Enhanced flight vision system
An Enhanced flight vision system (EFVS, sometimes EVS) is a system for imaging the external world from an aircraft, and to provide an image in which objects can be better detected. In other words, an EFVS is a system to provide an image which is better than unaided human vision. An EFVS includes sensors (one or many) such as a color camera, infrared camera or radar, and typically a display for the pilot, which can be a head-up display or head-down display. An EFVS may be combined with a synthetic vision system to create a combined vision system.
Airport LED transition and multispectral EFVS
EVSs are traditionally based on a Forward looking infrared camera which gives a thermal image of the world, and shows up heat released from airport approach lights. Most airports use incandescent Parabolic aluminized reflector lights,[2] though energy efficiency standards (such as the Energy Independence and Security Act of 2007) have caused some airports to switch to LED lighting, which as a lower thermal signature.
However, since 2007 airports are switching to the more energy efficient LED lighting, which has a lower thermal profile. The new EVS designs are multispectral, to capture both visual light from LED lights and the thermal image of previous EVS generations. Future EVS designs focus on all-weather vision, which can be accomplished by intelligently fusing images and data from cameras operating in visible light, infrared, and millimeter-wave.
Here you go Aviador, Here's what I found after a simple Google search. Looks like its connected to the upgraded LED Lighting systems that the airport has installed and the head ups display on the aircraft.

Just checked and the Aerodrome Manual and it was last updated on September 12th 2017?
So this must have be recent amendment which surely will hopefully be beneficial to all airlines/operators using LBA during low visibility procedures.
I have just been to Elvington and back in G-OCCH and had no problems at all with communications.
That should (hopefully) change when the 8.33kHz channels come in at the end of the month. At the same time, the ATIS message will change to sound less like calling Delivery is optional.
However, you’ll still hear an increased number of requests for clearances on Tower as aircraft which are unable to fly a SID without reference to Polehill VOR/DME, which is out of service for the next few months, are required to ask for an alternative clearance from Tower.
