Description of simulation

You can drag the slider, the wheel, or the windmarker, and see exactly what the current wind-triangle is. On the right of the Flight Computer you see the current wind triangle as you would normally envisage it, North up.
The Flight Computer can be used with either the airvector or groundvector ending in the grommet. The buttons on the Flight Computer allow you to switch between these two modes, while keeping all vectors the same
The "Flip sides" button is available to switch between low and high speed range.


Definitions:
TT True Track, often called Course
GS Ground Speed
TH True Heading
TAS True Air Speed
W Wind direction
V Wind speed
WCA Wind Correction Angle (positive: correct to right)
CWC Cross Wind Component:
V*sin(W-TT), sign equal to WCA sign
TWC Track Wind Component:
-V*cos(TT-W), negative number is headwind, pos. is tailwind
EWC Effective Wind Component: GS - TAS
