airbus a320 vs boeing 737 safety

Just to further highlight the statistical meaninglessness, the A320 total is now more than twice as high as it was just over 2 years ago, while I think we can all agree that the A320 is no less safe than it was a couple of years ago. under-full-control crashes like controlled flight into terrain (pilot screwups have nothing to do with the airframe, and account for a lot of accidents), weather-related issues that are not pilot screwups (e.g. To allow all cookies click OK. Do card bonuses lead to increased discretionary spending compared to more basic cards? Boeing has a great presentation covering the commercial fleet accident rate from 1959-2012, and just looking at the accident rate graph shows how far commercial air travel has come in cutting their accident rate. 13. Does the Boeing 737 MAX use electro-hydraulic actuators? Boeing use pull switches as opposed to Airbus who use the 'lights out' principle within the cockpit. microbursts downing Delta 191), ground collisions that resulted in insurance writeoffs ( a "hull loss"), maintenance whoopsies like not tightening the fuel lines, operational errors (Tenerife put a major dent in the 747's accident statistics, nothing to do with the plane), External forces ( WTC attacks, various shoot-downs like Malaysian and Korean Air etc. Well, to be fair, the difference between the NGs and the A320 here would be well within the margin of error. How do airplanes maintain separation over large bodies of water? And, in fact, according to your numbers here, it was the other way around as of the end of 2009. Of course, this also means that there are a lot more old 737s to be sold to the aforementioned third-world airlines than A320s. I thought I'd compare the accident rates of these two similar, competing, very successful aircraft. Similarly, the 737 also relies on various technologies and redundancies to improve safety. •Are there that many 40-year old 737s in the hands of incompetent airlines? While the first A320 delivery was in 1988, the vast majority of A320 deliveries have been since 2000 (5,029 A320s out of 6,171 in service were delivered 2000 or later.) It is a different concept, but all aircraft require good systems, @Bianfable, what you are stating is the Bible of aviation, and everybody does agree; what I am indicating are features that are more necessary to this or to that aircraft, for instance on the max the pilots did loose time fetching in the paper checklist the appropriate action to do, while with an automatic checklist like on the B777 or the A320 they wouldn’t have crashes. One additional consideration is that the Airbus 320 is quieter than the Boeing 737 in the flight deck. Was Aloha Airlines Flight 243 (the Sunshine Roof flight) a design flaw, maintenance not fixing it properly, operations not grounding it for maintenace etc. ). Thanks for watching and please subscribe for more great videos!! Why did postal voting favour Joe Biden so much? Of course, these planes have flown more miles, so the difference in fatalities per passenger-mile is most likely lower than 5x. Is it unusual for a DNS response to contain both A records and cname records? Until summer 2013, there had been a grand total of zero passenger deaths on a 777 ever (in nearly 20 years of operational history,) then 3 fatal incidents happened within a year (none of which, as far as we know, were actually related to the airframe. and then it gets a lot harder. How is the Ogre's greatclub damage constructed in Pathfinder? Plus I imagine older 737s have mostly been retired". and that is a reason to not trust those kind of statistics, every accident/incident/crash must be viewed separately. I thought I'd compare the accident rates of these two similar, competing, very successful aircraft. Airbus A320 Neo vs Boeing 73 7 MAX. Why does the landing gear control have 3 positions (up/down/off) on Boeing 737-800? This is a really rare event, and statistic over such low rate are not relevant. Are you saying that Airbus pilots make fewer screwups, avoid weather, don't hit things on the ground, have more careful groundcrew & engineers, get better ATC instructions and are less favoured by terrorists? Naturally, there are plenty of variants of each to choose from, and if To subscribe to this RSS feed, copy and paste this URL into your RSS reader. etc. For one, the early 737s had a design flaw which allowed the rudder to reach a hard-over position, and get stuck there. But thankfully, there are very few accidents for each type per year, so the statistical base is too low for a meaningful comparison. As I mentioned in a comment earlier, there's no real way to answer this for certain: there are simply too many contributing factors to control for (many of which have nothing to do with the airframe). The Boeing 737 is a bit smaller with a 148″ fuselage and only 139″ in the cabin. 