| Jul 7, 2014 at 13:48 | comment | added | casey | @paul that's not really true. Many cockpits have great FOV though seeing directly down or above+behind can be problematic. At altitude visibility can be tremendous and you can sometimes see planes at quite a distance. Of course it helps if the sun is reflecting off the other airplane or that airplane is seeding a contrail. That gives decent time to react and even if you cant see you an listen to the TCAS which gives ample warning of a potential conflict (TA) before giving a direct command needing immediate reaction (RA). | |

Plus, it only take a few feet to avoid a collision. See and avoid is still an important process no matter how much technology there is out there. | |
