  1.  @Hans-gb4mv  Yes, you can have different states for different systems, even on the same data. Have RIMCAS treat an airplane as securely airborne only when his speed exceeds his highest V1 speed of his type, and have TCAS treat a plane to be possibly airborne whenever it exceeds his lowest possible V1 speed or maybe even 100 knots. Yes, this shows some planes to be possibly airborne AND possibly not airborne, but this must be accepted because its not wrong and its safety critical. Now and when some ATC controllers stop listening to RIMCAS there must be researched a different way to reduce false warnings. Just doing nothing isn't the way the aviation business is working. Otherwise, collision avoidance is guaranteed through the pilots visual separation in this case, so no real thread here.

  2.  @c00l00k  That's right and that wasn't clearly mentioned in the video, the thread avoidance is guaranteed through the pilot applied visual separation.

  3. That is true. But there is also another possible resolutions to this without having such a system. Safety critical transmissions must be read back, in this case the Embrearor failed to repeat their rejected takeoff message.

  4. I think they did took that possibility into consideration, by allowing the second plane to only takeoff with visual separation.

  5.  @Argosh  All what you wrote is known to me, including Überlingen, so maybe you didn't understood what I wrote.

  6.  @skyhawk_4526  That is true.

  7.  @docteurgreene  No it didn't failed, the second plane deliberately stopped and didn't crashed. It was only cleared to takeoff by "pilot visual separation", which is only allowed in good weather.

  8.  @docteurgreene  A pilot panicking is never an excuse. You also wouldn't run a small bakery by a politician.

  9. What is very important, the Tenerife Airport disaster was fundamentally different. There was no good weather and therefor no pilot applied visual separation rules and therefor the then mentioned errors caused the crash. Here we had the pilot applied visual separation rules which are only allowed on good weather. And those rules did avoided an accident here.

  10.  @Argosh  You are arguing against things I didn't wrote. You are provoking. I don't see any point in answering you.
