During turbine engine maintenance, which indicator is primarily tracked to ensure proper speed control?

Explanation:
Controlling turbine engine speed relies on the actual rotation rate of the engine. RPM gives the direct, overall measure of how fast the engine’s shafts are turning and shows whether the speed matches the commanded setting. If RPM is off, the fuel control system adjusts fuel flow to bring it back on target, or flags a fault. EGT reflects heat from combustion, which can vary with fuel and air but isn’t a direct indicator of speed. Oil pressure indicates lubrication health, not how fast the engine is spinning. N1 tracks the speed of a specific spool, which is useful for detailed performance analysis, but the fundamental indicator for ensuring proper speed control is the actual RPM.
