes in the air, and we all need a little refresher. At the end of the day, I love listening to you, being educated by you, and being shown all these marvelous things by you. I also feel that this episode was especially special, because you shown us a few new things, and did some unique things as well. Hanging out with you is the highlight of my week, thank you from the bottom of my heart, for being so amazing, never forget the magic that is you. ♥

been into avions for decades, your video production quality on visuals, audio and commentary is second to none!!! I have learnt so much more than ever before and it's all because of you and this video. THANK YOU. I am now, you fan and subscriber :)

Love your chilled out nature Stig(with your calming music ). Your humour and of course insights great fun. Always look forward to your videos.

Im an aviation geek. Love your vids...you can repeat yourself all you want.😁🤣✈✈✈

Well hey Stig! Opened RU-vid this Friday night here, and this was just the cherry on top for a great evening! Thank you, keep them coming and I’ll keep learning😉❤

Stig, you have made me get into aviation again and I am currently saving up for my pilot training. Thank you!

You the best stig 👍

Stig, you’re spot on with description of Flap 3 usage of the airbus 👍

such great videos! your job is fascinating. thank you for keeping the aircraft we fly in ship-shape and for sharing these great videos, as always :)

thanks for your videos. i work for the same company different city. I am constantly learning new stuff by watching your videos.

That story behind the Helios Airways flight sends a chill up my spine every time i read or hear about it. It's almost harrowing how that plane flew itself for several hours until it finally ran out of fuel.

Aviation and Engineering from a different perspective. I love this Channel❤ Thank You, Stig 👏

Thanx for allowing us to fly with you. PS-the more technical you get the better!! For me anyway.

Good work Stig.....always learn from your video.....a must watch.....Thank You!!!......Old A&P

Repeat away Stig, redundancy is the backbone of Air Safety is it not? Mb.

Another fantastic Stig Shift! This is definitely the highlight of my week by far. Love the explanations - even the repeated ones! Also nice to see the lighter mornings and blue skies 😎

That British Airways 777 in the beginning has a wonderful livery. So great to have another video to enjoy...

Great video content as always. I love the amount of care you take into maintaining every airplane and taking the time to explain things to us no matter how small or mundane. Have you ever thought of putting together a video of a “sights & sounds”? Meaning a video that just has the airport sounds and visuals as airplanes roll in or go by or as you guys are working on them? It makes it feel like we are there with the sights and sounds of the tarmac.

I love your channel so much. Im a huge av geek and your channel delivers

I love your videos man! Came across it randomly and I’m glad I did. I’m a little nervous since I have a long flight in a 737 MAX soon, and the news has me a little paranoid. But if we have people like you who are knowledgeable and diligent then I trust the aircraft.

I watch your videos from Bolivia. I work as AMT in te Avro RJ-85, but it's amazing to know about many airplanes that you work!! Incredible videos, go ahead!!! 💪🏻⚙️✈️

Love your videos, Stig.

Loved watching the pushback! Nice work by the driver!

I looked into the Air Helios flight 522 disaster a couple years ago. That one flight attendant was a true hero.

Thank you for taking us kids through the candy store. :)

Stig! Love the video man, coming from corporate MX seeing big planes like this is always cool to watch.

I like the way you regularly give the throttles a whack. Love your enthusiasm too👍

Yes, another Stig Shift! I am wondering, clear air turbulence is becoming increasingly common and getting bumpier these days. I'm curious if the aviation industry is readying itself for these turbulent times. Awesome videos, Stig! Keep up the excellent work!

I love this channel with all my heart, keep it up my man

Stig! Never apologize for repeating information brother! Your video's are some of the best out there purely because of your wealth of knowledge and the fantastic way you explain everything! Keep it up man 🤟

thanks A&P , lov to listen you saying something again and again coz its necessary not to forget a real things , plz keep repeating things for us, i love to here some thing my old scool boss always told us on Ramp, seams like we all A&P have same language even if we all are working 10000 miles aways , thanks again for sharing ur job

Thanks Stig. That was epic I learned a lot👍

Well, it's 3.50 am here and I was just on my way to bed. Now I'm most definitely not!!

