What are the three categories of emergencies?

The main idea is that emergencies are grouped by what critical capability has failed: communications, navigation, or other aircraft systems. If you can’t communicate with ATC, that’s a communications emergency. If the navigation aids you rely on—like VOR, DME, ILS, or GPS—aren’t available, that’s a NAVAID emergency. If there’s a fault with systems not covered by the first two categories—such as electrical, hydraulics, flight controls, or other essential subsystems—it's categorized as other system failures. Weather and fuel issues can cause dangerous situations, but they aren’t the formal three-category breakdown used here, so the option listing communications failures, NAVAID failures, and other system failures best fits the standard classification.
