Is an off duty pilot allowed to occupy the flight deck jumpseat?

An off-duty pilot is indeed allowed to occupy the flight deck jumpseat. This policy is established to enable pilots to remain informed about operational practices, procedures, and to gain valuable experience while observing active flight operations. Having off-duty pilots in the jumpseat can also enhance safety and provide a qualified individual who can assist the flight crew if necessary.

While options relating to being "current" or stipulating "only during training" may hold significance in other contexts, they don't accurately reflect the general allowance for off-duty pilots to occupy the jumpseat. This access is intended to foster a culture of learning and support among pilots, regardless of their current status.
