hi guys, Trent brought to attention about the "spinal hump" thing on the roof of the A300Bs... its somewhere on top the back row of windows... somewhere near the tail fin. u can see it if u take a closer look. it's not seen on a 300-600. does anyone have a clue what's it for?

I don't know. Could you be more specific about the location? If it's directly overhead it may be where the til fin joins the aircraft fuselage. Just above the windows, I don't know.
I've never been in an A300. Sorry.

I'm just looking at a few A300-600 photos now and I see a very small bump a little aft of the No3 door. Is that what you want to know about? If so, I suspect it's something to do with communications/radios.

I am almost certain that these are UHF aerials, used for the aircraft's communication. There are two of these; one on each side of the aft, top portion of the fusalage.

The "Spinal Hump".

Sat Aug 28, 1999 2:40 am

The spinal hump I was referring to Jaemz earlier is shaped like an elongated protrusion. I know what the average UHF aerial "bumps" look like, and this feature on the A300B4 does not look like one of those. To me, it looks like some kind of structure reinforcement for the top of the rear fuselage. To make it easier to translate what I mean, it looks like a long metal rod, about several meters long which is embedded in the rear third of the A300B4. This is funny to me because I thought everyone knew about this feature. This used to be how I would differentiate early A300s to the A310-200 (without the winglets). Just take a close look at some photographs, it really shouldn't be that hard to spot, it's like a long rod-like element on the top of the aircraft starting from the midpoint to the bottom of the tail. Good luck!

Anyone correct me if I am wrong, but I belive these are SATCOM antennas. Different styles for different manufacturers. Locations vary along the crown of the fuselage dependent of the aircraft and already existing equipment.

I'm sure it is either SATCOM or HF or UHF antennae, like at the top of the leading edge of the 707's tail. Is it not on the -600R, then?
