The danger with using GPS as a primary approach aid is that someone (at the moment the Americans) has ultimate control of the signal and can turn it off at their whim with no notice leaving every aircraft in the pooh!

MLS won’t really come over here proper until Galileo/EGNOS is completed. Thats Europes GPS satellite network.

MLS is a fantastically good system but if the Americans are prepared to give up their ability to control GPS transmittal and means for preventing jamming are found then GPS approaches will become the way ahead as they need little or no ground installation.

And a 737 with the same nose ring.

A B757 with ring on nose.

BA used to install it’s own instruments in the cockpits, so this might be related.

Yes, it wasn’t just the 737 fleet.

I’m sure I’ve seen BA 757’s with the same nose rings ?

Originally the strange nose markings on BA aircraft was for ground observation to track accuracy while testing MLS (microwave landing system) approach installations. Whether they are still doing it or not I have no idea but I can find out from my BA 737 Captain brother.
