Airfield infrastructure

Thales UK has signed a contract to supply and install a Cat III 420 Instrument Landing System (ILS) and 415 Distance Measuring Equipment (DME) 2 at Liverpool’s John Lennon Airport.

Chris Kelly, head of air traffic services for the Peel Airports Group, said: ‘Liverpool John Lennon Airport is pleased to have selected Thales UK to supply and install a new CAT III ILS/DME system that will replace the current CATII ILS for runway 27.

‘This upgrade continues the airport company’s investment in improvements in its airfield infrastructure and is a part of a programme of work to offer CAT III ILS landing operations at the airport.’

The ILS system provides pilots with information to enable guidance during descent and, with deviation information from a defined approach, path down to and along the runway surface. Similarly, DME systems provide the pilot with distance information between the aircraft and the location of the DME ground equipment.
