What Are Those Two Lumps In The 777 Cockpit?

Wed Aug 17, 2005 7:57 am

Been wondering for a while and done some searches, and a bit embarrassed to ask... but what are those two "lumps" at either side of the throttle on the 777 central panel? To the right of the flap lever on the F/O side, left of the trim/pitch levers on the capt. side.

They're the back sides of trackballs for input into the FMC and whatnot.

I had a really good link for a bunch of the functions that it performs, but I can't find it offhand. If I do, I'll be sure to come back and post it.

Hope at least that much helps a bit.
We can agree to disagree.

I don't normally send guesses in reply to questions here but I can't find a genuine answer.

So, from the realms of pure speculation how about "coffee cup deterrents"?

Assumably there is some reason for needing the space under the console from the bottom of the keyboards towards the camera position. If the top of this was flat, the temptation to balance drink cups would be fallen into by someone and that could be a tad expensive if liquid entered the keyboard should a cup be upset.

As I said, pure speculation, particularly as I can't remember seeing them on other Boeing cockpits.

Any offers of something more sensible?

That's right. They're like mousepads on a laptop but for the FMC. I think I learned that off the same site you're talking about, but I can't remember what it is. They control the pointer and cursor for the FMC screens much like a mouse does for a normal computer.

Hope this helps.  Big grin

Hi,

Thats the rear of the trackpads that control the cursor for use on the ECL (Electronic Checklist) ACARS and CPDLC. They are not used for the FMS.

Ours are not trackballs but pads similiar to those on Apple and IBM laptops. I'm not sure if trackballs are an option, if so I wish we'd opted for them.

What is SCARS, CPDLC, and FMS stand for? and what do they do? Sorry... I'm still learning... Thanks!!!

The devices are called CCDs or Cursor Control Devices. They all for selecting data which is displayed on the Multi-Function Displays. The data can be from Maintenance Pages, Checklists, Communications such as CPDLC (Controller-Pilot Data Comm System - allows flight crews to communicate with ATC via data instead of voice) and ACARS (Not SCARS, suspect a typo).



FMS stands for Flight Managament System, and I this info is accessed thru the CDU(s).

You said pads on IBM laptops. Don't let a true IBMer hear you. Those hockey rinks were added to the T Series from the T30 due to overwhelming customer demand. The proper way to control a(n IBM) laptop is to turn off that abomination and use the TrackPoint (red joystick) as god intended.

Thanks for all the information guys! Definitely learn a lot in this forum.

I see that A380 also has this feature, what other planes has this installed as a standard equipment?

The CCD is fantastic, and it is a great function for us to have. it takes a little while to get used to the 'mousepad' and the cursor, but once you do, it's great and we are the envy of the other fleets for having it.

Those Cursor Control Devices must have been an attractive option for the Italian Airforce. As you can see they have them in their Boeing KC-767A (767-2EY/ER) refueling tankers.

The Embraer 170 and 190 familys use the CCD. In this picture you can see the Capt. using it to check his Flight Control Page.

Hello Fokker Lover.

Yeah, the very first thought that came to my mind too was ... "Those are the pilots!"

Somehow I managed to keep myself from posting that. I don't know how ... it's a funny thought.  Silly

Anyways, I've used a Lap-Top computer with one of those "Hockey Rink" type of mouse pads where you use your finger tip to move the cursor. I think they're pretty neat, although it felt a bit strange at first ... like my hand was naked!  boggled

Ejazz,

my eyes might be playing tricks on me here, but have the colors of your flag changed recently?
Again, might be me, but as far as my (bad) memory goes, it was an American flag before. Correct?

Aim for the sky!

I'm just so used to the TrackPoint (9 Thinkpads so far) that I really would have to get a Powerbook to abandon it. The control is much more precise IMHO. But all this is a matter of taste and habit.

I said "LUMPS", not Tumors, or Apes...

A good one, Fokker Lover.
