Wind Calculation is a full screen page with the following structure:
Fig. 10.5 - Wind Calculation page
The EKP-III computes wind velocity and direction from the information entered

data. ETE to Waypoint is also based on GPS Ground Speed and Track.
data. ETE to Waypoint is also based on GPS Ground Speed and Track.
Wind information will be recomputed when the heading, air speed, air temperature or
Altitude values are edited.
NOTE
The wind calculator does not correct for local barometric pressure, which may not be known accurately
enroute. The values produced by the wind calculator may therefore differ from the true winds by up to 5%.
10.6 FUEL CONSUMPTION
The EKP-III computes Fuel Consumption for each leg of the active Flight Plan or the fuel
used in flight, based on entries made by the pilot. This is a useful feature for flight planning
purposes. Actual Fuel Consumption will vary based on flight conditions and engine settings.
