    IATA delay codes were created to standardise the reporting by airlines of commercial flight departure delays. Previously, every airline had its own system, which made the sharing and aggregation of flight delay information difficult.

  5. Laser designator - Wikipedia

    en.wikipedia.org/wiki/Laser_designator

    When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded laser pulses, also called PRF codes (pulse repetition frequency), are fired at the target.

  6. Open reading frame - Wikipedia
