In CLAP, what does the letter P represent?

• A. Pitch rate
• B. Pitch angle
• C. Power output
• D. Pitch damper

Answer: (A)

In CLAP, the P parameter represents how fast the rotor blade pitch is changing—the pitch rate. This is about the dynamic command to adjust blade pitch, not the actual pitch angle at a given moment or the engine’s power output. Pitch rate is what governs how quickly the rotor responds to a command, affecting transient behavior, stability, and potential overshoot. That’s why the correct interpretation is pitch rate: it focuses on the speed of the pitch change rather than the blade’s current angle, the engine power, or any damping mechanism.
