British Airways has invested £5 million in new advanced technology to reduce the delays and disruption caused by fog and poor visibility at Heathrow Airport.

BA is the first commercial airline to introduce the onboard Microwave Landing System which becomes operational on Wednesday March 25. The system will increase the safe landing rate during periods of low visibility at Heathrow by more than 20 per cent.


This new system has been installed on 29 of the airline's Airbus A320s and A321s with the remaining 12 to be completed by the end of 2009.


Is this the same landing system that they trialed at LGW a few years ago with the 737's


There's flying and then there's flying

Was this the thing that the 757's at LHR tested, and as Lee says the 737's at LGW, the ones with the Black circles on the nose cones?

How does it work? Do they install microwave ovens in the cockpit then you enter the time to landing and it will show you the way in poor visibility and by the time you touchdown you meal is ready as well?

Seriously though, can someone explain how that works?

There is one problem with airbus. Though their products are engineering marvels they lack passion, completely.

Yes, it was the 757 and 737 painted with a black circle on the nose that were used for trialing the system out for a few years now. Glad to finally see it implemented.

All (?) BA's 737s and 757s used to have the black ring on their nose which, during the extended trial period, was used by ATC to identify an aircraft fitted with the MLS system. However now the system is being fitted to othe aircraft in BA's short haul fleet this identification is no longer required and is already disappearing. Here is 752 CPEO 'before' and 'after':

Erm, sorry to sound a bit thick but about 2 months ago on one of my flightdeck rides, the Captain announced that we were performing a microwave landing that day which was a brand new system put in place that past week. Like I say, that was about 2 months ago or something as I lose track of time so why is it all new?


Never give up..

MLS? Seriosuly? The technology has been around for decades but it was mostly used by the military and a few select civilian operators. I'm surprised they rather just stick to the MLS rather than further D-GPS development and get GLS capability. I guess it was just more cost effective at this point in time.

No it was only a couple of aircraft in each fleet.

The idea is not new. There has been a TRIAL installation at LHR for 10 years or more. What is new is that the system is now a production system. The MLS receiver is in the MMR and MLS landings have been carried out by BA Airbuses since Oct last year in regular service. Enough data has now been analysed and the MLS system at LHR is Cat 3B approved. BA is now pushing LGW to install the system. Hopefully now it is in service, other airlines will see the benefits. If everyone had it, there would be much less disruption in Cat 3 weather than there is today.

MLS is in service. Cat 3B GPS is still a dream.

This was certainly not my impression and was not confirmed by checking my own photos. So I checked all photos of BA 752s on the a-net photo data base that were taken in 2008.

All of the current fleet of 11 BA 752s are pictured in the data base with photos taken in 2008 wearing the black ring on their nose. Three are also pictured towards the end of the year without the ring. So in this case I was correct in saying that 'All (?) used to have the black ring on their nose' and my question mark was superfluous.

I also checked all the 735s in the fleet in 2008. 'FA, 'FD, 'FG, 'FH and 'FI are all pictured with the ring while all the pictures of 'FE, 'FF and 'FJ taken in that year do not have the ring. Further checks showed that there are no pictures of 'FE or 'FF in the data base with the ring, but that there are photos of 'FJ taken in 2006 and earlier years when it wore the ring. I also checked out the two 735s that had left the BA fleet by early 2008. Both 'FB and 'FC are pictured wearing the ring in earlier years. So all but two of the BA 735s actually wore the ring.

I have not checked the 733s or the 734s and they may, of course, tell a different story.
