AoI

The Angle of Incidence diff is shown in the wing view as triangle in millimeters if no ref is selected. Plus means faster. Minus means slower.

ref

The current main/row or suspension point that is set as reference to calculate relative deviations. The referenced object is marked with a border.
You can select/change the ref by:

groups and rows	Using the radio buttons () or click on the grey rows or names of the main lines in the wing at the top.
points	Clicking the white area beneath the suspension point name

nom

The nominal length between suspension point and main riser loop.

rdg

The actual reading from your measurement device. When measuring, rdg is the input field.

diff

The difference between nom and rdg. This value depends on the currently selected ref. If nothing is selected, the actual deviations from rdg to nom are displayed.

colors

Areas marked in red color are further away (the line is longer) than the selected ref. Areas marked in blue color are closer (the line is shorter) than the selected ref.

status

Color coded dots are shown for manual, imported & laser values

Averages of group AR1

Formula of calculation:

sum(A1,A2,A3,A4) / 4

Statistics of group AR1

Evidence must be high for the system to show colored dots at all.

Evidence levels

Low: 3 datasets found and quality is below 18
Medium: 3 datasets found and quality higher than 17
High: 10 datasets found and quality is at least 25 / 3 datasets found and quality is at least 50

The color of the dot itself is based on the spread.

Color codes

Green (reliable): Spread is less than or equal to 2.0. Chances are high that you will get a very similar result.
Yellow (uncertain): Spread is less than or equal to 3.0. Your result might diverge from the expected length change.
Orange (unreliable): Spread is greater than 3.0. Given the data we have, the length change might be something but what expected.

Formula of calculation:

sum(A9,A10,A11,A12,A13,A14) / 6

Statistics of group ARL3

Evidence must be high for the system to show colored dots at all.

Evidence levels

Low: 3 datasets found and quality is below 18
Medium: 3 datasets found and quality higher than 17
High: 10 datasets found and quality is at least 25 / 3 datasets found and quality is at least 50

The color of the dot itself is based on the spread.

Color codes

Green (reliable): Spread is less than or equal to 2.0. Chances are high that you will get a very similar result.
Yellow (uncertain): Spread is less than or equal to 3.0. Your result might diverge from the expected length change.
Orange (unreliable): Spread is greater than 3.0. Given the data we have, the length change might be something but what expected.
