Folie 9

Desired operation

• Targeted observations based on sensitive area predictions and meteorological weather phenomena

• Launch of dropsondes

• Flight routes off-airways

• Flight level 270 - 370

• Night time / weekend operation

• Access to aircraft for crew / scientists also during night time / weekends

• overnight stop at Okinawa (Kadena AB (RODN) or Naha airport (ROAH))

• Refueling stop at Iwo Jima (RJAW) ??

• Refueling stops at civil / (military?) airports in Taiwan, Japan, South Korea, Russia (only during transfer flight)

Limitations

Aircraft:

• Max. crosswind component during take-off and landing: 20 (25) kts• max. flight altitude: FL 420 – can only be reached at end of the flight for 45 – 60 minutes – initial climb to FL 350/360, stay there for about 1.5 hrs, then continue climb to FL 380, stay there for a while, then final climb• has to be parked inside hangar before taifun may hit – especially important for deployment in Kadena (also not close alternate airport!)• max. range: strongly depends on wind and availability of suitable alternate airport, 1200 – 1500 NM

Crew duty times (defined by law):

• day-off after 6 days at the latest• normal duty time: 10 hrs, then 10 hrs rest time; can be extended to max. 14 hrs (max. 8 hrs in total in 7 days); rest time grows accordingly
