BA B757s Need Nose Jobs!

Tue Nov 07, 2000 4:16 am

Why do the majority of BA 757s have circles painted on the noses?

I dunno but I don't like it. Doesn't look very nice.

Cheers, B737-700

It is actually an unpainted black ring. I think it is to attract lightening so it does not strike the nose causing damage to the weather radar!

thats a strange theory, is that why most airlines used to paint their noses black right upto the early 90's? the BA noses do look hideous 
.....up there with the best!

If that theory's correct then why's it only on BA B757s,
and why don't all BA B757s have it?

Actually, I think all Boeing radomes have the black ring for lightening protection, but most airlines paint them over.
I think there was a question in either Airliners or Airways about this very subject recently.

As a result of your reply to my reply (??!), I searched for the article in question, and actually found it!

The subject of the "bumblebee" rings comes up in Airliners No. 61 (Jan-Feb 200 issue), page 12. It seems that these rings are a special anti-static conductive paint. The reason for this is to prevent p-static buildup on the airframe.

The reason that I recalled lightning protection is that these rings are connected to the lightning diverters built into the radome. I apologize for my faulty memory.

P-static or precipitation static charges interfere with radio reception and transmission on an aircraft.

Hope this helps.
