If at each time the strobe light is flashing the stick is at full nose up position but when in the dark it is at full nose down then something of interest will show up on the elevator trace.
Animation is a wonderful tool for both pilots and investigatory bodies.
PJ2, you still do not produce any reason why the pilots should not get their data at the same time the manufacturer and the investigatory authority put their hands on them ... ?