Thanx again for sharing. It’s been fun

Do different manufacturers engines use different spec oils or is one enough? Tell us more!

The knowledge on here is beautiful, what a fabulous following you have on here stig. Oh, I have serious tool belt envy 😂👍

Love your content

Felt so familiar seeing that SAS RSE A350. I was so lucky to be jumpseating both start and landing from Copenhagen to Tokyo last year. Had no idea as my boss had setup the surprise with his friend who happened to be flying that day. The best thing ive ever experienced.

AWESOME TECH STUFF!

The intro with that 777 was epic :) You kinda get the scale of that beast.

The camera you use is super clear mate. Fantastic video again.

another week another great video

Glad to be back! keep it up

We deserved this video to end the busy work week 😊 them 777s are huge!

I love these vids!

As a some one in A&P school I really love watching your videos and see what I learn in the real world, keep it up!

29:00 iirc, the same pilot that crashed Crossair 3597 was training a F/O in, i believe, a Saab 340. He told the F/O, "if you pull the gear up on the ground it wont go up" and he got the F/O to pull the lever up. The gear, did in fact, go up. The Saab was written off.

Thanks for showing the video on how the window shades work on the 787

You did just fine explaining the flaps. Basically increasing drag and lift ( with added power) with each increment of flaps. Used primarily for TO , approach and landing. Decreased airspeed by using flaps allowing pilot to achieve proper approach and landing speeds. Crude explanation but you did well, buddy!

Ohhh Stig, as always lovely video. In my opinion you can do 3h videos, time is flying when watching your videos. Just had my first turbine lesson in my flight school and it so helpful and nice to see everything in real life. Keep up the good work! See ya soon in the air :)

Keep talking, we're listening, don't worry about repeating your self, still found it very interesting 👍.

Hello Stig. I am a new subscriber to your channel, after seeimg just two videos. I may sound little melancholic now, but I am happy for you and your job, because that's what I've always wanted to do for a living, but never did. I am enjoying every minute of your videos, your narration, your positive mood. Thank You for that! Your videos are like a treat for me👏🏻 Regards, Marcel from Slovakia.

This is always a weekly treat!

@StigAviation Man your videos are great! even though i have the ecsact same job but on another continent(i work at AMS). I still love watching your videos when they come out, and its also really interesting to see the differences in the way another airlines handles theyre maintenance even though i work line aswell!

Camber and chord. Slats and flaps increase camber and chord, which increases lift and drag, which is necessary to lower stall speed upon approach. The 727 is an excellent example. Triple slotted flaps and leading edge slats.

hey stig, im a huge aviation enthusiast and i love the ptu(barking dog) on the older airbus, its funny when im on one and the passengers that dont know about it always say poor dog or where is the dog lol. blue skies stig!!!

I like your videos they're really good

Watching your new video here while I'm flying from KATL to EGLL in MSFS

Anothe great video Stig. Not sure if you noticed but as the nose of the British Airways A380 came into view I spotted not one but two Air New Zealand 777's and at the end of your video as the 787 taxied in there was a plane flying overhead with a vapour trail behind it.

You are the best dude, i wish to had a job and type of work like you do i have a bachelor in MIS, but my mentality are locked about airline jobs. All the best to you and keep it up 👍 🙏🥳

Woohoo, new video. Thank you !

Glad i found your channel 💙

Stig! Thanks a lot for your videos. I'm 4th year student in university in Russia, studying aircraft maintenance We don't have much practice and the lectures are pretty outdated, but your videos really help to see what it's all really about! I'm huge fun of you! I have already worked on An-2 and L-410 during my practices, and this year I'll work on a320 family in Ural Airlines, your videos really help Just honestly appreciate your work, man

You've made my morning :)

About to fly on a British airways triple 7 today 👍🏻

I recently flew from dfw to Orlando on American our plane was incoming from sanfrancisco I couldn't help but think that maybe you worked on the plane before it took off and that it was thoroughly checked! I got to sit right in front of the engines on a A321 and boy do they make some cool noise at full power! First time I've flown in 15 years what a treat!
