It becomes easier to prevent many aerial accidents when the latest technology UAV can be combined with Manned Aircraft. Often, particular tasks are more suited to UAV than to a manned aircraft, due to the nature of the area surveyed. For example, in clear weather, a pilot or crew can make contact with a UAV and take avoiding action. The problem is much more significant for the UAV pilot to avoid a collision as the operator's field of view is severely limited. The situation is compounded as the UAV can neither receive nor transmit messages, orders, etc. except the remote pilot. He could be out of range of the manned aircraft in the area.The integration of UAV with manned aircraft is one of the critical aspects of BAF can ensure better usage of the available options for her. For aerial mapping, manned aircraft cannot cover a large and squalor area. In such a case, UAVs can be effectively used as an easy solution. Bangladesh has difficult borderline areas towards the southern side of the country, commonly known as the Chottogram hill tracts and few forest areas.
