We have been designing control wheels for over 50 years. They have flown on the U-2 and TR-1, the C-141, the Beech 400A the Saab 340 and all models of C-130. Design materials have included magnesium, aluminum and powder-coated wheels. They have been available with lighted chart holders.
Each design has been customized to the application. We have integrated many functions on the C130J control wheel that were previously located elsewhere in the cockpit (HOTAS). This allows the pilots to keep their hands on the control wheel and eyes where they need to be focused.
