EICAS message SPEED CONFIG

Recommended Posts

Dumb question as I'm still learning this plane.  But I sometimes see the yellow EICAS message "SPEED CONFIG".

I searched through the entire FCOM and even the Internet but couldn't find anything on this message.  Anyone have any idea where I can find it spelled out in the book?

Thanks.

If I just jump in the plane and tell it short fuel and empty weight and take off without setting anything up.  Simply a test flight by hand, nothing at all sophisticated.

I have been doing the tutorial but sometimes I just want to take off for a quick flight around the airport without any FMS setup.

It's just that I can't find info on that EICAS message anywhere.  Even the internet, I spent a while looking, no info on it.  I'd just like to know what it means depsite doing what I'm doing, there must be a reason for it, just don't know what is means.

Thanks.

Hi Jack

I can't find that particular message either, but it (or they -- could be two separate messages) is telling you that you have not set up the FMC and other systems properly.  Not too surprising since you haven't set up the FMC and other systems properly!  Why not learn to fly it the way it is supposed to be flown?  Frankly, I'm surprised you are not seeing a whole bunch of EICAS messages.

I understand what you're saying completely.  I work 767's as an avionics tech in real life, I know I should be setting it up correctly, I'm just wondering about this one particular message.  There's absolutely no information anywhere on it yet it's right there in yellow on my EICAS.

You must have access to RW 767 manuals.  Is it in there?  Also I'm guessing there are really two messages, "speed"= not enough information to calculate VSpeeds and/or other speeds (climb, cruise, flap deployment max speeds, etc.) and "Config" = a general warning that the aircraft is not configured for flight.

I no longer work full time for medical reasons so I can't access them.

And it isn't two separate messages, it's one, yellow SPEED CONFIG.

My feeling about this is that it may be a bug, but one that  isn't important.  I would be much more concerned if you did configure it properly and still got a strange EICAS message, or if you neglected to configure something and did not receive a message (e.g. not turning on a fuel pump for a tank with fuel, or having an X-Feed closed that should be open and not seeing any warning message). 

Sorry about your medical issue.

It's not in the QRH I have (but I haven't looked in the official PMDG one).

My guess, however, is that it is probably connected to the fact that you haven't completed the CDU preflight procedure with weights and V speeds etc, which the aeroplane requires to, for instance, generate the flap bugs on the speedtape.

I looked in the PMDG one, the one with like 1200+ pages, nothing.  I'm sure this is what it is but I'd like to know why it wasn't in the huge document.  I'm not complaining about it, just very curious from a former avionics tech's standpoint.  I've never come across this message.

Thanks.

Literally not much to go on here, but we're already claiming 'bug' without actually tracking things down.

Nice...

I'm not making an issue about a bug, just pointing out  that if the plane is pretty much not configured it wouldn't be surprising if some unexpected message popped up, or that PMDG didn't notice that that could happen.  I'm assuming that you test with the plane being configured as it should be, with then some anomalies added, rather than starting from some unknown mostly non-configured state.  I have no way of knowing in just what state the aircraft is when the message pops up. 

Why get all bent out of shape when I said "it may be a bug, but one that isn't important"?  PMDG can't be expected to test every conceivable combination of aircraft settings.

I am curious to know, along with the O.P., why the message can't be found in the manuals though.

Isn't  Speed Config when the two pitot systems disagree in the airspeed and the airplanes automated system can't trim the elevator STAB correctly?

I will send a screenshot when I get home.

I doubt it's a bug but I am very curious as to what it means.

Here's how I get it.

Plane in runway, engines running, use CDU, Short Fuel, no Payload.

Flaps to 25 or 30.  Message.  Take off and retract gear and flaps.  Message still in view.

Land, message in view.

I do know this isn't correct but I occasionally like to test things without a full flight plan.

I don't have time to check the manuals, but I think 25 and 30 are not takeoff settings.  Can you select 25 or 30 for a takeoff flaps setting on the takeoff page, and are you able to set V Speeds?  Are all weights entered on the Performance page?

Hi,

I confirm normal takeoff flaps settings on the B744 are 10 and 20. Flaps 25 and 30 are not used for takeoff.

How do you get takeoff speeds for the flaps 25 and 30? I never tried but I'm not even sure that you enter them in the takeoff perf page and get takeoff speeds.

I know they're not and Mike, thanks but I mentioned that all i do in the CDU is swt fuel and payload nothing else.

This is not correct I know but all im really doing is testing P3Dv4's swttings not making a proper flight.

And in real life on 767's when i would do pitot tests as you describe we would not see that message

Does this happen with a flaps 10 or 20 take-off? I've never attempted a flaps 25 or 30 take-off, as that isn't standard at all.

Yeah, test it out and see what happens. You shouldn't be trying to take off with flaps 25 or 30 anyhow, as this isn't authorized, and I seriously doubt the plane was tested this way. But one thing I need clarification about.

When you say "use CDU", what exactly do you do.

I have FSX.  I set up a 747 similar to yours, as best I can do from the information you gave.  I am not seeing that message.  I can't get V  Speeds since I haven't entered a runway or flight plan.  I can enter flaps 10 or flaps 20 on the takeoff page, can't enter 25, 30, or any other setting (no surprise there).  I get  warnings for the two yaw dampers until I align the inertial navigation system.

I suggest you file a ticket w/ PMDG and ask them what that message means and where to find it in the documentation.

First, the plane is already running, IRS's aligned.

Bring up the CDU so it's a 2D

Then LSK FS Actions

Fuel short flight 

Then on the CDU Payload empty

No other actions in the CDU at all.

FD's off

Advance throttles and take off and go around and land. 

And yes Mike, I completely and 100% understand this is not the proper procedure but as I keep indicating, this is only to test P3D's settings while the 747 is in the air.

I do make proper flights, last night from KORD to KMSP and it was fine.

I know this is incorrect, but like I've said several times, I'm just curious.  This isn't a bug or a show stopper, it's simply curiousity as I can't find it anywhere.

Looks like I did exactly the same, except that I had to start engines, turn on various pumps, and align IRSs.  I did not fly but you are seeing the message on the ground too.  I'm not seeing it, but using FSX Steam.  I have the update issued at the same time as the one that went to P3D V4 users.

I just tried what you did and wasn't able to replicate it, either. I'm also running FSX Steam.
