Cyrrus Manages Radar Engineering Project Successfully

30 October 2008

To support the Robin Hood Doncaster Sheffield (RHADS) airspace change, effective from 28 Aug 08, an engineering solution was required to facilitate the Radar Approach Control service for RHADS at Liverpool John Lennon Airport (LJLA).  A robust communications service was essential between the two airports that would enable the transfer of critical radar data and radio signals from RHADS to LJLA; remote control of radio and Remote Status Monitoring of all equipment associated with the radar approach function was also a requirement. Cyrrus were brought in to oversee the design, installation and management of the project and worked with the airport in taking their general requirements and producing a set of technical requirements from which a specification and design could be produced.  The project was successfully completed within the required timescales and budget.

Airspace Change Proposal Success

21 June 2008
Cyrrus Ltd has successfully managed another major Airspace Change Proposal (ACP) request with the UK CAA’s Directorate of Airspace Policy (DAP) on behalf of Robin Hood Airport, Doncaster Sheffield (RHADS).  The ACP resulted from the rapid increase in the number of commercial flights operating at the UK’s newest International Airport and the potential for traffic conflictions posed by the high level of other air activity in the busy unregulated airspace around the airport. DAP considered there was sufficient justification in the proposal for the introduction of Controlled (Class D) Airspace to afford airlines additional protection on their descent from, and climb into, the UK’s en-route airways system.

It should be recognised, however, that the establishment of a large volume of Controlled Airspace does affect other airspace users, such as the MoD, General Aviation operators and recreational users.  Consequently, it is obligatory to design airspace that is the minimum necessary to achieve the aim which in this case was to offer sufficient protection to the commercial (airline) traffic, whilst causing the least inconvenience to other airspace users.  A large scale consultation exercise (as required by CAP 725) had to be conducted, which included aviation and non-aviation consultees; in all, over 260 individuals and/or organisations were consulted.  Most noteworthy was that the proposal did not attract a single adverse comment from an environmental perspective.  Altogether, the ACP process has taken 4 years to complete.  During this time Cyrrus staff have reviewed and refined the proposal through various iterations to devise safe and robust operational procedures to meet the needs of the majority.     When Manager ATS at RHADS was informed of the award he remarked “Thanks for all your efforts ….. I’m more than happy with the outcome”.

Airspace Change Proposal Success

23 April 2008
Cyrrus Ltd is pleased to announce that it has successfully managed and brought to fruition an Airspace Change Proposal (ACP) request with the UK CAA’s Directorate of Airspace Policy (DAP) on behalf of Norwich International Airport.  The ACP resulted from the introduction of changes to the Norwich Instrument Approach Procedures and relocation of the airport’s holding pattern as a consequence of the impending withdrawal of the ‘NH’ Non-Directional Beacon.

DAP commented that they pleased to note that the ACP was developed and submitted in accordance with the requirements of CAP 725. DAP went on to express satisfaction that the change detailed in the submission was appropriate and that the issue of operational arrangements with those adjacent airfields and airspace users affected by the proposal had been adequately addressed.  Moreover, DAP noted that a suitable response was provided to environmental concerns raised during the sponsor consultation phase. 

The new Norwich procedures have a target implementation date of 3 July 2008 (AIRAC Cycle 7/2008).

As Cyrrus continues to grow, a decision was taken to better serve our customers by re-locating the team to 2 geographical locations, one in the North and one in the South of the country.  This re-location programme has recently been completed and we have moved our headquarters to new facilities in North Yorkshire managed by Martyn Wills.  This new office is located in the Thirsk Business Park - the address and contact details can be found on our Contacts page.

The second regional office is located adjacent to London Stansted Airport and is managed by Richard Ingless - the address and contact details can be found on our Contacts page.  The existing office at Robin Hood Airport Doncaster Sheffield (RHADS) will remain for the time being but is likely to reduce in importance in the future.  Any changes in contact details will be notified to our clients via this website.

Oxford NDB/DME Project Completed And Commissioned

1 February 2008
Cyrrus Ltd has just completed the successful handover of a turn-key project to provide a new NDB/DME facility at Oxford Airport.  This major project was completed on time and within budget, to the satisfaction of the UK CAA (Safety Regulation Group) and the Airports’ Management.

This standalone project arose from the successful completion of a major package of work project-managed by Cyrrus for Oxford Airport that first commenced in August 2005.  The main project included widening the runway by 7m and then resurfacing and re-marking the entire enhanced runway as a Code 2 instrument facility.  Completely new AGL, including Cat I approach lighting to support the installation of a new ILS on runway 19, new IRVR and met recording facilities together with a fibre optic data communications system were also part of the project.  Cyrrus also undertook the detailed design, and oversaw the installation, of many of these individual sub-projects.  During the overall project roll-out, the Oxford Airport Management decide that Cyrrus would be best placed to undertake the 2 separate roles of Airport Engineering Authorities for the ILS and Data Communications system and the overall Airport Engineering Management function as well.  Cyrrus Ltd has successfully assimilated these roles into their responsibilities without major difficulties and now provides these essential and accountable functions in an extremely cost-effective fashion.

Airspace Change at Robin Hood Airport Doncaster Sheffield (RHADS)

30 January 2008
Cyrrus is currently assisting RHADS in the progression of their airspace change proposal with the UK CAA (DAP) to establish controlled airspace at this developing UK regional airport.  This is the third UK airspace change process (ACP) that Cyrrus has undertaken in the last 4 years.  The Company was responsible for the design, development of the consultation material, co-ordination of the consultation process, integration of the environmental impact assessment and assisting the airport management in discussions with a myriad of interested parties and organisations.  The formal application will be made to the CAA in mid-March and outcome of the application should be announced in April 2008.  It is envisaged that the revised airspace arrangements will enhance safety and efficiency in the provision of ATS in the local area.

Peel Group Limited - Contract Award

In parallel with the airspace change proposal that Cyrrus is managing for Robin Hood Airport Doncaster Sheffield (RHADS), the Cyrrus Technical Director (Radar and Radar Systems) had been asked to make an evaluation of the current communications systems and provide a report on what enhancements would be necessary to enable the ACP to be implemented.  A technical requirement, based on the detailed preparation work conducted on behalf of RHADS during November and December 2007, was produced which requires the creation of a dual redundant VHF and UHF communications facility for RHADS operated from Liverpool John Lennon Airport. This includes the provision of Voice Switching, Radio Transceivers, Data Recorders, Emergency power, ATC consoles and racking, land line services and associated communications infrastructure. The deployment of this system requires professional project management and system engineering skills to achieve a timely and successful outcome, minimising risk and maximising certainty of delivery.
