Present novel and non-trivial system, device, and method for generating a temporary, pop-up, location-dependent clock to the pilot of an aircraft. A clock generator may be configured to retrieve approach procedure data representative of waypoint location such as the location of a final approach fix; receive navigation data representative aircraft location information; determine the passing of the waypoint inbound to the applicable airport; and perform one repetitive clock operation of a plurality of repetitive clock operations upon the passing of the waypoint, wherein an image data set is generated and provided to one or more display units. The image data set could be representative of (1) a pop-up timer displaying a counting down of time from the manually-initialized, estimated time, or (2) a pop-up stopwatch displaying a counting up of time when the estimated time is not manually initialized. |

1. A system for presenting a temporary, location-dependent clock to the pilot of an aircraft, said system comprising:
a manual input device; a source of procedure data; a source of navigation data; a clock generator configured to
retrieve procedure data representative of at least location information for one waypoint of a procedure,receive navigation data representative of at least aircraft location information,determine the passing of the waypoint as a function of the procedure data and the navigation data,perform one repetitive clock operation of a plurality of repetitive clock operations in response to the passing of the waypoint, where
a first repetitive clock operation is configured to
count down time from a time initialized manually via the manual input device,generate a first image data set representative of an image of a timer displaying time as the time is being counted down, andprovide the first image data set to at least one display unit, ora second repetitive clock operation is configured to
count up time from a time of zero,generate a second image data set representative of an image of a stopwatch displaying time as the time is being counted up, andprovide the second image data set to at least one display unit, where the performance of either the first repetitive clock operation or the second repetitive clock operation is dependent upon whether a time is initialized manually via the manual input device prior to arriving at the waypoint, and the image of the timer or the image of the stopwatch becomes visible and pops up into view in response to the passing of the waypoint; and at least one display unit configured to
receive the first image data set or the second image data set, andpresent the image represented in the first image data set or the second image data set, whereby
the passing of the waypoint is identified whenthe image of a timer or the image of a stopwatch
becomes visible,pops up into view, andbegins to either count time down or up, respectively. |
