Safeguarding

  • Development in the vicinity of airports must be controlled to ensure that the safety and effectiveness of air operations are not impaired. Therefore, it is essential that any proposed building developments are assessed to ensure that there is no adverse effect on the airport operation or aircraft safety. The safeguarding activities recommended for all airports are: Physical, Instrument Flight Procedure (IFP) and Technical safeguarding.

ICAO ANNEX 14 and EASA ADR SAFEGUARDING


 

Physical Safeguarding is a process which considers how natural and man-made objects interact with the flight profile of an aircraft both in the air and on the ground. Cyrrus utilises 3D computer modelling of the obstacle environment to assess the effect of proposed developments on Obstacle Limitation Surfaces (OLS). Cyrrus also develops bespoke safeguarding criteria and maps for airports and facility operators. Advanced graphics are used to create easily interpreted user-friendly presentations.

TECHNICAL SAFEGUARDING


 

Cyrrus uses highly advanced software to enable computer simulations of Instrument Landing System, Very High Frequency Omni-directional Range, Distance Measuring Equipment and radar propagation modelling for Surveillance (primary and secondary radar) systems performance. The result of the modelling enables the impact of proposed developments on air operations to be assessed objectively and, where appropriate, to offer mitigation for development inside and outside of the airport without compromising aviation safety and efficiency.

IFP SAFEGUARDING


 

Associated with, but separate to the OLS, Cyrrus is able to evaluate the PANS-OPS surfaces used to develop conventional and satellite-based IFPs to assure safety in the air operation. The Cyrrus Surface Shield tool enables a quick and easy method of assessing the effects of proposed development located outside the airport but within the footprint of the flight procedures.

OTHER ASSESSMENTS


 

Where the reflections from construction material used on buildings (particularly roofs) or other structures (e.g. solar panels) might cause difficulties for the pilots of aircraft in flight, Cyrrus can complete a ‘Glint and Glare’ assessment. Also, large buildings established close to the runway and final approach can, under certain conditions, induce wind shear. Cyrrus has developed a modelling tool which provides a quantitative assessment of the potential wind turbulence affecting landing aircraft that might be caused by the erection of an individual construction. The model is based upon the reasoned methodology developed by NLR – the Netherlands Aerospace Centre.
