I read a news item recently . According to it, of two airplanes, one of the aeroplanes an A-320 (VT-IFP) (dunno what VT-IFP stands for) got damaged sharklet -portion curved at the tip of aircraft wing which was observed and then shared with the aircraft staff (stewards I guess) who informed the captain and the plane was led to a hangar, passengers de-boarded and sent on other plane/s by the airline.

What I want to know is: aren't there any sensors which can detect an impact and give/share that information to the pilot? I do understand that the airplane takes a lot of jerk and movement during takeoff, landing as well as during turbulence.

But when damage as such as the one described above happens, there should be some automated systems that should inform the pilot instead of having to rely on a passenger's keen eyes.
