How do you know if two planes are the same?
How do you know if two planes are the same? If the normal vectors are parallel, the two planes are either identical or parallel. If the normal vectors are not parallel, then the two planes meet and make a line of intersection, which is the set of points that are on both planes.
Can planes detect other planes?
Each aircraft broadcasts messages, which include altitude, and listens for messages from other aircraft. If TCAS receives messages from another aircraft nearby that operates at the same altitude, it warns the pilots and advises them to climb or descend.
Can 2 planes collide mid air?
A mid-air collision is a rare occurrence, but there are some elements that tend to be found in the majority of mid-air collisions. Contrary to what many people assume about mid-air collisions, these tragic crashes do not often happen in foggy weather or at night when visibility is impaired.
Can pilots see other planes at night?
The answer is quite simple, no, they don't actually see anything at night. Before takeoff, pilots scan the sky to avoid hazards and prevent compromising the entire flight.
