Purpose: to offer enhancements for ground-based safety nets.
To research particularities of ground-based safety nets operation
To compare different approaches to visual representation of traffic collision alerts in different automated ATSs
To search for the drawbacks of existing approach to visual representation of short term collision alert
To provide countermeasures that can eliminate aforementioned drawbacks

Topicality
Nowadays, considerable progress has been made in matters of flight safety. However, taking into
consideration vast increase of air traffic volumes, additional improvements are needed and can be
achieved. It is well known that majority of aviation accidents happen due to system errors associated with human factor. Therefore, any improvement
connected with this field would potentially increase overall safety of the whole aviation system.

Implementation benefits of STCA
resolution advisory
Decreased reaction time toward conflict resolution
Reduced number of separation infringements
Elimination of human factor related errors
Improvement of air traffic flows

Conclusions
Taking into consideration that one of the main goals of all
processes in aviation system is to reach proper level of
flight's safety, while keeping positive income rate, cheap
solutions to improve existing services are very attractive.
New functional can be added to the existing short term
collision avoidance system without changing core
principles of its operation. Considering the rate of traffic
volumes increase, this upgrade is expected to have a
positive effect on safety of flights.

Recommendations
To perform research of STCA warnings and
their resolution for different portions of
existing airspace
Where necessary, upgrade automated air
traffic systems with resolution advisory for
short term collision alert component
