          Principle
          A wing generates lift, in part, due to the difference in air pressure gradients on the wing surfaces: both upper and lower. During normal flight, the upper wing surface experiences reduced static air pressure and the lower surface comparatively higher static pressure. In normal flight, these air pressure differences also accelerate the mass of air downwards balancing momentum. However kinetic energy is proportional to the square of the velocity so designers aim to minimize the accelerated air velocities to reduce wasted energy in both the downward mass acceleration and wingtip vortices. Flying close to a surface increases air pressure on the lower wing surface (the ram or cushion effect) and decreases air acceleration so the ground effect improves the aircraft lift to drag ratios in two ways. Momentum is still balanced because the air pressure beneath the wing is pressing on the underlying surface—the water or flat land.

              Phasing:
              Phasing is a method used in echo sounder to determine depth of the sea bottom. In this method the speed of the stylus is kept constant and the range scale is changed from 0-100 mtrs , 100-200 mtrs , 200-300 mtrs and so on. It is important that the echo sounder range changed and regularly checked.

              Ranging:
              Ranging is technique were the scale of the echo sounder is kept constant and the stylus is varied according to the depth scale chose. E.g.- 0-100, 0-200, 0-300 mtrs ans so on

                              Particularly Sensitive Sea Area
                              (PSSA) is an area that needs
                              special protection through action
                              by IMO because of its
                              significance for recognized
                              ecological or socio-economic or
                              scientific reasons and which may
                              be vulnerable to damage by
                              international maritime activities.

                              not mutually exclusive. In many
                              cases a Particularly Sensitive Sea
                              Area may be identified within a

                                                    An ECDIS is a unified navigational information display which presents on an updated chart background,updated route,present position and fast track, combining these as approprite with radar,ARPA and other navigational sensors in order to improve safe navigational through the clear display of the situation in the vicinity of the ship.
                                                    chart can be corrected through a floppy disc,compact disc, even directly through the satellite systems. The latest system of updating charts is that the manufacturer transmit the chart updated as broadcast in coded format. Dedicated software is fitted in the ECDIS which will receive these updates,decode them and correct the charts.
