ATS 3.17 CONFLICT DETECTION TOOLS

Conflict Detection Tools (CDTs) are computer based Controller Tools that identify conflicts and then provide system generated conflict advice to controllers. CDTs can either provide conflict detection continually or provide one-off probes (modelling to assess the potential conflicts on an … Continued

ATS 3.16 THE USE OF SAFETY NETS IN ATM

The use of safety nets within the ATM system has been established for many years. The scope of safety nets has extended to be not only airborne based but ground based as well. There is a move to extend their … Continued

ATS 3.15 (ADVANCED) STRATEGIC LATERAL OFFSET PROCEDURES

Strategic Lateral Offset Procedures (SLOP) are mitigating the risk of vertical collision and wake turbulence encounters between aircraft with high precision navigation capabilities. Provisions of SLOP are published in ICAO Doc 4444 (PANS-ATM) as special procedures for oceanic and remote … Continued

ATS 3.14 SYSTEM DEFENCES DURING PLANNED SYSTEM DEGRADATION

Planned System Degradation could be any potential reduction in the availability, reliability or integrity of any part of the ATM system, known in advance to the user of the system. IFATCA Policy is: Risk assessment and appropriate mitigation should be … Continued

ATS 3.13 VIRTUAL CENTERS AND FUNCTIONAL AIRSPACE BLOCKS

The worldwide patchwork of FIRs and associated ANSPs is a cause of operational and organisational inefficiencies. In Europe, where the problem is most pronounced due to the large number of states and flights, functional airspace blocks (FABs) were envisaged as … Continued

ATS 3.12 MIXED MODE OPERATIONS

The ATM system will continue to evolve through the use of technology. To permit certain categories of non-equipped flights to operate in mandatory equipage airspace, exemptions are given. The controller is often used as the mitigation to permit these flights … Continued

ATS 3.11 AVIATION RADIO FREQUENCY SPECTRUM PROTECTION

Spectrum Protection refers to the management of the radio-frequency spectrum in order to protect particular interests. The spectrum includes not only communications and datalink applications, but also navigation and other uses. Aviation is just one of the many users of … Continued

ATS 3.10 UNITS OF MEASUREMENT IN CIVIL AVIATION

IFATCA takes the view that SI (Système International d’Unités) is not necessarily providing a single solution for Civil Aviation, and that, in order to obtain a common global standard which is necessary for safety reasons, then specific non SI elements … Continued

ATS 3.9 GLOBAL COMPATIBLE FLIGHT LEVEL SYSTEMS

There currently exist three systems for flight level determination which are not compatible with one another. In the interface areas safety is compromised. IFATCA Policy is: A global solution shall be developed using one system of flight level determination. The … Continued

ATS 3.8 RADAR MONITORING

Radar monitoring is one of the functions in the provision of an air traffic control service. For the purposes of this policy, it has been considered in two areas, namely: arrival / departure phase and the en-route phase. The need … Continued
