Following extract is from GCAA CAAP14 - ULR, section 7 -
(c) ULR Flight Rest Period Away from Base
In the ULR Rostered Duty Assignment, the scheduled period free of flying duties away from base shall be at least 48 hours.
Seems pretty clear to me.....
Unfortunately, as was mentioned in one of the ASR's a few weeks ago, EK doesn't need to follow GCAA CAAP 14 rules n their ULR. The EK ULR's are published as a VARIATION in the EK OM-A, which is approved by the GCAA.
PS: The ASR was regarding cabin crew on A380 not having the required minimum rest on a ULR as per the GCAA CAAP.
