Public Tolerance of Risk
Involuntary exposure
Unfamiliar
• Radioactive waste
• Commercial aviation
• Skateboards
• Lead paint
• Pesticides

Voluntary exposure
• Genetically modified organisms
Paul Slovic, 2000
Teleoperation• Reduced perceptual cues• Potential for reduced situational awareness• Control/consequence incompatibility• Latencies• Link management
Air Traffic
• Lack of out-the-window view• Timeliness of response?• Autonomous collision avoidance?• Lost link?• Impact on ATC workload and efficiency• Voice latencies
IFF transponder “IDENT”1. Remove right hand from control stick2. Move curser to tracker display3. Click on TOOLS menu4. Scroll to IFF5. Click to open IFF window6. Click “IDENT” button7. Click “APPLY”
Curser is accessed by trackball and Left/Right buttons
Note: In manned aircraft, the pilot response toATC-directed “IDENT” command is one step: 1. Push a button.
Fuel Heat Inhibit
Disable / Enable F9
Turning on the fuel heat system.
Note: This switch labeling has been changed to: “Fuel Heat: ON / OFF”
On-screen menu items refer to Function Keys for control.
Maintenance and Fault Diagnosis of IT Systems
• Ill-defined faults• Consumer hardware and software• Laptop use discipline
Maintenance and Fault Diagnosis of IT Systems
“The desktop computer, which was serving as the ground control system, locked up while the unmanned aircraft was in flight. The only alternative was to re-boot the computer, and this took about two to three minutes before command-and-control was reestablished. The unmanned aircraft’s flight path, however, was already uploaded so there was no effect on the flight.”
