A method to generate a clearance request to deviate from a flight plan is provided. The method includes receiving at one or more processors in an airborne vehicle input from at least one automatic flight-plan-relevant source, at least one of the one or more processors independently determining a revised flight route based on the received input, at least one of the one or more processors independently generating a preconfigured clearance request message to deviate from the flight plan for a flight crew user based on the determining. The method further includes providing an audible prompt to the flight crew user for one of approval and rejection of the clearance request to deviate from the flight plan. When an approval of the clearance request to deviate from the flight plan is received from the flight crew user, the preconfigured clearance request message is downlinked.
