GM1 ORO.FTL.105(1) Definitions ED Decision 2019/019/R ACCLIMATISED (a) A crew member remains acclimatised to the local time of his or her reference time during 47 hours 59 minutes after reporting no matter how many time zones he/she has crossed. (b) The maximum daily FDP for acclimatised crew members is determined by using table 1 of [ORO.FTL.205(b)(1)](#_DxCrossRefBm318085106) with the reference time of the point of departure. As soon as 48 hours have elapsed, the state of acclimatisation is derived from the time elapsed since reporting at reference time and the number of time zones crossed. (c) A crew member is considered to be in an unknown state of acclimatisation after the first 48 hours of the rotation have elapsed unless he or she remains in the first arrival destination time zone (either for rest or any duties) in accordance with the table in [ORO.FTL.105(1)](#_DxCrossRefBm318085309). (d) Should a crew member’s rotation include additional duties that end in a different time zone than his or her first arrival destination’s time zone while he or she is considered to be in an unknown state of acclimatisation, then the crew member remains in an unknown state of acclimatisation until he or she: (1) has taken the rest period required by [CS FTL.1.235(b)(3)](#_DxCrossRefBm318085866) at home base; (2) has taken the rest period required by [CS FTL.1.235(b)(3)](#_DxCrossRefBm318085866) at the new location; or (3) has been undertaking duties starting at and returning to the time zone of the new location until he or she becomes acclimatised in accordance with the values in the table in [ORO.FTL.105(1)](#_DxCrossRefBm318085309). To determine the state of acclimatisation, the two following criteria should be applied: (i) the greater of the time differences between the time zone where he or she was last acclimatised or the local time of his or her last departure point and the new location; and (ii) the time elapsed since reporting at home base for the first time during the rotation.
