Numeric Keypad
The Numeric Keypad (see right) or the Slew Tool (see 5.4.1)
is
displayed automatically when a touch point is selected which
requires a numeric data input. The overlay displayed is
determined by which format was last used. A button on each
overlay (Slew/Keypad) allows you to select the other format
for display.
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 (e.g., 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.
