140 with the olds RATS, 125 with the newer ones. How do you tell? If you have a look at the upper CB panel and if two CBs have yellow collars (D 02 - Anti Ice Pitot 1 and F 07 - ADIRU 1) then it's an old style RAT. These C/Bs are pulled to extend flight time on Batteries only to at least 30 minutes and are only part of the drill for the older aircraft.
