[2] [Distance calculation mode] 
Set a method for calculating a distance between WPTs. 
When [Straight] is selected, a distance between WPTs is calculated with a straight line 
 
When [with Turn] is selected, a distance between WPTs is calculated based on the expected route. 
 
[3] [Monitoring] 
Set a route monitoring method. 
When [Wheel-over line] (steering line) is selected, monitoring is performed by using Wheel-over line 
(WOL) along each WPT. 
 
 
 
When [Arrival circle] is selected, monitoring is performed by using the arrival circle along each WPT.
