Air Traffic System Technologies

  1. 1. Air Traffic System Technologies Improving safety in ATC
  2. 2. FAA’s Mission <ul><li>To promote safe orderly and expeditious flow of traffic </li></ul><ul><li>FAA’s ATC Mission-to separate and facilitate efficient movement of air traffic </li></ul><ul><li>Accomplished by: ATC towers for departure and landing,to include taxiing, (TRACON) Terminal area facilities for approach separation and control and enroute facilities (ARTCC) </li></ul>
  3. 3. Issues of Air Traffic Control <ul><li>Traffic growth in certain areas </li></ul><ul><li>Capacity issues at airports </li></ul><ul><li>Runway incursions </li></ul><ul><li>Aging equipment </li></ul><ul><li>High stress workplace </li></ul>
  4. 4. NASP National Airspace System Plan <ul><li>1981-comprehensive modernization and expanded capacity plan </li></ul><ul><li>Slowed down by congressional funding </li></ul><ul><li>And technology problems </li></ul><ul><li>Included: New computer systems at ARTCC which includes backup systems for failure, replacement of controller consoles with sector suite, advanced automation system with new computer and software </li></ul>
  5. 5. How the system works <ul><li>Takeoff/departure- tower controls to five miles and then hands off to a TRACON </li></ul><ul><li>Enroute-air route surveillance radar picks up aircraft for the ARTCC </li></ul><ul><li>Approach and Landing-aircraft is picked up at least 30 miles out by a surveillance radar and approach control and then handed off to tower at 5 miles for landing and taxi </li></ul>
  6. 6. Takeoff and landing technologies <ul><li>Terminal doppler weather radar-provides wind shear and microburst alerts </li></ul><ul><li>Airport Surface Target ID (ATIDS)-for prevention of runway incursions/uses ASDE-3 Ground radar and ARTS terminal and GPS to feed into Airport Movement Area Safety System </li></ul><ul><li>Precision runway monitor- reduces landing separation at parallel runways using newer software </li></ul>
  7. 7. Arrival/departure equipment <ul><li>(ARTS) automated radar surface system will be replaced by (STARS) standard terminal automated replacement system </li></ul><ul><li>The goal is to improve ARTS until STARS can fully replace it </li></ul><ul><li>Upgrade ASR 4/5/6 to ASR 7/8/9-ASR 9 is fully digitalized radar with a 60 mile radius for tracking weather </li></ul>
  8. 8. Enroute technologies <ul><li>Preferred routing via on board weather radar,TCAS and GPS </li></ul><ul><li>Automation for improvements in air traffic management/Central Flow Control Center in D.C. can order traffic to be held if traffic exceeds capacity </li></ul><ul><li>(AERA) Advanced enroute automation helps aircraft fly preferred routes safely </li></ul><ul><li>(ATMS)Allows for more efficient management of traffic enroute </li></ul><ul><li>(ADS)Uses satellites for oceanic routes to improve spacing and is part of the operational oceanic display </li></ul>
  9. 9. Other technologies <ul><li>Data link communications- could tremendously improve communications between aircraft and ground controllers, especially where the language barrier is involved </li></ul><ul><li>GPS will allow direct path navigation instead of routing using ground Navigation equipment like VOR and TACAN enroute and will also be used for approaches where applicable for all weather landing </li></ul>
  10. 10. Where will GPS be used in the future? <ul><li>At one point in the mid 1990’s the FAA promoted GPS to replace all other equipment by the year 2001, and why couldn’t this occur after having the military successfully field test it for years and the benefits are: increased operational efficiency and safety, decreased costs, precise navigation,preferred routes, reduced separation, precision approach capable and lower avionics cost. </li></ul>
  11. 11. Where will GPS be continued? <ul><li>However the GPS precision approaches have yet to be proven completed reliable. </li></ul><ul><li>Security dictates that a small size GPS jammer can disable the use of a GPS and the jammers are difficult to locate </li></ul><ul><li>ILS and MLS are highly accurate and are currently more reliable especially for CAT III approaches </li></ul>
  12. 12. The future dictates a multimode receiver and tested in Free Flight <ul><li>Aircraft will be able to use MLS or GPS to fly the same ILS approach through the use of a multi-mode receiver, and WAAS and LAAWS </li></ul><ul><li>These are currently being made by AlliedSignal,Rockwell Collins, and Sextant Avioniques </li></ul><ul><li>Technologies such as these will be tested in the FAA’s New ATC improvement program called FREE FLIGHT </li></ul>
