1. What is Parachute Wing Loading?

Definition: Wing loading is the measurement of how much weight a parachute must support per unit area.

Purpose: It helps skydivers and parachute designers determine the appropriate parachute size for a given weight.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( WL \) — Wing loading (kg/m²)
• \( W \) — Total weight (kg)
• \( A \) — Parachute area (m²)

Explanation: The total weight is divided by the parachute's surface area to determine the pressure exerted on the parachute.

3. Importance of Wing Loading Calculation

Details: Proper wing loading calculation ensures safe descent rates, optimal parachute performance, and prevents excessive stress on the parachute.

4. Using the Calculator

Tips: Enter the total weight in kilograms and the parachute area in square meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical wing loading for skydiving?
A: For student skydivers, it's typically 0.5-0.8 kg/m². Experienced jumpers may use 1.0-1.5 kg/m² for faster descent.

Q2: How does wing loading affect descent rate?
A: Higher wing loading results in faster descent rates, while lower wing loading results in slower descent.

Q3: What's included in the total weight calculation?
A: Include the jumper's weight plus all gear (parachute, harness, container, etc.).

Q4: How do I measure parachute area?
A: The area is typically provided by the manufacturer. For round parachutes, it's the nominal diameter.

Q5: What are the safety considerations?
A: Too high wing loading can cause dangerous descent rates, while too low can make the parachute unstable.
