Is there a reason why on some their 737s and I think all of the their 757s there is a black ring around the nose.

Thanks in advance.

No. There was one B757 with MLS equipement and that had a black and white quarters painted on the radome. Its gone now. I think it was IKK?

I understood that the black ring is a distinctive marking that allowed air traffic controllers to identify those BA aircraft operating into LHR and LGW that are equipped with an experimental microwave landing system.
