10 Quirks Of Airbus & Boeing Jets Explained

[@cbaurtx]

One more reason for the A380 having only two thrust reversers: The outer engines can be beyond the runway edge. So dirt and debris could get airborne and be digested by the engines,.

[@therathergoodengineer9285]

But, couldn't A380 carriers fly to FAR shorter RWYS with full reverse thrust on all 4 engines? Imagine an A380 flying to Edinburgh International or something. A 2,500m RWY!

[@motioncompensation1544]

Putting toilets in the cargo hold of the A340 came with some special measures. From the article on this subject by Simple Flying: During the flight, Lufthansa would station a flight attendant in the galley next to the bathrooms to ensure that passengers were taken care of and safely secure in the event of an emergency. The downstairs space has a maximum limit of ten passengers due to having only ten oxygen masks.

[@largol33t1]

I remember that except the brand was Iberia. You should have seen my face when the flight attendant told me to go downstairs to find the bathrooms...

[@a21npilot91]

The design is good although without its own limitations. This lavatories are not that simple to operate and maintain and they require additional safety measures and security compromises. Thomas Cook had also cargohold lavatories on their A330s. It is rather unpopular choice even for Low-Cost carriers like Air Asia X.

[@olfrygt]

It's also an unpopular choice for flight attendants, as they feel completely secluded from almost all interaction and outside input. So much so that Lufthansa removed the downstairs galleys over 5 years ago and now only has lavatories and the crew rests on the lower deck.

[@mikoto7693]

@@olfrygt That makes sense. Due to the nature of people who do pass the interview and pass the training process plus the social nature of the job itself, flight attendants are outgoing, charismatic, extrovert, and friendly. As a result most of them don’t handle long periods of solitude very well.

[@embfixer]

A story I got from a friend of mine about the A380 thrust reverser. When the aircraft first came out a pilot wrote up the #2 thrust reverser for not stowing after deployment. Due to time and parts restraints, the mechanic MEL'd or deferred the repair. He followed the procedures and locked the reverser out. It was later found out that the pilot had written it up as the #2 because it was on the #2 engine, however that is the #1 thrust reverser. The mechanic had locked out the good reverser and left the bad one operational because it only has 2 reversers and 4 engines confusing which one is which. I believe everyone refers to them and L/H and R/H now.

It’s important to say though that the black mask on Airbus aircraft only has an effect on the A350, on the A320 family and the A330 it’s aesthetic

[@asystole_]

I wondered about something similar which the video also didn't answer - I understand the noise comes from the hydraulic system, but *why* is it specific to the A320/A330? Why do no other commercial jets produce the same noise?

[@Oskar0424]

@@asystole_ if I remember right simple flying had a separate 3-4 minute video explaining what that happens. I don't remember if he actually answers your question though :/

[@kuebbisch]

The PTU transfers power between the green (left, connected to #1 engine hydraulic pump) and yellow (right, connected to #2 engine hydraulic pump) hydraulic systems. You hear a sound while the PTU runs, but it starts and stops to maintain about 3000 psi in both systems. In normal operation both engines are running and providing power to both green and yellow hydraulic system, so no hydraulic power is exchanged between the systems via the PTU. But on startup or shutdown with only one engine running you hear the PTU pressurizing the opposite hydraulic system.

[@chicxulub2947]

sounds like rubber rubbing

[@RoBert-ix6ev]

It's simply the sound of the pump driven by hydraulic fluid on the driven side. On the airbus it operates periodically,as you may have heard. On the Boeing, it operates continously, but only WHEN it is reuired to operate, however it's been designed really as a backup feature, and utilised in real need.

I had been a pax on an EAL DC-9 for a power-back and noticed they pushed up the power to almost 65% N1 I'm guessing and quickly pull the throttles back and engage the reversers. The reversers deployed with the engines above idle. Likely tough on the equipment but I did the same thing and we started rolling right away. I made sure the copilot and I had our feet on the floor!

