Ok, that can only be in extremis when needs must and is therefore irrelevant to this discussion which is about the number of seats potentially available for the deployment and recovery of passengers during training and routine SAR Ops. It would be grossly irresponsible to make insecure passengers a day to day SOP.
The bottom line is the MRT standard load is six, the rearcrew need two seats, the role equipment would be inaccessible if all six remaining passenger seats were in position so two need to be removed. Therefore the MRT standard load requirement of the contract can't be met. Someone needs to have a rethink. Fast.
