Convenience problem as a cause of disaster
Everyone has heard the latest news about the crash of a passenger Boeing 737 in Perm on September 14. They say that the cause of the disaster could be the use on the liner of a non-standard flight navigation instrument called "artificial horizon".
Let's understand the essence of the problem.
Instruments of type "artificial horizon" (1) can be of two types of indication:
- From the ground to the plane (2)
- From the plane to the ground (3)
Obviously, it is quite difficult to rebuild the mind on a different type of device. In our case, the plane can turn left instead of turning right. And in a critical situation such an error can be made easily.
