There will come the day that UAVs can fly into the airspace of manned aircraft in the near future because of the increasing number of operational UAVs, together with technologies development. Since pilots of UAVs are on the ground, the equipment for sensing and avoiding obstacles in front is indispensable. In this paper, the TCAS II, a collision avoidance device for manned aircraft, is implemented to UAVs and investigated for the interfaces of a flight control computer. It turns out that the onboard directional antenna of TCAS II does not provide precise direction information, and the TCAS II is not assumed to be installed alone, but used as supplement with other device which tells precise direction
