10. T-Parc prep visit > A.Hausold > 05. Oct 2007 Folie 10 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
