Aircraft Ground (EJet) – Breeze Practice Test

The hydraulic fluid used in EJet systems is typically red or green, depending on the specific type of fluid. This color coding is crucial for easy identification and maintenance. Red hydraulic fluid often indicates a specific formulation that is compatible with seals and components in the aircraft's hydraulic system. Green may designate a different type of hydraulic fluid that has properties suitable for various operational environments or temperature ranges.

Understanding the color coding of hydraulic fluids is essential for maintenance personnel to ensure that the correct fluid is used during repairs or when replenishing the system, thus preventing potential system failures due to incompatible fluid types.
