Cyrrus - Airport and Air Traffic Consultancy, Management, System Design and Technical Safeguarding

Cyrrus, an independent airport and air traffic consultancy with a wealth of engineering and operational experience, specialises in bringing original, up-to-date solutions to the challenges facing the industry.

The company focuses on air traffic management (ATM) and communications, navigation and surveillance (CNS) programmes. Over the years, Cyrrus has become well-regarded and recognised in a challenging and competitive industry that only accepts the best when it comes to engineering and project management.

Airport project management

Cyrrus, along with its trusted partnership companies, covers full operational processes that can be found in airports. From the early concept stages, right through to the planning, design, construction, evaluation and operation, Cyrrus's ATM project management is systematic and rigorous.

Cyrrus and its partners' project reporting incorporates first-rate assurance and monitoring, which is crucial for transparency and ease of understanding for senior management teams, including earned value analysis (EVA) and delivery of associated metrics.

Cyrrus works along side local management teams to make sure that every project meets the respective operational requirements. The company manages risk, which in turn helps to find further opportunities and benefits, while also providing solutions that comply with regulatory requirements.

Air traffic control system design and engineering management

The Cyrrus team has expertise when it comes to air traffic control (ATC) system design and engineering management, as well as experience working as active military and civil air traffic controllers, air traffic engineers and project managers at domestic and international airports.

Cyrrus employs system design and post-project engineering management requirements to every project that they become involved in. They are not obligated to use any particular supplier, which helps the team to provide the most cost-effective and sensible solutions, and goes some way to shape the company's renowned reputation.

Cyrrus has a deep understanding of primary surveillance radars (PSR) and secondary surveillance radars (SSR), which extends to a large variety of radio-based navigational aids and communication facilities that can be found at airports and ATC centres.

Safeguarding of airport navigation equipment, radios and radar signals

When safeguarding does not take place, it more than likely means a natural decline in the quality and reliability of airport air navigation equipment (AANE) radio and radar signals. Pilots and ATC will be the first to notice problems, such as poor coverage and increased background noise. Cyrrus can assist in safeguarding the technical sites and making these problems a thing of the past.

In the UK, the safety regulation group (SRG) of the civil aviation authority (CAA) publishes technical safeguarding (CAP 670) requirements. The air traffic service (ATS) providers are made responsible to ensure that developments do not impact on the safety of the ATS environment. If standards drop below acceptable levels then the regulating authority can withdraw approval until services have recovered.

Cyruss's technical experts, with extensive knowledge of AANE and signal-in-space, can help out in this area in a number of different ways. The company evaluates line-of-sight coverage for airfield surveillance radars, as well as the effects of terrain or building profiles on radio signal-in-space performance, by using modelling tools, such as ATDI HertzMapper, PHX Tools, AXIS and Ohio University navaids performance prediction models.

The company's standard safeguarding methodology for radar sites uses graphics that make the whole experience a more user-friendly one, which greatly benefits airport operators and air navigation service providers (ANSP). The technical staff and experts that work on safeguarding jobs evaluate construction carefully to find the ideal solutions available.
