The altimeter is a crucial instrument in aircraft that measures the altitude. However, flight safety also depends on external factors that we sometimes may not be able to immediately understand and control.
Modern altimeter malfunction example:
Test flights of F-16's has been conducted in Israel, where F-16's were doing a "nap-of-earth" flights at the border to avoid detection. On approach to the Dead Sea, the entire navigation system were suddenly failing. The ground tests went perfectly, but every time it went airborne the system kept rebooting, which created an extremely dangerous condition for the pilot. Since the height of the Dead Sea is significantly below the world sea level, as soon as the F-16 reached the sea level, the Navcom was performing a division by zero, causing the software to constantly crash and reset.
