Agree. This is EP surely? (Once tidal stream and direction have been added)

[@pzsc]

DR is when you only take into account direction and distance. EP is when you then allow for tidal flow.

Dear Sir, Correct me if I am wrong, but DR (Dead Reckoning) is a method to search for our position only by course and speed. Nothing more than this. This is why it is called "Dead Reckoning':
'Dead reckoning is the process of determining one’s present position by projecting course(s) and speed(s) from a known past position, and predicting a future position by projecting course(s) and speed(s) from a known present position. The DR position is only an approximate position because it does not allow for the effect of leeway, current, helmsman error, or compass error.'
best regards,
Captain Andy
