This is a small update to the grammaphone that changes the convoy speed chart to a sort of “reference card” to help in manual targeting. Information includes torpedo data as well as AOB, Speed, and Range formula.
It also includes a table to aid in determining the “lead” angle required to set in the periscope when using what has been referred to as the “Dick O’Kane” method for launching torpedoes.
Credit to Hitman for his sinus scale which has been included to aid in the AOB formula, also included from his tutorial.
This is JSGME ready since there is no need to change anything in the “menu_1024_768.ini” file.
Readme included.
