Figure 5.
Multivariate matrix of drone flyability as influenced by air temperature, wind speed, and precipitation in the 100 most populated world cities21. Each interior plot shows median flyability as a function of minimum and maximum temperature tolerances. The vertical position of interior plots corresponds to precipitation thresholds, the horizontal position of interior plots corresponds to maximum wind speed resistance. The stars correspond to the CD (black) and WRD (yellow) to benchmark potential flyability gains. The arrow shows the greatest opportunity for improving flyability for CDs—increasing precipitation threshold by 1 mm/h and maximum wind speed resistance by 5 m/s.
