    there are to ways to manage it
    
    1? the middel lattitude way already explained
    
    dif Lat : dL = M cos R
    departure : E = M sin R
    dif long : dG = E sec middel lat
    
    2? the meridional part way
    
    dif lat : dl = M cos R
    dif long: dG = Lc tan R
    
    
    M is the sailed distance
    R is the course
    Lc is de meridional part of Lat1 - meridional part of Lat 2