Note that for keeping the same typerating the maker cannot change more than a few % of the cockpit between generations (allowing pilots from older gens to learn new gens stuff without completely retrain on the new planes), the eyebrows windows on the 737 are still there inside the newer versions but are simply blocked outside (the outside skin goes over it, but from the inside of the cockpit you still see the frame that once housed the windows on older gens 737). You can see them at 1:45 in the video

[@thomas9374]

wasn't one reason for the absence of reverse thrust on the outer A380engines, that they are so far out that there ist a high risk that grass and debry from the runywayedges gets blown up?

[@gerardmoran9560]

Indeed.

[@Sterlingjob]

The a380 was designed to not have reversers but were added due to requirements. The rear two wheels on the a380 do not house brake units as to save weight. The outer engines are not over grass.

[@theharper1]

I was surprised that you didn't mention how the 737 Max moved the engines forward and higher to accommodate their size, in addition to the flattened housing. This design change is one of the factors that led to the need for MCAS. I believe the other reason for no reversers on the outer engines of the A380 is that with the size of the wings, the outer engines come close to overhanging the edges of the runway. Using reversers on the outer engines would increase the risk of FOD. I thought that this was actually the main reason why they didn't put reversers on the outer engines, and the weight saving was a bonus. A couple of quirks - the Boeing 717 still has the capability for a tail door like the DC9, but tail doors were phased out after a highjacker used one to escape the aircraft in flight (come on, seriously, is the risk so high?). The most shocking quirk for me was the clamshell reversers on the old 737 engines. I was sitting with a view of the rear of the engine as we approached Penang, getting lower and lower until I thought we'd land on the water, then the runway appeared and the next thing I saw was what seemed like the back of the engine falling off! Then again - wouldn't the classic quirk be the droop-snoot on Concorde?

[@RoyalMela]

Yes, and also the massive size of the outside engines do help with braking. After touchdown and thrust on idle, they work as massive air brakes, like parachutes.

[@theharper1]

@@RoyalMela watch the Blancolirio channel video with the interview with the 777 pilot who had an engine failure on the way to Hawaii. Just keeping the aircraft in the air was extremely difficult due to the drag.

[@mikoto7693]

Yup, the repositioning of the engines for the 737 max both changed both the aerodynamics and the centre of gravity. While I think that it’s not actually called centre of gravity nor does it actually work like that, the analogy is good enough for the purpose of this comment video. The repositioning of the engines gives the 737 max a bit of a sharper upwards pitch than the normal 737s. If the pitch lifting becomes too severe then the 737 max will stall and the engines will flame out. Because Boeing didn’t want their clients to have to spend a lot of time and money training their pilots to fly the max as a new type rating. So that’s partially why MCAS was installed. To make it feel like flying is like a normal 737. But also to counter the steep upward pitch. It would activate and push the nose down to get the aircraft to fly straight, but due to it relying on a single sensor for input when that sensor malfunctioned and sent erroneous information then MCAS would push the nose down and put the plane into a steep dive, But because the pilots hadn’t been told that MCAS even existed nor how to disable it, the nose kept on being pushed down every few seconds and the pilots couldn’t keep up.

[@eudofia]

@@mikoto7693 I still wonder till this date why Boeing was not criminally held responsible for those disasters. Sure, they paid out compensations. But, how can they install a system and didn't tell the airlines and pilots about it? And when that system failed, they were not held responsible. 'Til today, they still maintain that the pilots would have used the manual trim to correct the nosedive. How can a pilot use a tiny wheel in the cockpit to counteract a powerful electric motor at the tail of the plane? Impossible.

One quirk I noticed while flying 747-400s specifically, was the shuddering right at the point of rotation and lifting off the ground. If you're not used to it, it can be a bit off putting. I hadn't noticed this on any other aircraft, even 747 -8's.

[@gerardmoran9560]

Sadly, I never got to fly the 74. On jets form the 73 to 76 if there's a skipping/tugging sensation at liftoff it's because the pilot has insufficient aileron into the crosswind.

