Helo/C130 KB holding: KB requires how many keypads and what dimension?

Explanation:
In a Helo/C130 keyboard-holding scenario, the input hardware must balance enough input options with tight cockpit space and quick usability. A single compact keypad sized 5 by 5 provides 25 distinct keys, which is typically enough for essential numeric input and a few function controls, while keeping the control surface uncluttered and easy to reach in high-stress moments. A much larger 15 by 15 area would be bulky and impractical for an aircraft cockpit, adding unnecessary weight and complexity. Adding more than one keypad would also complicate the layout and increase the effort needed to locate and press the right key during operations. So the most sensible and practical choice is one keypad with a 5x5 dimension.
