* Basic case of GDP is set up based on the economic growth rate which is a target of the Japanese future strategy.
(economic growth rate is set up to 1.7% from 2010 to 2017 and 2.0% from 2017 to 2032)
* In upper case, economic growth rate is set up 1% higher than basic case.
* In lower case, economic growth rate is set up 1% lower than basic case.

MET WG
Information Management WG
Cost-effectiveness analysis /
performance assessment Subgroup
Planning and Coordination Meeting
Advance PBN SG
General Aviation PBN SG
Research and Development promoting Subgroup
TBO ad-hoc
Data COM ad-hoc
Surveillances ad-hoc +
GNSS ad-hoc
*ATM: Air Traffic Management, PBN: Performance Based Navigation, RNAV: aRea NAVigation
The committee manages whole CARATS activity.
Each concrete discussion of the measure is carried out in each WG.
All of these meetings are collaborative activity in which JCAB, research institute,
manufacturer and airline have participated.
GNSS ad-hoc was established last year. 6
