Maximum Latitude Due to maximum latitude being exceeded, system inaccuracies may
Exceeded develop and functionality may be disabled. Inaccuracies generally
become more serious as own ship travels toward the pole after
exceeding the maximum latitude. Do not rely on system as primary
means of navigation when operating beyond the maximum
latitude.
Minimal Safety Region A low value for look-ahead time or distance has resulted in a small

This may not provide adequate time to take action if a danger is
detected. Use the 'Chart Dangers' menu to increase look-ahead if
necessary.
