A timeline across yesterday, today and tomorrow, with today shaded. An example NOTAM validity window is stamped onto today, then the planned RPA job slides onto the timeline. Three tiles below test the NOTAM in turn: time (do the windows overlap), place (is the job site inside the NOTAM area on a small map) and height (is the drone's operating height inside the NOTAM's vertical limits). Each tile shows an orange warning when it overlaps, or a grey dash when it does not. A final tag reads 'Affects the job' only when time, place and height all overlap, otherwise 'Does not apply'. Controls move the job time, the job place and the job height.
