Aviation Glossary :: SAFETY LOGIC SYSTEM ALERTS  Aviation Glossary :: SAFETY LOGIC SYSTEM ALERTS FAA Written Test Preparation
Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

  1. ALERT- An actual situation involving two real safety logic tracks (aircraft/aircraft, aircraft/vehicle, or aircraft/other tangible object) that safety logic has predicted will result in an imminent collision, based upon the current set of Safety Logic parameters.
  3. Alerts generated by one or more false surface-radar targets that the system has interpreted as real tracks and placed into safety logic.
  4. Alerts in which the safety logic software did not perform correctly, based upon the design specifications and the current set of Safety Logic parameters.
  5. The alert is generated by surface radar targets caused by moderate or greater precipitation.
  6. NUISANCE ALERT- An alert in which one or more of the following is true:
  7. The alert is generated by a known situation that is not considered an unsafe operation, such as LAHSO or other approved operations.
  8. The alert is generated by inaccurate secondary radar data received by the Safety Logic System.
  9. One or more of the aircraft involved in the alert is not intending to use a runway (for example, helicopter, pipeline patrol, non-Mode C overflight, etc.).
  10. VALID NON-ALERT- A situation in which the safety logic software correctly determines that an alert is not required, based upon the design specifications and the current set of Safety Logic parameters.
  11. I NVALID NON-ALERT- A situation in which the safety logic software did not issue an alert when an alert was required, based upon the design specifications.
