      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

                                      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.
