The Japan Airspace SefetyMonitoring Agency (JASMA) is a combined organization
for airspace safety monitoring in Fukuoka Flight Information Region (FIR),
it consists of two parts, the Regional Monitoring Agency (RMA) and the
En-route Monitoring Agency (EMA). The RMA monitors the implementation and
continuing operation of Reduced Vertical Separation Minimum (RVSM) in designated
airspace using a vertical Collision Risk Model (CRM). The EMA also monitors
the implementation and continuing operation of Reduced Horizontal Separation
Minimum (RHSM) in designated airspace in both the lateral and longitudinale
dimension, using a horizontal CRM.
The RMA had been operating for several years in coordination with the Regional
Airspace Safety Monitoring Advisory Group (RASMAG) and was approved formally
in September 2007 of the Asia/Pacific Air Navigation Planning and Implementation
Regional Group (APANPIRG), International Civil Aviation Organization (ICAO)
Asia/Pacific Region. In September 2011, the function of the organization
has been expanded to include EMA function and has also changed its name
to the JASMA with APINPIRG approval.
The organization, now called as JASMA, has been operated by the Civil
Aviation Bureau (CAB), Ministry of Land, Infrastructure Transport and Tourism-(MLIT)-
Japan. The Air Traffic Control Association Japan (ATCA-J) has been supporting
some complementary parts of its operation in close coordination with JCAB
on contract basis.
