Yes – because an ECDIS in track control will do the computation and steer the route.
When handing over the con of a vessel to a pilot, should the Master insist in discussing the passage plan with the pilot while he is there to use his local knowledge and advice on the navigation of the ship?
The passage is well established and known by the pilot, and a plan is therefore not necessary.
A passage plan should be discussed between the Master and pilot, when under pilotage in the same way as discussed with the bridge team when deep sea.
The pilot would probably consider it unnecessary, be more interested in knowing the ship’s characteristics and resist any passage planning discussions with the Master.
