These Air Safety Institute productions are wonderful, if often harrowing, learning resources. This video concerns the cockpit emergency known as “partial panel.” This means that some of the instruments are no longer operative or reliable, so the pilot has to identify which instruments aren’t working, and then navigate with the information he or she can glean from the working instruments.
One of my takeaways from this video is that I should practice using the magnetic compass. The magnetic compass is the most reliable instrument in the cockpit, but under normal circumstances it is only consulted to make corrections to the gyroscope-driven heading indicator. But I should really practice using the compass to make turns and hold heading.