[@iainpurdie6346]

Exactly why I wasn't at all perturbed when the Singapore Airlines 747 I was on, departing Auckland decided to scrape its butt on the tarmac. I put it down to the 'shuddering' referred to.

[@gerardmoran9560]

The B757 had a PTU as well. We usually shut down the #2 engine for taxi in but if we were going to a gate where we would deplane with the 2L door (just ahead of the left wing) we'd shut down the left engine since the jetway would be too close to the engine before it was shutdown. The left engine hydraulics powered the nosewheel steering and the PTU would automatically activate. It didn't sound like a barking dog, but it did sound awful.

[@ATIMELINEOFAVIATION]

Nice review of all these cool facts!

[@josesantizo4432]

B787 and A350 are so beautiful

[@SDGreg]

I always liked with the 757 how you boarded about 1/4 of the way down the fuselage instead of in the front of the aircraft. This allows those seated in 1st class or the first couple of rows of economy plus to not have a constant stream of passengers going past you getting to the back of the aircraft. I think it makes disembarking or loading a bit faster.

[@psuberville]

It is nice, but at the same time, when you purchase a first class seat (Say, 1A) and disembark in a foreign country, you get to immigration and discover that half the aircraft is already standing in line. If you purchase a FC ticket, you'd like to be first out the door. The seconds you gain disembarking can mean an hour standing in line!

[@arinjayurs378]

My favorite quirk was the 2 thrust reversers on the a380 I thought that all four would have the thrust reversers because of its huge mass and weight

[@RoyalMela]

Also ingestion on foreign objects comes a big risk if the outside engines also had one. Dirt and debris might fly up in the air and get ingested into engines, since they are close or sometimes over the runway. But, the outside engines do help braking even without reverse thrust. Shut them off and they work like a huge parachute.

[@markvolpe2305]

So in order for it to work correctly, I'm assuming the pilot's put the outer 2 engines at idle speed while the inner 2 will reverse thrust?

[@mel816]

This might be a rumor, but it's said that during the design phase Airbus originally wanted to eliminate thrust reversers for the A380 altogether as they were confident that the braking system was good enough, but they compromised with two when the FAA and EASA insisted it have at least some reverse thrust capability before they can approve the aircraft.

[@magnustan841]

@@markvolpe2305 I believe some A380 engines have no reversers at all and they are meant to be engines 1 and 4 all the time they’re installed on the plane. But If all 4 engines have reversers on them, pilots will put all 4 engines into reverse as they do on all Airbus aircraft by pulling the thrust levers as far back as possible, but the reversers on the outermost 2 engines are electronically disabled.

Six-wheel landing gear on the 777 Coke bottle fuselage of the Lockheed Constellation (Again, not flown on one but saw a flight-ready one in person at the Paris air show once) L1011 Tristar's tailplane has no elevators.

@@herrdrayer The Comet's engines are a beauty, too bad it's completely unfeasible with high bypass engines, the quite flush aerodynamic windows were really ahead of their time as well (and nose, it's really interesting how the newest jets from Airbus and Boeing look so similar in nose shape). The 727s also have air stairs at the back, leading straight to the cabin tho, pretty interesting. You might have seen that already, but most Embraer planes have a similar yoke to the Concorde, I've seen some forum posts that some pilots prefer that in ergonomics, no idea which one is better tho as I don't fly.

[@jaymzx0]

Speaking of quirky Airbus noises, the 'blowing across a coke bottle' sound an A320 makes as it's on final approach is interesting. It's caused by the air blowing over the 'fuel over-pressure cavities' on the bottom on the wing. It usually happens around 160kt. I live under an ILS vector for a big airport and hear it several times per day. I guess there are vortex generators being installed in some jets to eliminate the sound, but honestly I think it sounds really cool. Also, the 'Airbus buzz' created by some Airbus engines at takeoff. It sounds like a chainsaw in the cabin if you're near or forward of the wings. The fan blades at full power are spinning fast enough that their tips are exceeding the speed of sound, so they create mini shockwaves and because the blades are so numerous, make a buzzing sound. When the pilots pull back from full take off thrust, the sound diminishes.

