Fastest Commercial Planes At The Moment?

Sat Jan 14, 2012 12:44 am

What are the fastest commercial planes flying now and since the 70s?

Are the trijets faster than the twinjets?

I believe the Citation X (Cessna 750) can go 9.2, normal crusing speeds range from 8.6 to 8.8

As far commercial, carrying pax for airlines, nothing's faster than the 744..as far as I know.

I believe the Convair 880 was one of the fastest commercial aircraft (I believe they were around in the 70s) and obviously the Concorde
Ironically I have never flown a Delta MD-90 :)

A little slower, perhaps, at M0.92. No hypersonic planes yet - :-P

The Gulfstream 6 is touted to be M0.925. Splitting hairs really.

Non biz territory, with current models in the sky, A380 is Mmo 0.89, and I imagine the B744 about the same. I know ECON CRZ for the B744 is M0.855... When I last flew the A380 with EK they were cruising a M0.875. I do not know if that was faster than normal...
A306, A313, A319, A320, A321, A332, A343, A345, A346 A388, AC90, B06, B722, B732, B733, B735, B738, B744, B762, B772, B7

Was my Eagle pilot lying when he told me the CR7 was one of the fastest commercial aircraft? On my ORDDEN flight a month ago he said he'd get it up to .87ish.

I remember the 744 and the 727 as also being particularly fast. With a tailwind I think the 737s can get into the upper .8s also but that is just from flightaware observations. Most of these speed differences are not significant enough to warrant a change in block schedules.

I hope you don't take offense to this, but I do want to point out that this statement is factually incorrect.

Tailwinds or headwinds do not affect a plane's speed in the air in any way, shape or form. Tailwinds or headwinds only affect the measure of "ground speed" - ie: the speed the plane is moving relative to the ground. You could be in a 744 at 0.87 mach, but in a 150 knot headwind - you won't be going very fast relative to the ground.

The discussion is premised upon the maximum airspeed of currently flying commercial planes. As far as I know, the 747 is the fastest currently in service...

It all depends on how fast the airline wishes to fly, and in these days of expensive fuel that's quite often very close to ECON speed. In rough numbers, it goes something like this:

BAe146/RJ85-100: 0.72
B737CL/MD80/CRJ/E-Jets/717: 0.75
B737NG/A320: 0.78
B757: 0.79
B767: 0.80
A330/A340: 0.82
B777/MD11: 0.84
B747: 0.85
A380: 0.86

That's not to say either of the above can't go faster or slower, but given an equal playing field the above is what you'll roughly see.

The CV990 could cruise at .95, and if you really want to a 707/727 can potter about at .88 - but they'd certainly want something for the effort!

I do not believe the 0.87, however the CRJ is one of that fastest aircraft around in the approach configuration, somewhat faster than most aircraft of its size.

But as you said, splitting hairs indeed  

So as far as I know, the fastest one still in activity is, and remains, the Citation X.

Actually there is a very good natured rivalry between Cessna and Gulfstream for the title of fastest Business Jet. They get along because Cessna is a mid-size and Gulfstream is large cabin, so they do not see one another as competition.

It's a little confusing because Cessna makes two different planes: the Citation X, and the Citation TEN. Cessna is waiting for Gulfstream to certify the G650 at Mmo 0.925, then Cessna intends to announce the new Mmo for the Citation TEN (Probably Mm0 0.93)

The Citation TEN has a slightly longer cabin, winglets, and slightly updated and more powerful engines compared to the Citation X.

But I believe the Citation X is still the fastest (Mmo) certified civil aircraft in production today. And that's a mouth full.

Since the Citation X is used for part 135 operations, that makes it a commercial aircraft. (although not a scheduled airline)

I had a type rating for the CJ2 series a few years ago, and I'll always remember my visit at the Cessna's facilities and assembly lines.
A warm welcome from our Cessna's hosts.
Very interesting to see the Citation X line, and the fantastic bare shape of the fuselage. What a plane! It was well worth the visit... I'll always remember a X ship with "speed is life" written on each sides..
Definitely a great memory!

