YEOMAN Sport 19
5. Chart library and referencing
Before using YEOMAN, a chart must be entered into the
CHART LIBRARY and referenced. This requires the entry of
the latitude and longitude of three positions on the grid
intersections as below. The positions should be as far apart as
practicable and marked clearly.
THE LATITUDE OF POSITION 2 MUST BE THE SAME AS
THAT OF POSITION 1. THE LONGITUDE OF POSITION 3
MUST BE THE SAME AS THAT OF POSITION 2.
IF THE CHART MOVES ON THE CHART TABLE AFTER
REFERENCING IT MUST BE RE-REFERENCED.
Position 1 and Position 2 must be further than 50mm apart.
It is possible to reference a chart with only two reference
positions and this is described in Section 11.5.
For units shipped in the USA with the BBA Chartkit library then
Positions 1, 2 and 3 are replaced by Positions A, B and C.
