FEATURES◆ E-COurse Pilot measures XTD (Cross Track Distance) generated by
the sea current or wind, produces a virtual course line, and controls
the vessel to follow on that line.
◆ E-COurse Pilot reduces a "stray" off from the track, and helps thevessel to arrive the destination with shorter track distance.
◆ Compared to TCS, rudder to steer is kept small and infrequent. Thiscontributes to fuel saving effect. By combination with BNAAC control,
further powerful synergistic effect can be expected.
◆ Virtual course line is set automatically by "POWER ON". No need ofcomplicated operations!
◆ E-COurse Pilot is "ADD-ON" feature to the existing PT500 model.

特徴■ 潮流・風浪による横流れを計測し、船をコースライン上に制御
コースライン上の遠方に目的地を仮想設定し、操船制御■ 航路損失の増大を抑えることができ、短距離で目的地へ到達可能■ 舵角/頻度はTCSより少なくなり、省エネ性に寄与
舵制御をBNAACで行えば、さらに舵角/頻度は減少■ 電源ONで、コースラインを自動設定するため、複雑な操作が不要■ アドオンタイプのため、既存のオートパイロットへ増設が可能

Heading Control System
ヘディングコントロールシステム(オートパイロット)

Controlling of the vessel's heading through the water※ HCS controls the vessel's heading through the water. So, drift by current or wind is not controllable.
※ To compensate the “stray” and to keep the vessel on track, repeated manual adjustment of the heading
shall become necessary. This results in a longer rhumb line.
※ This also means an increased workload to the ship's crew, because the crew needs keep checking thevessel's position, and adjusting the heading, as may be required.
※ Drift by the current/wind is not controlled.
※ Loss of track is increased by several times heading changing.
※ The workload of crew is increased by several times position checking and heading changing.
◆※ 潮流・風浪による横流れまでは制御しない※ コースラインからのずれと修正を繰り返し行うため、航路損失が発生し、航程が増える※ 設定船首方位の変更が都度行われ、航海士の負荷が増える

E-COurse Pilot

Controlling of the vessel on the planned course line
※ E-COurse Pilot minimizes a stray off from the track, by generating a virtual course, and keeping the vessel
to follow on that line.
※ Unlike HCS, repeated manual adjustment of heading is not required.
※ Compared to TCS, which requires a precise control, E-COurse Pilot realizes fuel-saving, by simply keeping
the vessel on the course by small/infrequent rudder to steer. Operations are as simple as just power on!
※ The vessel can expect further powerful synergistic effect by using E-COurse Pilot and BNAAC, together.
※ 遠方に目的地を仮想設定し、航路損失を最小限に※ コースラインからのずれに対する、頻繁な方位変更が不要※ TCSのような緻密な制御はせず、最小の舵角・頻度で、コースラインへ復旧※ ECDIS上での航路計画は不要で、電源ONのみで対地制御を開始※ BNAACとの組合せでさらなる省エネ性を発揮
