Icing on UAVs is a global phenomenon, and icing conditions at the operational altitude can occur year round around the world. However, icing risks are particularly big in the sub arctics, Arctic and Antarctic. In large parts of the Nordics, for example, icing conditions are present from 35% to more than 80% of the time from September through ...
The use of deicing boots may enable an aircraft to be certified for flight into known icing conditions. However, they may not be sufficient to handle extremely severe icing, where ice can accumulate faster than the boots can shed it, or it accumulates on non-booted surfaces to the point where there is a dangerous loss of lift or control, or ...
One or two electrically-driven pumps send the fluid to proportioning units that divide the flow between areas to be protected. A second pump is used for redundancy, especially for aircraft certified for flight into known icing conditions, with additional mechanical pumps for the windshield. Fluid is forced through holes in panels on the leading ...

The program started in 1939 with two laws passed by Congress in April and June, [2] with the government paying for a 72-hour ground school course followed by 35 to 50 hours of flight instruction at facilities located near eleven colleges and universities. It was an unqualified success and provided a grand vision for its supporters – to ...
(The Center Square) – A proposed law would force Tennessee students to go without their cellular communication devices during instructional time. House Bill 932 is on the House calendar for Monday.
Icing conditions can be particularly dangerous to aircraft, as the built-up ice changes the aerodynamics of the flight surfaces and airframe and results in structural icing, which can increase the risk of a stall and potentially accidents. There are three types of structural icing: rime icing, clear (or glaze) icing, and mixed icing.
