Hazard definition and identification
- A hazard is a corrupted or incomplete perception of
visual information in the context of ATCOs tasks
- 27 hazards were identified by 5 ATCOs in a workshop
- 13 with severity class A (Accident)
- Proposed hazard classification

Hazard examples
Inability to
- detect objects on RWY when checking RWY occupancy for
giving a landing clearance (wildlife, a/ c, ground vehicles, pedestrian)
- detect weather conditions (wind shearing)
- check a/ c for abnormal appearance (protection of Pitot-
sensors not removed, engine failure and smoke generation)
- check gears in the case of a low pass tower
- detect unauthorized movements in the area of responsibility
- to immediately detect go arounds of a/ c
A complete overview will be published soon.

Motivation and approach Which design parameters contribute most to mitigate risk? Assum ptions
- A set of configuration setups of the HMI are available
- Boundary conditions are determined
– Weather – Traffic volume / density – Airport layout – Concept of operations
Concept
- Provoke hazard occurrence by performing experiments
(HIL) with threat appearance
- Varying design parameters (assumed as independent
input variable)
- Assess HMI setups by resulting frequency of occurrence

Experimental concept
- Operational scenario includes
– Inbound traffic (automated landing clearances) – Outbound traffic (automated push back and taxi clearance) – Hazard appearances – Airport (single runway layout)
- Primary Task
– Clear for lineup – Clear for take off
- Secondary Task
– Detect threat events

Violation of the primary task
- The missing ground
surveillance (B) contributes most to the frequency of RWY incursion and violation of vortex separation minima.
- The panoramic view/
ground surveillance availability (A) contributes least.

Conclusion
- An assessment of HMI setups has been
performed that points out contributing effects on the probability of hazard
- ccurrence.
- The assessment identifies safety relevant
design parameters.
- The development of safety requirements may
take into account identified safety relevant design parameters.
