Many critical gyroscopic flight instruments, particularly air- or vacuum-driven ones, are prone to mechanical failure (e.g., vacuum pump), which can lead to instrument disagreement. Such failures ...

Initial flight training emphasizes trusting instruments over senses to overcome spatial disorientation, especially in low visibility conditions. However, during night takeoffs, the gyro-based attitude ...

Aviation instruments are highly interesting pieces of engineering, and it is quite satisfying to watch the often over-engineered mechanisms behind them. If you are into that sort of thing it is ...
