A manager of a foreign airline: The newly developed collision avoidance system, although not yet fully tested to detect potential problems, must be installed immediately on the passenger plane because the system's mechanical alarms can prevent the pilot from colliding with the plane
The airline pilot: The pilot can not fly an aircraft with an collision avoidance system that has not been fully tested, because a faulty collision avoidance system will mislead the pilot and cause a crash
While collision avoidance systems can help pilots avoid some crashes, potential problems with untested collision avoidance systems could lead to more crashes.
