Using this incident as an example. One would have to look at the FDR, but let’s say they were below V1, but at a possible flying speed. Detecting the obstacle, an emergency system might reject the takeoff, but the Captain might have already decided to rotate early, clear the obstacle and stagger into the air.
Granted it puts the aircraft into a vulnerable position, should an engine (for example) fail. Second segment climb performance is now poorer. But …. the ground collision would have been avoided.
Looking at your example though: “it’s well established that no plane is supposed to be equipped with the tech to independently reject the takeoff”.
If the aircraft is below v1, is there any scenario where it has enough speed to become airborne?
Also, isn't 'try to struggle into the air" (aka, pull up in a desperate attempt to get the aircraft airborne before you should) the last thing a pilot should do? It could easily take an unfortunate but survivable crash (Lima) and turn it into an unsurvivable one (like Linate)
Not a pilot, would love to hear some thoughts from those who are.
