A method for prompting an operator to reply to a first data link message before it expires includes receiving the first data link message, storing the first data link message, starting a timer at an initial timer value when the first data link message is received, determining whether a response to the first data link message has been input, determining whether the timer will expire in less than a predefined amount of time, requesting an input from the operator before the timer expires, determining whether the input has been received since requesting input, and determining whether the timer has expired before the input is received. In cases where the input is received before the timer expires, a second data link message is sent. In cases where the input is not received before the timer expires, a status for the first data link message is set to expired.
