The current value for the parameter is displayed on the overlay. Maximum and minimum values for the parameter are also displayed where appropriate.
The display line at the top of the overlay shows the value being entered. When you are satisfied with the entry, select OK and the new value will be entered into the simulation. The overlay is removed from the display.
If you are not satisfied with the entry, select AC to clear the complete entry or select CLR to clear the last input.
If you select Cancel, the overlay is removed from the display and the parameter reverts to its previous state.
When entering data, you will need to enter the figures exactly as required, except when entering heading values when the leading zeros are not required (030 can be entered as 30).
Latitude and longitude values can be entered as N, S, E or W in degrees, minutes, seconds and tenths of second (eg., N42_27’02.0”) (it is not necessary to type the degrees, minutes and seconds symbols).
Latitude and longitude will be displayed on the IOS in degrees, minutes and tenths of minutes, regardless of the format used to enter the values on the overlay. For example, a value entered as N42_27’30” will be displayed as N42_27.5.
If the selected parameter has pre–defined maximum and minimum limits, buttons to select maximum and minimum are displayed.
If the entered value exceeds the maximum or minimum limits for the selected parameter, the OK function is disabled and the entered value is displayed in red.
