Point Of The One Window On The 777F

Sat May 09, 2009 8:54 pm

I have noticed in a few pics that behind the wind there is a single window on the 777F, what is the point of that.
it can be seen here

Don't know for sure, but my guess is it would allow the pilots to climb and crawl back there and have a visual look at the flaps etc. should they suspect damage or the instruments have issues.

Yeah there is usually one window on freighters for maintenance to view the wing. You don't really notice it ever until you know it's there. Now whenever I look at a freighter aircraft, it just pops out at me.

I was looking at other pictures of the 777F and it doesn't appear to have a window on the other side. I could be wrong, maybe I'm just not noticing it, but wouldn't they put them on both sides to view the wings?

Maybe its a crew rest area? Had a similar thought today when I noticed a few windows on the upper deck of a 747-400ERF.

You want to be able to look out/in before you open the door

Hmm good point. I don't see it on the other side either looking at some AF pics. When you look at pics of a 727, 737, 747, 757, 767, A300 and A310 you can see windows on both sides. Don't know why it wouldn't be on the 777.

AS's 737-400 freighter has it on both sides for maintenance purposes. If you look at pics of other freighters...the window is not on an overwing exit door. So I don't think that's the only reason. This FX MD-11 is a good example of it not being strategically on a door.

It is actually right next to the door. But, I agree, it is to be able to check for clearance before opening the door, especially from the inside.

You're correct. The window is there so a person inside the airplane can observe the location of the cargo loader prior to opening the cargo door.

A few questions for anyone that may know the answers. Sorry if they are off topic

a. Would it be standard operating procedure for a person to be inside the upper cargo bay with the cargo door closed, or would this happen only in very rare and unusual circumstances?

b. Is it conceivable that the main-deck cargo door could be used as an alternate emergency egress of last resort for the cockpit crew? Is it possible to open the main deck cargo door from inside (at least wide enough for human passage) without hydraulic / electric power?

(Edited to reword the questions)

Happens all of the time. Freight makes an excellent bed. Go back, find a soft, flat pallet, and go to sleep (bring a bottle of Oxygen with you just in case.)

Not really. The door controls on the MD-11 are only available by opening the L1 door partially, and you need to have electric as well as hydraulic power to get her open. You'd be better served jumping out the flight deck window, or going through the hell hole if possible.

I have wondered why the main deck cargo door was designed aft of the wing on the 777F. Most freighters, with the exception of the 747 (which has a nose door on some models), have their main deck cargo doors fore of the wing. Was it done for balance purposes?

I presume:

Yes, so they can load it fore to aft quickly. Just so it doesn't tip on it's tail. If the door was in front they'd have to load it by moving each pallet "just enough" so it doesn't tip, weight would have to be kept in front of the CG.

Disclaimer I don't actually load freighters  Smile
oh boy, here we go!!!

Maybe just the lack of physical room to get the ground equipment into that position.
