Static cone, for an accurate static pressure measurement
Trailing cones (or trailing wires as they are often incorrectly called or trailing static cones), were first developed and tested in the 1950s and 1960s as a simple means of calibrating the static pressure (altitude reporting) error of an aircraft's pitot-static system. It does this by giving an accurate measurement of the ambient atmospheric pressure (static pressure) well clear of the aircraft's fuselage. The trailing cone system trails at least one fuselage length behind the aircraft (SpaceAg...
After a month pause, I’ve seen the new 777X -9 test flights become pretty active this week. And now there’s two of them using both BFI and PAE.
I wish I had been on this test flight today…