737 A320 Introduced 1968 1988 Number Built 8104 6171 Accidents/Incidents 329 60 Hull Loss Accidents 154 23 Fatalities 4287 782. Is the 737NG hydraulically controlled or electronically controlled? The 8,104 737s have, on average, flown many times more cycles than the 6,171 A320s? • The Boeing 777, Airbus A319 and ERJ- 145 have all recorded no fatal accidents to passengers or passenger fatalities. /sarcasm. Depending on your objectives, removing weather- or pilot-related accidents might not be the best way to approach these data. Based on their respective Wikipedia Orders and Deliveries numbers by year, the average fleet age of the 737 is a little over 16 years while the average age of A320s is only about 8.5 years. Altogether, the A321neo has a maximum capacity of 240, which trumps the MAX 10’s offering. A: No, there is no difference in the retraction procedure between Airbus and Boeing airplanes. But they address the same market, why would their usage differ so markedly? So, what is the answer? Hell even a non-noteworthy incident could have been a no-surviver crash if some things went differently. They might not all be 40 years old, but, yes, there are tons of older 737s that were sold off to third-world airlines and/or airlines that simply operate in more dangerous areas. rev 2021.1.11.38289, The best answers are voted up and rise to the top, Aviation Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. At first glance, the design of the flight decks for Airbus and Boeing aircraft which are currently in production are visually quite similar. Questions - Boeing 737 vs. Airbus A320 advantages - Hi all, If you were a boeing 737 salesman, how would you sell the Boeing 737-800 in comparison to By September 2018, there were 7,251 A320 family ceo aircraft in service versus 6,757 737NGs, while Airbus expected to deliver 3,174 A320neos compared with 2,999 Boeing 737 MAX through 2022. Boeing initially dragged their feet in rectifying this, so it took a number of accidents before this design flaw was corrected. Because many of the world's airlines are wholly or partially government-owned, aircraft procurement decisions are often taken according to political criteria in addition to commercial ones. To have a more meaningful comparison, I would suggest to compare the fatalities per year, so the status in operational procedures can be excluded as a factor. •The 737s have, together, flown many times more passenger-miles than the A320s? There are lots more older less-safe 737s being flown by corner-cutting budget airlines in third-world kleptocracies? Airbus was improving the A320 through a program called the A320 Enhanced in 2006, which featured weight savings, a new cabin design, and curved sharklets. In short, yes. @RedGrittyBrick I knew it existed but Google found it for me (I don't recall my search string, but "Boeing statistical summary of commercial jet airplane accidents" is apparently what it's officially called). •But they address the same market, why would their usage differ so markedly? A lot of the 737 fleet already had flown many cycles before the first A320 ever rolled out of the factory. Though first built in 1963, here we have a quantum leap in safety. Otherwise you can use this tool to manage. +1 for the last part of the answer. Safety. Why aren't 737s or A320s commonly used for transatlantic flights? 8 hours ago, - Why is there the discrepancy reported in the question? The 737 family can be divided into four separate series (or generations), two of which are no longer in production: On the other hand, the A320 family includes only two generations o… Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. The safety of the A320 relies on the automatic checklist like the B777, on the FBW, on the redundancies as a summary on Technology, The safety of the B737 relies on the experienced pilots from generation to generation who know all its qualities but also all its weaknesses. Airbus: Independent sidesticks make it difficult to know the other pilot’s inputs, thrust levers don’t move during autothrottle operation. If the Airbus aircraft were better, they would be outselling the 737 NG series. They include the Airbus A380 and Boeing 747-8 ... the safety of the modern Boeing 737 MAX aircraft has been ... Boeing 747-8, Airbus A350, Bombardier C Series, A340 and the Airbus A320 … It should be noted that the CSeries and A320NEO have only recently started deliveries so the in-service numbers are small. The link actually has the answer. Plus I imagine older 737s have mostly been retired. But you need to consider that many more A-320 were flying at the time than 737 NGs, and if you take that into consideration, the A-320 could well be considered safer even in the time before 2009 - with all caveats, as mentioned above. Are there that many 40-year old 737s in the hands of incompetent airlines? In total, the B737 fleet has about 131,000 aircraft-years of history compared to about 52,800 aircraft-years for the A320. In addition to the average 737 being significantly older (and, thus, having significantly more flight-cycles) than the average A320, you still have to consider that there are 31% more delivered 737s than A320s. Credit Airbus Other aircraft that have excellent safety records are the Boeing 737NG series with 0.08 fatal crashes per one million departures (PMD), the Boeing 767 (0.10), the Airbus A320 series (0.10), the Boeing 777 (0.18), the Boeing 757 (0.20) and the Airbus A330 (0.19).

