1. What is Stick Deflection Angle?

Stick Deflection Angle is the angle made by the control stick (used to move control surface) of an aircraft with the vertical. It represents the physical input from the pilot to control the aircraft's attitude and movement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \delta_s \) — Stick Deflection Angle (rad)
• \( \delta_e \) — Elevator Deflection Angle (rad)
• \( L_s \) — Stick Length (m)
• \( G \) — Gearing Ratio (1/m)

Explanation: This formula calculates the stick deflection angle based on the elevator deflection, stick length, and the mechanical gearing ratio of the control system.

3. Importance of Stick Deflection Angle Calculation

Details: Accurate calculation of stick deflection angle is crucial for aircraft control system design, pilot control input analysis, and ensuring proper control surface response to pilot commands.

4. Using the Calculator

Tips: Enter elevator deflection angle in radians, stick length in meters, and gearing ratio in 1/m. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between stick deflection and elevator deflection?
A: The stick deflection angle determines how much the elevator will deflect, with the gearing ratio and stick length acting as mechanical multipliers in the control system.

Q2: Why is gearing ratio important in aircraft control systems?
A: Gearing ratio determines the mechanical advantage in the control system, affecting how much force the pilot needs to apply and how sensitive the control response will be.

Q3: What are typical values for stick length in aircraft?
A: Stick length varies by aircraft type but typically ranges from 0.2 to 0.5 meters in most general aviation and commercial aircraft.

Q4: How does stick deflection affect aircraft control?
A: Stick deflection directly controls the aircraft's pitch attitude through elevator deflection, affecting climb, descent, and overall aircraft maneuverability.

Q5: Are there limitations to this calculation?
A: This calculation assumes ideal mechanical linkage and doesn't account for control system friction, free play, or aerodynamic forces feedback.
