don't the planes know where the other is based on the fact that the tcas is yelling at them in the first place? easy enough to tell them to pull up if it knows

don't the planes know where the other is based on the fact that the tcas is yelling at them in the first place? easy enough to tell them to pull up if it knows they are below them.
- unsnap_biceps 2y agoCertainly the one plane is aware of the other, however, I wonder if the algorithm takes into account the physical characteristics of the planes. For example, a 737 descending would take longer to pull up on and there would be a period of time where the engine are spooling up that it continues to descend before it gains altitude. Would it be smart enough to figure out that the 737 is going to end up below it before gaining altitude and thus should actually descend faster? Does it just go, that plane is blow me, so pull up? It's a fascinating problem to think about the different edge cases and how it could possible handle it.
- weaksauce 2y agoyeah the system is constantly calculating velocities and positions in 3d space. there's a traffic advisory portion where it tells the pilots to be aware of traffic nearby and there's a resolution advisory which tells the pilots exactly what to do and at what rate. commercial pilots practice that in the sim extensively. the faa made having ads-b out mandatory for all aircraft some time ago which helps the planes see each other so the commercial one knew exactly where the smaller plane was.
