Have just a general comment on TCA charts. We (part 121 operators) are restr from operating below the floor of the TCA when arriving at the primary airport. This requires one pilot to be head down trying to decipher the TCA chart. To compound the problem, approach controllers will clear aircraft to their MVA, in some instances below the bottom of the TCA. Example: las creso arrival, clearance to 7000 ft in the sector with a min of 8000 ft. The controller is legal but perhaps the rule could be changed, requiring clrncs to keep us in the TCA.
