An aircraft is described. The aircraft includes an avionics management system including one or more control display units. The control display units include an alphanumeric keyboard. By the alphanumeric keyboard, an operator within the aircraft may input a personal identification number (PIN). The input PIN is received from the alphanumeric keyboard and compared with a PIN stored in memory. When the input PIN is validated, the avionics management system changes a system state from not validated to validated, thereby permitting the control display unit to access otherwise unavailable mobile user objective system (MUOS) feature sets, such as viewing MUOS presets or tuning to the MUOS presets.
