This is all the clue.
(Other definitions for leeway that I've seen before include "Elbow room?" , "Room to manoeuvre, as for a ship" , "Amount of freedom" , "Limited room for manoeuvre" , "Flexibility" .)
(Other definitions for latitude that I've seen before include "Scope (with parallel circles?)" , "Scope for freedom of action" , "Unrestricted" , "Imaginery line around the earth" , "non-existent at the Equator?" .)
