Peck talks about the ban on the US Air Force's RQ-4 Global Hawks flying in icing weather. The high-flying unmanned intelligence planes were pressed into service during the wars in Iraq and Afghanistan without de-icing systems, and test flights conducted in April and May now suggest that the planes might not need them. Responding to ice is a particularly sensitive issue for unmanned aircraft like the Global Hawks. Unlike other drones, Global Hawks have ice sensors that can alert their pilots to icing conditions.
No de-icing necessary?
