Triangle 3 After traveling a few more meters the pilot decides to define vertex 2 through the FAI triangle management menu As can be seen in Figure Figure 7 3 at the current position the base leg has 3 983 Km and the minimum and maximum possible triangle distances are respectively 9 053 Km and 14 12 Km Figure 7 4 Triangle 4 In the example of figure Figure 7 4 the pilot has just defined vertex 2 which is indicated by a circle in the Task map As the minimum distance for the second leg was not completed both areas are still present on the map Navigation is made through vertex 2 and the Triangle Size data field shows the minimum possible triangle size value which is now possible Note Both the Vertex 1 and Vertex 2 can be redefined in any moment Once the minimum distance for the second leg is passed the FAI triangle assistant module can decide based on the pilot position which area the pilot is navigating to At this moment navigation is set to the nearest point from vertex 1 and vertex 2 which satisfy the 28 rule This is shown on Figure Figure 7 5 where a line is draw between vertex 2 and such point 59 q a E i 1 600km A Figure 7 5 Triangle 5 The detection of vertex 3 is automatic and does not require pilot intervention Once the pilot enters the valid area the FAI triangle assistant module automatically uses the current position to define vertex 3 which is represent by a circle in the task map N
