Hi All,

I was looking at a few images of Airbus A340. In some of them i found something bulging on the head.

Can you have a look at the above image. That thing above the alphabet "G" in "KINGFISHER".

What is the purpose of that?

Sorry if it has already been posted here b4.

Likely a satellite antenna for TV entertainment system. Could also be GPS.

Could it be some kind of radar system?

I think it's to do with mobile phone usage and internet usage when airborne, IIRC.

This is a SATCOM antenna, it can be used for several purposes.
