Source Systems: Pitot-Static vs. Gyro
Flight instruments don't work in isolation. They rely on two primary systems: the **Pitot-Static System** (measuring air pressure) and the **Gyroscopic System** (powered by vacuum or electricity). Knowing which instrument belongs to which system is vital for troubleshooting in-flight failures.
Pitot-Static Group
Uses ram air and ambient air pressure. Includes ASI, Altimeter, and VSI.
Gyroscopic Group
Relies on spinning rotors (vacuum driven in C152). Includes AI, HI, and TC (Electrical).

Essential V-Speeds (Cessna 152)
These critical speeds are marked on the Airspeed Indicator by specific color arcs.
| Designation | Speed (KIAS) | Meaning | Indicator Color |

The Instrument Lab
Simulate flight conditions to see how the instruments react. Notice the relationship between Pitch, Airspeed, and Vertical Speed.
