Dubai "Follow the greens"
Can someone perhaps enlighten me as to how the system in Dubai works, as it became clear today that it is not done in the traditional way.
It seems that the greens are illuminated for a short distance ahead of the aircraft and as you taxy, the greens progressively light up one by one. Even when taxying at different speeds, the system seems to keep up with the pace of the aircraft, with a similar number of greens always being lit ahead. I am guessing the lighting system is dependent on a SMR input?
Does the lighting system tie in with the EFPS for the allocated taxy route, or is it run separately?

Hi Emma,
In Dubai, Follow the Greens system delivered is a fully automated system in compliance with ICAO Doc 9830. It progressively lights up lights ahead of aircraft for about 200m, turns off as the once the aircraft passes based on the surveillance input and a seperation of 100m is maintained between aircrafts. Delivered system is operated by Integrated Controller Working Position and has been integrated leveraging an ATM grade Integration Engine with following systems:
1. Airfield Lighting Control & Monitoring System
2. Electronic Flight Progress Strip Systems
3. Advanced Surface Movement Guidance Control System (SMR + MLAT)
4. Visual Docking Guidance System
5. NAVAIDS like ILS/DME
6. Flight Data Processing System
7. At the Glass Video Recording System
8. ATC grade Video Surveillance System
9. Surface Manager (SMAN)
10. Pre Departure Sequencer
11. MET/AWOS
12. Airport Operations Database
System delivers following functionality:
1. Routing - Manual, Semi-automative and Fully Automatic
2. Guidance - Taxiway guidance, Runway Entry/Access and Runway Exit
3. Control - Runway Conflicts, Taxiway Conformance & Seperation
4. Planning - Calculation of TSAT/TTOT
System has been operational for a while and have proven beneficial for all stakeholders:
1. Capacity: +5ATMs in LVO
2. $800k worth of lighting energy cost savings
3. Reduced impact on ATC mental workload: 57% in VMC and about 70% in LVO
4. Improved situational awareness: 22% in VMC and 52% in LVO
5. 7500 Mt Carbon emission savings
6. Less radio congestion
Hope above helps.

Still very much a trial, if the NOTAMs are anything to be believed 
A0269/17 NOTAMR A1825/16
Q) OMAE/QXXXX/IV/NBO/A/000/999/2515N05522E005
A) OMDB B) 1702251700 C) 1705231600
D) DLY BTN 1100-1600
E) NEW AIRFIELD LGT FLW THE GREENS BEING USED.FLW ATC INSTRUCTIONS.
WILL ADZ ON ATIS IF FLW THE GREENS ARE IN USE.
PILOT STILL RESPONSIBLE FOR WING TIP CLR WHEN FLW GREEN CL LGT.
REF AIC 06/2014.

Depends on your definition of SA I guess.
The greens doesn't subsitute following up your position on the ground chart. It does however lead you on to the proper taxiway once you vacate the runway. From there on everything is a little less stressful and you've got time to check in detail where the greens are taking you.

It was tongue in cheek.

Raghu only trying to help.No place on here for a long retired Heathrow controller to be making comments about someone for whom English probably isn't their first language.

Yes, we use manually switched FTG at LHR during darkness and low vis. I do worry that, certainly for non-familiar crews, there is an aspect of 'follow the magenta(green) line' and so the crews may be less likely to be aware of exactly where they are
On a serious note, it's a great system. LHR is pretty straight forward and it's easy to find your way around. It's just that moment as you expedite off the runway, before you get the ground chart up, not knowing if you're going left or right, outer or inner, that can be a bit panicky. The greens really help.

That's why you have Brake to Vacate, Airport Navigation Functionality and an F/O who can beam the charts to your screen the moment you vacate the runway!
Technology is good sometimes, not just on the ground
As for what Raghu said, follow the greens in DXB at your peril........

Follow the Greens - Background Information and Videos
Check this out, think about it, think about language problems resulting in 'strange' aircrew performance. IMO this system is designed to help both ATC and aircrew to act safe and efficient in a professional environment. May need some mindchange but ATCOs should be smart enough to identify a tool that helps to make work safer
"...at your peril..." is absolutely not adequate, there are profesionals working at DXB !
