All data taken from the 2001/2002 edition of The International Directory of Civil Aircraft, which a.net uses for its own aircraft data section. All of the numbers, are, of course, in knots, which does vary and isn't actually as good of an indicator as the maximum mach operating speed, but that was available for only a few aircraft. The knots figure should be a good way to compare aircraft, even though altitude and temperature both affect airspeed expressed in knots.
I draw 2 conclusions:
a). Older jets are faster than newer jets due to gas costs.
b). As a plane is stretched, it gets slower.
Flat out max speed:
549 - 727-100/200
545 - 707-120B and 707-320B and 720B
540 - 747SP
538 - 747-300
530 - 747-200B
530 - DC-10-30
509 - 737-100/200
395 - Piaggio P.180 Avanti
Normal/Typical cruise: (a category in the book for some aircraft):
490 - 777-200
482 - 777-300
461 - 767-400ER
442 - CRJ700 and 900
438 - 717-200
437 - MD-90
424 - CRJ100 and 200
Long range/econ cruise:
495 - 727-100
490 - 747-200B, 747-400 (and 747-300 long range cruise)
486 - Tu-154 (486 is econ, 460 is for long range)
485 - 747-300
484 - 707-120B and 720B
483 - L-1011-500
478 - 707-320B and DC-9-10
475 - A340-200/300
473 - MD-11
472 - A300-600R
467 - 727-200
464 - A330-200/300/500
463 - L-1011 (long fuselage)
461 - 767-200
460 - 737-100 and 757-200 and 767-300
459 - A310 and DC-8-70
457 - A300B2-200/400
454 - A319/A320
453 - Fokker 100
447 - A321-100
443 - DC-9-40/50
440 - MD-81/82/83/88
439 - 737-400
438 - MD-87
430 - 737-200/500 and DC-9-30
429 - 737-300
366 - F.28 Fellowship
325 - L-188C Electra
321 - Saab 2000
(Some Russian aircraft had a range of speeds, example 460-485 kts, so I didn?t include them, and a few of the newer craft only had Mach numbers, like the A380 at 0.88 max and 0.85 for long range)

I think the 747 should be at the top of the Normal/Typical Cruise section. I understand it goes at either .85 or .86, and the 777 is .84.

Well, the list was getting really long so I omitted the bizjets for clarity. Besides, these forums are always so heavy iron centric that even a Global Express is hard pressed to attract much interest. But Maiznblu_757, I think your chart records airspeed at a certain altitude, which is why it only shows the Citation X going 475 knots. Ohhh it can go fasterrrr...

Pfft. Mach 0.85. Try "Mach 3+"

Hi,
I have read that the B747SP can reach up to Mach 0.92 (forgot the sources).. But I don't know if it's max cruise speed or normal cruise speed.. Also, md-11 are also very fast, flying at M0.86 at normal.. I am use it's faster than B747-400 (M0.84-85) as I flew on one before in the cockpit and the captain told me that the MD-11 (of swissair) was flying above us at a faster speed. I love the airbus as well but A330/A340 normal cruise speeds are just about M0.78-0.82)

As you said in the first post, knots are a fairly poor indicator of speed. And some of those numbers do not seem right. For example, the 777-300 is actually faster than the 777-200 (.85 compared to .84).

The corp aircraft is missing:
Gulfstream GV -optimum crz M85
Gulfstream GVSP-opt crz M85 but 3.2% more fuel efficient than
the reg GV.
The Citation X max crz is M88 or more.
I did not forget...I just misplaced the thought...

I thought that the 777 numbers were a little strange as well.
The Convairs aren't in the database because no one flies them commercially anymore.
And for the record, the book does say that the Concorde does its thing at 1154 knots.

Lijnden,
You are correct about the CV990.
Vmo...M.97, 581 knots.
Max high speed cruise, M.94, 560 knots.

Look in the earlier Boeing jets, like the 707, the 727, the 737-200, and the 747. Also, the Douglas DC-8 too. The 707 and the DC-8 cruised at Mach 1, The 737-200, the 727, and the 747 all flew faster than 570 miles per hour. The 747 and the 737-200 cruise at 575 mph. The 727 cruises somewhere from 570-575. The newer jetliners like the 757 and 767 cruise at 530 mph typically, as well as the CFM-56 powered 737s. The 777, however, while slower than the 747, 727, 737-200, and 707 and DC-8, has actually altered one of your claims, MD-90. The 777 cruises at 555 mph, almost reclaiming the speed of the 757 and 767's predecessors. Stretching an aircraft I imagine would make it slower, because it increases the weight of the plane. Maybe the Boeing 7E7 will be even faster than the 777.

I actually read somewhere in this forum that the VC-10 is one of the fastest
It was fairly fast - 505 kts max cruise, 478 kts economical cruise (for the Super VC10).
Thrust,
The 707 and the DC-8 cruised at Mach 1
Says who?
The trouble with all these numbers is that you can't convert from Mach numbers to knots, since the conversion varies with altitude - which is not given.

Thrust,
None of the airliners you mentioned are supersonic, nor are your relative speeds correct. Below are typical cruise speeds for the aircraft you mentioned. Not sure of the mach numbers for the 707, 727, and DC-8, but I'd bet money the 747 is faster.

737-700s routinely cruise at .81. It is more common to see them above .8 rather than around .77-.78, that's where the MD-80s and older 737s cruise.

I can't vouch for a specific airlines operating policy, but Boeing states clearly, both on their website and through a number of other sources, that the 737NGs cruise at .785. Older models cruise at .74 to .75.
I've also had this verified by pilots at US Airways and Southwest.

No offense to anyone so far...but my lovely CE-150 pulls a nice 120 kts. on full RPM in a nice tailwind!