[@makecba]

the buzz only happens, as far as I know, on V2500 powered a320s

[@robertspruce734]

One really quirky thing was the BEA Trident 3 aircraft, I worked for BEA back in the 60's and we took delivery of the Trident 3 after a number of mods and stretches to the T1 &T2. When we tried testing the T3 in hot and high conditions in Madrid we found that it could not take off with such lower air density, so, we went back to Hawker Siddely and they mounted a rocket engine in the tail to assist with takeoff thrust, it was actually a Rolls-Royce RB162, a tiny turbo-jet. It fixed the problem, but when engaged in the takeoff roll, as a passenger you got a real thump in the back as it kicked in! Some people got quite concerned and we got quite a few written complaints!

My favorite thing about the 787 is that those shitboxes don't fly where i live.

[@markusjuenemann]

please more of that!

[@viktorhedlund8655]

I was on a A330-243 a few weeks ago which also hade the downstairs lavatories. Made me think that joining the mile high club must be really easy on such a jet on a night flight

[@rinotilde2699]

I didn't know it was called barking dog sound but I knew it was just the hydraulics. I've heard it so many times and I'm used to it haha.

[@chromebomb]

I like Quirks and features

[@josephisaac2060]

Another quirk I noticed was the super quick rotation of 757's. Flying out of St. Thomas on a 757 the time from engine rev up to leaving the ground was a quick 25 seconds. Not sure if that had to do with the possible shortened runway in St. Thomas or due to the thrust of the 757 itself.

[@TomcatAL200]

The captain I've spent the last month flying with has a lot of 75 time and he says it's due to the relatively high thrust to weight of the aircraft.

[@AndreySloan_is_a_cnut]

Both of the above. Airlines normally perform reduced thrust takeoffs, which reduce wear and tear on the engines. Most aircraft have more thrust than is necessary for takeoffs at less than maximum weights on long runways. The performance is calculated to ensure there are adequate safety margins (all of the considerations which go into that would be a lengthy discussion in itself), and the power is set to achieve the required performance, but less than maximum. Typically the aircraft must do at least one full thrust takeoff a month, in part to validate that the engines are capable of achieving maximum performance. Maintenance tracks when these “Max Blast” (as some used to call them) takeoffs are performed, and when one is required this will be communicated to the crew (usually well in advance of the due date, as crews may not want to do one at a particular airport, for instance due to noise considerations). They will often choose to perform these at airports where higher performance is required, such as those at hight elevations or with short runways. St. Thomas certainly isn’t high elevation, and it’s runway is moderate length (7,000 feet - assuming a portion wasn’t closed for construction), so while maximum performance likely wouldn’t be required, it is always the option of the crew to utilize maximum power should they feel the need exists (which could occur for a variety of reasons - runway contamination, potential wind shear, or even an inoperative thrust reverser). All of that said, as Tomcat said, the B-757 has an exceptionally high thrust to weight ratio for an airliner, so even at reduced thrust, it tends to get up and go more enthusiastically than other airliners (it also has eight wheels with really good brakes, so it will also stop quickly when required) - it was one of my favorite aircraft to fly.

The masking on the windows to help prevent delaminating which was happing on the Airbus windows. Also why Boeing started to get rid of their “eyebrow” windows less windows less maintenance.

[@spongebubatz]

The paint around the windows has nothing to do with delamination, it helps to cope with temperature differences. It only has a use on the A350 though as it has a curved windshield and is a carbon composite built aircraft, on aircraft like the A330neo is has no purpose

[@discodavid26]

One quirky thing I loved was I once flew to Thailand on a double decked airbus (not sure what type/model) I was only in standard class I believe but I was right at the back off the top deck with a window seat with only a staircase behind me too my left and my row off seats on the opposite side off the aisle … but on my right I had the window but due to the curve off the plane wall below my window I had a lovely open topped storage unit that only our two seats could access and that had almost as much space as the standard overhead compartment which we also had .… not only was it a lovely touch meaning I didn’t have to get up and down so much I also had a bit extra leg room … if only for my right leg🤣… but on so a long flight having that and almost double the hand luggage space was a big help!