Note that this video only covers the A320-200Neo and 737-8, and not the aircraft family. Were 3,500 of those fatalities in the first 20 years? Then you will love this! In addition, Airbus’ CE… A 25 September 2009 entry on the AirSafe.com News described the contents of the following video, which lists popular airliner models with the five lowest fatal plane crash rates. Would the advantage against dragon breath weapons granted by dragon scale mail apply to Chimera's dragon head breath attack? But I would expect that the low fatality rate in the early 2000s is more due to the small number of A320s around. My speculation doesn't seem very convincing to me. It's even tricky with first-line carriers. Love Switzerland and the DC-3? - I assume they have not been the subject of edit-war falsification by fanboys of planemakers. Other aircraft that have excellent safety records are the Boeing 737NG series with 0.08 fatal crashes per one million departures (PMD), the Boeing 767 (0.10), the Airbus A320 series (0.10), the Boeing 777 (0.18), the Boeing 757 (0.20) and the Airbus A330 (0.19). Number still in service (outside the U.S.): 412 Sindreu, J. zThere are nine major commercial pure jet aircraft that can claim to be the world’s safest aircraft because they have never recorded a passenger fatality. READ: What does it take to make our top twenty safest airlines? This is a major contributor to the high number of fatalities in the early operational years. The upgraded 737-300/400/500 (Classics) which appeared in 1984 had a crash rate of 0.25, while the 737 NG (New Generation) models which entered service in 1998, have a crash rate of just 0.08. It only takes a minute to sign up. I doubt that which airframe is more safe has really changed since then. Hull loss rate/million departures: 737-1/200: 1.75, 737-3/4/500: 0.52, 737-6/7/8/900: 0.26, A318-A321: 0.26. We will put the A321neo up against the 737 MAX 10 since the latter has the closest amount of seats to the Airbus model.. The initial models had a fatal crash rate of 0.89 PMD. Take a trip to Central and South America. Which jet airliner types have had the fewest accidents per million departures? Is Dirac Delta function necessarily symmetric? Q: Is there any significant difference in fuel burn between the A320 and 737NG family? These numbers are the NG 737 aircraft vs the Airbus aircraft. ), We simply need more accidents to collect statistical data. Retrieved from . ... How Boeing should have responded to the 737 Max safety crisis. The Boeing 737 and Airbus A320 are two of the most popular single-aisle planes flying. A new one should be coming out right about now, and. Take the world’s most successful jet, the Boeing 737, with over 14,300 sold, which was first introduced to service in 1967s. @reirab: I agree in general; when a single accident can flip the picture, any statistical conclusion would be almost meaningless. You would have to plot the accidents against the year to even begin to have something reasonable. The Boeing 737 and Airbus A320 are two of the most popular single-aisle planes flying. As others have pointed out, this should give a more equal basis for a comparison. But if we just compare the 737 NG with the A320, this advantage is reversed, and still the A320 comes out slightly ahead. Raw numbers like this are more-or-less useless. The screens, thrust levers, and various controls and levers are located in similar positions as can be seen when comparing an Airbus 320-200 and Boeing 737-800 flight deck in images below. While I'm not sure that their average use cases are very different for aircraft of the same age, there are far more old 737s than old A320s. How does SQL Server process DELETE WHERE EXISTS (SELECT 1 FROM TABLE)? The 737 is longer and taller than the A320 is, this results in the 737 having a higher lower number of seats when compared to the A320. Why does the Boeing 737 have a pitot tube on the tail? If we want to draw any conclusions, it could be that the A320 is indeed a safer aircraft, but the certainty of this conclusion is very low, being based on a very small number of accidents. Plus I imagine older 737s have mostly been retired. Cookies are very small text files that are stored on your computer when you visit some websites. What does it take to make our top twenty safest airlines. The remaining 3760 fatalities were in earlier models. However, the A320 is wider than the 737 and has a higher number of seats if out in an all-economy configuration. A320 has triple redundancy in systems like AOA and radio altimeter/ autoland vs Boeing double radio altimeter/ autoland and single aoa channel. So, in short, I don't think any one factor explains the difference, but the sum of several factors, most of them being related to age, does explain the difference. Design philosophy and cost savings approach seems more safety oriented on the airbus. Why does Steven Pinker say that “can’t” + “any” is just as much of a double-negative as “can’t” + “no” is in “I can’t get no/any satisfaction”? What kind of horizontal stabilizer does a Boeing 737 have?
