In the design of a military aircraft it is necessary to adhere to the requirements of MIL-STD-1472 “Human engineering design criteria for military systems, equipment and facilities”. Among other things it defines the placement of switches, the juxtaposition of switches and the distances between switches. This is not to say that they don’t get it wrong sometimes but when they do there is a change order written and the designs modified and implemented when possible. However on a civil aircraft even though they are used in the military the pilots get what the designers give them. If the military operator finds a problem they pay to have it rectified. If a civil operator finds a problem he gets an STC and then he can sell the change to other operators.
In the meantime what you see is what you get. WYSIWYG
