Thales' Instrument Landing System (ILS) 420 and distance measuring equipment DME415 has begun operating at Frankfurt International Airport's 07R Runway.

The ILS system will assist the airport to attain an independent parallel approach on the southern and the new northwest runway at all times.

Commissioning of new system brings the total ILS420/DME415 at the Fraport-operated airport to eight.

Runway Northwest has been operating with four Thales ILS/DME systems since October 2011, a number which has has now been doubled.

As Runway Northwest is restricted to precision approaches only, the additional installation of ILS systems will ensure permanent operation by creating enough redundancy at each end of the runway.

"The ILS system will assist the airport to attain an independent parallel approach on the southern and the new northwest runway at all times."

Thales uses an interlocking concept that will enable one of the ILS systems to always be in operational mode, while all others stay in standby, ensuring complete efficiency in case one of the ILS systems fails, Thales said.

The company is also planning further developments, which include increasing glide slope, allowing higher approaches and reducing noise on the approach region.

The ILS system, when incorporated with distance measuring equipment (DME), will enable safer landings by assisting pilots with reliable and accurate landing information, mainly in reduced visibility conditions.

Featuring a ground beacon and interrogator-receiver, DME will offer pilots information related to the distance between the aircraft and ground station, while operating in a frequency range of 1,000MHz.

Frankfurt international airport reported a 4.6% rise in its passenger traffic to 5.6 million in August 2012, when compared to the same month in 2011.
