This proposal is for a Permanent change to the notified airspace design, and the change level is TBC.
As part of the national transition to performance-based navigation (PBN), NATS plans to remove from service most of the Doppler VHF Omnidirectional Range (DVOR) network in the UK. The DVOR and Distance Measuring Equipment (DME)
based at Manchester Airport (MCT) will be removed from service as part of this national programme.
The Manchester (ACP-2019-23) Future Airspace Strategy Implementation (FASI) will provide Required Navigation Performance (RNP) approaches, from 7,000ft, to all four runways (Runway 23R, Runway 23L, Runway 05L and Runway
05R). However, until ACP-2019-23 is complete, the CAP1781 process is being used to provide a temporary solution using RNAV substitution. In addition to this temporary solution, temporary contingency procedures are required for use in the
event of ILS unavailability, to ensure operational resilience.
To provide these contingency procedures, it is proposed that RNP Approaches, that provide an extended centreline to the runway end, are established at Manchester Airport. These contingency procedures will replicate the existing ILS final
approach to Runway 05R, Runway 05L and Runway 23R and their use would not result in any change to aircraft tracks over the ground when compared to an ILS approach to the same runway.
Manchester Airport will continue to rely on the ILS for normal operations and the contingency RNP Approach procedures would only be used in the event of failure of the ILS, a Radio Communication Failure by an aircraft, a loss of radar
surveillance, or as otherwise instructed by Air Traffic Control
