No. we are not all blind feeling up an elephant.

The 747 family is the fastest, cruising around Mach .86. And didn't we just do this topic?

the 747 is the fastest at cruise speed
the MD-11 has a higher max speed
and i belive that the older jets did fly at mach .90-.92

I beg to differ. The MD-11 is slower than the 747. It even says so here http://www.airliners.net/info

And even the CV-990 could not quite catch the 747SP.

The Tu-154 with a max cruising speed of 975km/h is a lot faster than the 747-400, but slower than the 747SP.

Are there any -50 DC-8's still tooling around.

One of them broke the sound barrier during predelivery testing for Air Canada many many moons ago.

Can we count the Citation X in this discussion also?

I think since some fractional and charter operators (hence a commercial aircraft) fly the Citation X we can safely count that in, and I believe it will take first place with its Mach .92 cruise...I wonder what Mmo is on the X?

As explored in the Citation X thread though, IAS is not a completely relevant figure since Mach speed varies with altitude AND IAS.

Absolutely it could.

The CV-900 cruised well above M0.9

USAF Hummer,
Mc (the cruise Mach) is an operational cruise Mach, while Mmo is the design cruise Mach. On the Citation X the Mmo and Mc are both the same, Mach 0.92 above 30,650 ft. Below that altitude the Vmo is 350 KCAS.
The Md (Mach dive speed) on the Citation X is Mach 0.99. This is to meet the 0.07 Mach increment between Mmo and Md for flutter clearance and upset maneuver certification.
During the flight flutter testing and envelope testing the Citation X broke Mach 1. It did it the first time on September 26, 1994. A T-38 was used as the chase aircraft.

OK, Clear this one up please. I flew DFW-MIA last month and according to the in flight display, we were cruising mot of the flight at a ground speed of about 610 mph! I guess the pilot really wanted to get to MIA in a hurry. Is this reading accurate? Relevant?

Thanks,
Sam

You said the GROUND speed was 610 mph. Since he was flying eastbound, he could have had a 130 mph tail wind, which means his AIRSPEED would have been 480 mph.

Pilots don't fly based on ground speed, the airplane only "knows" airspeed.

Stale stuff you lot! The Citation X is the fastest. It was discussed earlier.

Never argue with idiots. They will bring you down to their level, and beat you with experience.

Actually it was a DC-8-40 for Canadian Pacific (entered service as CF-CPF).

And ill agree that the 747SP is the fastest airliner in service today. Current production aircraft, the 747-400 is probably the fastest, though Airbus seems convinced the A380 will be faster than the 744 in some of its media releases.



Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety.