If I understand correctly, it is not that clear cut. While airspeed at given airframe configuration, load and engine settings does not change, most economic speed does change with en-route wind. Basically with headwind you want to go a bit faster, so you end up with less distance in the air. With tailwind, you may want to stay afloat a bit longer at lower speed and lower engine settings to let wind do the job and save some fuel.

Isn't that the type of hyperbole you boast to a group of NFL cheerleaders onboard when you're attempting to get a date? The CRJ-700 isn't exactly a lead sled like a Boeing 737 classic but with an Mmo of .85 it isn't a 747 or an A380 either.

I recall an old corporate pilot recalling the days when he regularly flew straight pipe Lear 25s for a Las Vegas operator. Those old Lear 25Ds looked sexier than heck, made great fighter jet sounds on take-off and even at gross weights climbed like a homesick angel. However, with a wing swept only about 13 degrees at 25% MAC it was an aerodynamic turkey compared to todays Citation X and upcoming Gulfstream 650. A few unscrupulous operators even had a "go-fast" switch that deactivated the .81 Mmo overspeed warning; the Lear had the power to easily cruise at .85 with just a minor amount of aileron tip-buzz.

It worked great until a Lear disappeared over the Caribbean in turbulence and the Feds found out about the "go-fast" switch.

They must have lest pretty close to each other, and ... had ATC assistance getting to the NAT Tracks. As with a difference of M0.03, the difference on an Atlantic crossing would be about 15 minutes at the most. (And probably closer to 10 minutes).

That's true, however the OP isn't talking about 'most economical' speed, but simple, absolute top speed. For that, you just look at the Mmo, and whichever aircraft has the highest number wins.

The 777 has a faster cruise than the competition it has, the A330/340. However, I do not remember people purposely choosing this over the A340/330. But I don't doubt Boeing used that as a marketing scheme.

American Eagle pilots typically argue the CRJ-700 is the fastest aircraft in the AMR fleet besides the 777. The CR7 wears the same engines as the much heavier -900 giving it it's high cruise speed I believe. I've witnessed FL410 and .83 on them.

Yeah all you have to do is pull the CB and turn off the RH Stall switch so you don't get the pusher/puller. I would never go over .78 in the Learjet 25 though, it's just a homebuilt! The buzz is the plane telling you it's about to come apart lol. The wing was very well designed and over built with 7 spars(only 2 go from tip to tip) however the tail is the weak spot of the airplane, only held on by 2 bolts the diameter of your thumb.

Now the old 727 on the other hand...if you can afford it, it will do .90 all day at the right weight and altitude.

He said they were flying almost every time close to MMO which is, if I recall correctly, about M .89, with heavy loud Cost Indexes like CI 400 or 500... Pushing the jumbo up to .88...

Actually on the CV-990, it was the "A" model that was the fastest commical jet of its day (CV-990A). It could go to M.95, but normal cruise was M.91 I believe. It had those GE built CJ805-23 engines, with the fan section in the aft portion of the engine, instead of the front (it was a civilian version of the J-79 engine). But the B-707-120 and B-720 (both non-B models) with JT-3C engines could do M.93. That was due to them being very similar to, but heavier than the KC-135A (which had the same JT-3C {J-57} engines), but the KC-135A had a Mmo of M.95. The "B" models were slower with the JT-3D engines, but took less runway and could climb faster.

Not quite that fast, but in indoc we were told the CR7 is the second fastest aircraft in the AMR fleet (AA and MQ combined) only behind the 777. Chicago always gets mad when we're (in the Embraer) in front of a CRJ because it causes spacing issues. We can go pretty slow with a Vm (flaps up) of about 165/170 knots and they'll have to throw in some slats/flaps to go that slow.

As far as I know the Tu-154 was the second fastest commercial plane until the Concorde resigned.
So I is supposed to be the fastest passenger aircraft now in service. (Wikipedia says M0.88 cruise speed)

I have used the most reliable source ever: an airline in-flight magazine  

In the airline magazines that feature their fleets and have both 747-4 and A380 (SQ / LH) they always have them listed as:
A380 is 0.86 and the 747 at 0.85, all others are slower.

