NASA has developed a tool called Dynamic Weather Routes to automatically adjust flight paths for aircraft around hazardous weather. Currently American Airlines has it in use. The tool reduces flight times and fuel costs to the airlines.
This is interesting technology which with the Aerobatic Innovations post a couple days ago can bring this technology down to the UAV level for future flights if Aerobatic Innovations chooses to collaborate with NASA. It can allow UAV operators to also monitor the current weather conditions, even with low level flights of 400ft or lower to gauge when the UAV needs to come down until conditions improve (and then can also be ready for disaster survey immediately afterwards).