[@luk0z4de97]

The a380 is the only fully double decked jet airliner in the world so you will have been on one of those.

[@pauldickerson3686]

It always feels funny when we do the takeoff roll with an airplane that has sat cold overnight. The tires get a flat spot and out of round a bit so it may go Bang bang bang bang bang as the tires get back to round. It can be like cruising over speed bumps

[@BomberMilan99]

the 737 classic has even more flattened engine cases compared to the next generation

[@RoyalMela]

Next generation engines have engines mounted higher on the wing. That is why T-CAS was adapted because the point of thrust and balance after that was different.

[@HellStr82]

Yes...and it crashes more often. But hey..Muricans must make their dollars

[@12345fowler]

I always assumed the eybrow windows were used for astronomical navgation back in the time. You could use your sextant and point it to some stars.

I toured Boeing’s factory once. When I did, they were just attaching the wings to the first 787

largers engines needed for higher bypass ratio, not necessarily larger turbines. Also the turbines power the fans rather than the other way around

[@skippynj1979]

The eye brow windows was for using the sextant.. not visual aid in the airport environment while maneuvers.

And the 777x retains the screwdriver tailcone... even as the 737 MAX adopts Boeing's newest tailcone design

At least the 777 and 777x are FBW...

At first I was like "barking dog noise wtf is he talking about?" Then I heard it and recognized it immediately lol

[@Blank00]

The reason the 737NG nacelle will need a redesign has nothing to do with a flat bottom, as proven by the fact that the round nacelle for PW 777s will also need to be redesigned. The main reason why those nacelles will need to be redesigned is because they were designed and entered service in the 1990s, and safety standards back then are different than they are today. It's like the XV20 Toyota Camry: It is sufficient for 1990s standards, but will not pass in today's standards. But the reason why other nacelles of that era, whether from Airbus or from other Boeing models at the time, aren't scrutinized like the 737NG and PW777 is because the fan blades that those other nacelles deal with are tried and true; they were either narrow-chord, or they were made by Rolls Royce, who have been making wide-chord blades since the early 80s. But what sets the 737NG and PW 777 apart is that the fan blades that the nacelles have to deal with were the first time that CFMI and PW designed wide-chord titanium fan-blades, therefore they were more susceptible to failure compared to a narrow-chord blade or a Rolls Royce fan blade. But the reason why the Nacelle was targeted was because a stronger version of the nacelle was simply more possible than a stronger version of CFMI/PW's wide chord fan blade, especially since CFMI and PW are not invested in titanium blades anymore. CFMI is making carbon fiber blades now and PW is making aluminum fan blades now. GE and PW still makes titanium blades for the 767, but they both are the narrow-chord design. Now what about the PW A318, GP A380, and SSJ100? They are newer than the 737NG and 777, therefore the nacelles were subject to stricter standards. If the 737NG and PW777 nacelles are like XV20 Camrys, then PW A318, GP A380, and SSJ100 nacelles are like XV30 and XV40 Camrys.

I had always wondered about the barking dog noise.

[@jimdennis2451]

I like the look of the mast.

[@gooner72]

The A350 doesn't need chevrons because the RR XWB engines are quieter...... End of. I love the shape of the 737 engine casings, it is a unique characteristic as the landing gear is very low and the aircraft sits very low to the ground but it's cool.

On the 777-300ER the closet at door 5 in the center with the door lock. It is not a closet but the entry point for the crew rest which is over the center passenger seats between door 4 and 5. On the 747-400 the crew rest module is behind door 5 in the galley area on the right side of the plane.
