We highlight several potential observing programs for the Thirty Meter Telescope that impose technically challenging requirements on the performance and operation of the adaptive optics system(s). Some requirements impact the science instruments and the on-detector-guide-windows. Requirements that appear technically challenging include the time to setup the LGS/MCAO system, rapid real-time selection of guide stars for any position on the sky, use of extended AO guide objects, relative motions between several non-sidereal guide targets and AO operation in the vicinity of bright sources. Less challenging but still essential requirements include observation planning tools that allow identification of times when non-sidereal targets will pass next to suitable natural guide stars. AO performance estimates for extended guide targets and the availability of suitable AO guide stars over the whole sky are also shown.