What I have found interesting although I do not recall the speeds is how close a 777 and a 767 are.

On a personal note: One time on a TATL Air France 747, way over a decade ago, hit 0.9 on the projected flight map.

Of course, the reality (thanks Longhauler!) is substantially less sensational....

VS, at certain times of the year, have both a B744 and an A346 daily to LAX. This is one of the longer TATL trips and the difference was never more than 10-12 minutes on average. On a JFK flight the difference is usually more like 6-9 minutes.

So, even assuming there are two flights scheduled to leave at the same time (of which I am aware of none), and that ATC put them on the same NATtrack without holding one on the ground for spacing (which they wouldn't, for obvious reasons) the outcome would more likely be a result of luck than anything else.

Even the B757 ( and also the B767), which cruise at more like M.80, would not take appreciably longer on a TATL trip. All things being equal it would be a few minutes. Throw in all kinds of ATC, routing and airport related variables and it could go either way.

The closest comparison I could find is EWR-LHR, which sees everything from B757-B744. Most days the difference between fastest and slowest is covered by 15 minutes, often less, and not always does the fastest aircraft mean the fastest trip.
So long 701, it was nice knowing you.

Note that QF 11 (SYD-LAX, A380) has a scheduled duration of 13:40, while QF 107 (SYD-LAX, 747-400ER) is 13:35. On the return flight for both, QF 12 (A380) is 15:00, while OF 108 (747-400ER) is 14:55. Not that significant of a difference, but it does suggest that the 747 is faster than the A380. Not like 5 minutes matters on a 13+hour flight!

And on that note, DL and VA's respective 77L and 77W have a scheduled duration of 15:05 on LAX-SYD

Didn't MEL-LAX and LAX-MEL have more of a difference back when they operated some days with a 747 and others with an A380.

So the 737 and 320 are the same?

The B737NG and the A320 series are very close .. .within M0.01, under identical conditions, and with the same cost index.

However, the B737-100/200/300/400/500 are slower. As they cruise around M0.75, vice .79 or so, on the B737NG/A320.

But, all things being equal, the B737 Classics had a different "mission" and can get into and out of runways the B737NG and A320 can only dream of!
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

Wow, i cant believe nobody has mentioned the fact that the DC-8-43 broke the sound barrier in a shallow dive, even prior to the Concorde, which made it the first passenger plane to do so.

Accoarding to wiki, Its max cruising speed was around 575-600mph(depending on variant) at 35,000ft. Not sure what mach that would put it at at cruise or if it was even typically flown that high.

Makes me wonder what ever happened to OS's A330s?

They went to TAP in 2007.

Would that be due more to the fact that the 747 and A380 can take a more direct route while the 777s have to stick closer to land? I don't know how different the routings are between the two aircraft, but that may have something to do with it because the 777 is still a pretty quick plane.

The great circle routing for LAX-SYD doesn't even come close to ETOPS 207 (previous 777 ETOPS certification) restricted area, which is the shaded area on the following map. 777's now have a 330 ETOPS rating, which means they can fly anywhere except for a (relatively) small area over Antarctica.

My question is if a 747 can cruise naturally at 0.85, can, if wanted or tested could it hit Mach 1 without breaking apart? Or would it require Mr Scott to keep her glued together?

I believe that during testing, the 747 did exceed Mach 1 during a dive.

Are the trijets faster than the twinjets?

Generally no.

Isn't the MD-11 especially fast?

It's unusually fast on approach, not particularly in cruise.

Quoting rjm777ual (Reply 33):
I was on flightaware and I saw an Aeroflot Cargo MD-11 going 593 MPH!!!!!

Flightaware shows groundspeed. With high tailwinds, you can easily see over 600 mph.

That's completely different than cruise speeds. Most commercial jets can go supersonic in a dive but none of them (excluding Concorde) are certified to do so.

Yes. Most commercial jets are structurally capable of going that fast in a dive. However, you may experience major controllability issues.

On a BA 772 from EWR to LHR in early March, we exceeded 800MPH groundspeed and made the trip in 4:45.

The trip home a month later was almost 9 hours.
