Hi, everyone. Just a few days ago, I was in Atlanta and in a picture I took of a 767 taking off, I noticed a small panel that stuck out from the fuselage above the windows near the wing. Here is a cropped photo. Does anyone know what this is here for? Thanks for any info you have.

Big version: Width: 416 Height: 314 File size: 28kb
Fuselage panel, N180DN

Looks like a sheet metal repair doubler

I agree, you can see the first layer (thinner layer) next to the skin and the second (thicker layer) on top.

Whatever it is appears on the left side of this aircraft too... and from what I see in the photo database it looks to have been there for a while...

edit: Further checking of the photo database reveals a number of Deltas 767-300s have this feature. I'll guess it's some sort of sat antenna. Perhaps offset to the side of the fuselage to improve the view of the sat during turns.

I checked the photo's too and did see it on several 767-300. I can the doubler and something on top but now I have no idea.

It's a radio antenna. Satcom I believe. We had trouble with them a few years ago , the mounting screws that went into pocket nutplates were too long and pushed the nutplates loose in the fuselage.

Correct, it is a SatCom antenna. Each plane has on on each side. The SatCom satellites are in geosyn orbits over the equator so by putting one on each side there is always one antenna facing the sat while the airplane crosses the North Atlantic. This system is pretty much required to fly these routes now. Planes that are equipped with SatCom and GPS/IRU can fly with less separation on the NATL tracks than those that use the old HF and only IRU set up.

I would have thought the 767-300 came equipped with those out the factory... Was it an option back then?

Interesting configuration for the satcom antenna's. Our fleet has the turtle shell type of satcom antenna's. I never knew there was two different types.

Simple, b/c things change over time and the 767 is old but great technology. Like when most 767s and prolly this 767 came out, datalink was just a twinkle in someones eye. Now Datalink/Satcom are the norm on most any airplane going into non-radar or HF areas.

Just like the FMC's can/have be updated w/ the option of GPS MMR and etc. Things change overtime ALL the time.

Like back in the early days of the 767-200 I think the plane had to be flown in raw data in the terminal area for ILS or NPA(Non-percesion approach). Now only the PNF has to watch RAW data at the FAF on in if the procdure is LSKable or from the IAF if the approach has been built by hand on a NPA only while for ILS both pilots can be in MAP.

Examples like that are the reason this feature was not factory fresh.  

I mean WAAS is the next big thing and only the 787 and A380 can get WAAS/LPV fresh out of the factory and I say that b/c in a few years there will be a lot of new "PATCHS" showing up on airplanes when this stuff starts to really become the norm in commercial aviation.

i'm sure it was BACO installed on the -300's, -200's didn't have it. Probably an option that was ordered.

If you check the photo data base the panel seems to only be on the international airframes.

DL has the turtle shell on 777's and 764's.

The flat plate Satcom antennas are on most 767ER's (not 1701-1708) and were on some former A-310's (035-043) MD-11's and one L-1011

777 came from the OEM with either one sat antenna array on top or a set on each side.
Customer option.
