B733 & B734 Cruise Speed

I was wondering if any of you pilots out there who fly the 733 and/or 734 could tell me what your normal cruise speed is. I've been on a 738 and when the flight information was on the moving map, it showed the cruise speed as Mach 0.81. Can the 733 and 734 cruise at or near 0.78? In Boeing's information it says typical cruise is 0.74 but I find that to seem pretty slow.

Thanks for your help.

We plan our 73's at M.74 but I've seen them flown .78 or .79 before.

Remember the NG has a different wing. As a result the cruise speed and ceiling are both considerably higher.

Most 733/734 operators fly at M.74-76.

While the 737NG is often operated M.78-80 range.

Also the 737NG can operate at higher cruise altitudes (41,000ft) versus older 737 series (37,000ft).

The speed we use for cruise for 737400 type is the ECON speed selected from the FMC.There are factors involved for the calculation of the econ speed which varies from operators.(cost index,weight etc).

When I select the ECON on cruise -400 gives M.74.I can also change it by either entering different value on the FMC or changing the cost index.You can also control the speed from the MCP panel.

When I fly the 737-800 the ECON gives M.78 but often we fly M.80.(Thats because my company is a small one and every airplane has other flights after our arrival.If we are in a delay for some reason we try to make it as quick as possible back to base.The difference of extra fuel burn will compansate the loss due to delay)By the way I have never seen a 737-800 flying with M.81 before, anytime I write .81 to the FMC it gives back the message "UNABLE MAX M.80.5"

Thanks guys, that clears up a lot. I know that in the FlightSim world I usually get a comfortable cruise at 0.74 with a medium - heavy weight load while other times with a lighter load, I can easily reach 0.76 with an "economical" fuel burn.

I appreciate your help.

USAirwaysCLT, if you fly the 734 in FS2002 I recommend this add-on: http://www.dreamfleet2000.com/737.html. All the switches work, and so does the FMC. It's a thing of beauty. Pity it's not compatible with FS2004...

Starlionblue:

Thanks for the recommendation, however, I'm using FS2004 and yes, it would be awesome if it worked with 2004.

There is a great alternative for FS2004. But it's a little more expensive. Check out:

Ok, not to turn this into a FS forum (god forbid  Big grin), but PMDG are great too.

Of course, if you have multiple desktops and a lot of money to burn you can always start playing with this. I have tried the 737NG setup and it is total megadrool on twin LCDs + a projection: http://www.projectmagenta.com/
