The vessel should be flying her ensign and also her signal letters and the requisite pilot signal when approaching the pilot station. The international signals, as well as any local port signals, can be found in the Sailing Directions, which is also known as the "Pilot Book" When a pilot is required most ports now require due notice of the vessel's ETA to be sent in by radio. However, this does not relieve the ship's obligation to display the pilot signal ("G" by any of the methods of signaling ) until the pilot is aboard when "H" flag will be flown. If the master or first mate of the vessel has a pilotage certificate for the district then the above is unnecessary, in such case the pilot flag (white and red horizontal halves, as on the pilot vessel) will be flown. 在到达英国之前,船长会在引航站通知他的业主或代理到达目的港的大致时间。船舶应该在靠近引航站时升起船旗和她的信号字以及必要的控制信号。国际信号,以及本地港口的任何信号,都可以在航路指南也叫做水路指南的书中找到。大多数港口现在需要引航员通过无线电适时通知其船只的预计到达时间。但是,只有当引航员在甲板上升起H旗才算是免除船舶显示控制信号的义务(“G“的通过对信号的方法之一)。如果该船只的船长或大副有一个该区的引航证,则不需要进行上述行为。在这种情况下,将需升起引航旗。 B 005.
