Distance Flown = 26.875 Km
f. Calculate Leg Crosstrack Error:
Formula:
XTK
SIN OTE X Flown Distance X 100
Actual Distance
NOTE
This calculation determines leg crosstrack
error expressed in percent of distance trav-
eled.
Example Calculation:
XTK
(SIN 0.633) (26.885Km) 100
26.738 Km
XTK Error = 1.11% Distance Travelled
g. Calculate Leg Alongtrack Error:
Formula:
ATK
COS TE (Flown Dist Actual Dist 100)
Actual Distance
NOTE
This calculation determines leg alongtrack
error expressed in percent of distance trav-
eled.
Example Calculation:
ATK
(COS 0.633) (26.885 26.738Km) 100
26.738Km
