Self-control in the skies; an onboard device for flying closer together more safely

Article Abstract:

An altitude-reporting radar system, designed to help avoid midair aircraft collisions, has greatly improved airline safety in the US. However, the system is being replaced by another that has additional advantages, such as the ability to help reduce runway accidents.

Throttled: manufacturers balk at steering and landing with engine thrust alone

Article Abstract:

Dryden Flight Research Center in Edwards, CA, is testing Propulsion Controlled Aircraft (PCA), a computerized system to control an airplane's direction and altitude merely by manipulating engine thrust. Airplane manufacturers believe such a system is unnecessary, as conventional and backup control systems rarely fail simultaneously.

Collision Decision: new radar systems may prevent deadly accidents on congested runways

Article Abstract:

Runway incursion incidents have steadily increased in recent years, numbering 321 in 1999 and 403 in 2000. Both the FAA and NASA have developed ground-based radar detection and warning systems. The FAA's Airport Surface Detection Equipment (ASDE) determines vehicle path and relays the information to air traffic control monitors. The Runway Incursion Prevention System (RIPS) developed by NASA is part of a comprehensive system designed to give a pilot reliable information of an aircraft's surroundings under any conditions.
