I can only comment on EASA FTL and state that reporting at certain times in the afternoon the limits are more restrictive than the old UK CAP371 which many a Pilot will tell you was "safe"
This is because you'll be landing in the WOCL - This suggests to me (and many a pilot will tell me i'm talking rubbish) that EASA applied some science when coming up with their numbers.
UAE GCAA or EASA FTL are not compliant with FAR FTL's - you might find that FAR are more flexible sorry...
