3.2 Recent Short, Mid and Long
Term Researches
Long term target: realization of smooth,efficient and on time operation = Present target

Emphasized short and mid term targets:•Congestion relief and capacity increase interminal area and airport•Harmonization of domestic, international andover flights•On time operation under increased traffic•Expansion of GNSS operation•Performance evaluation of present
technologies for future operation22

 ENRI Short, Mid and Long term

research objectives
 Short term:• Precise analysis and estimation of present en-route, terminal and surface traffic characteristics• Evaluations of practical navigation systems

 Mid term:• Propose methods to respond short term
