1. What is RC Wing Loading?

Definition: Wing loading is the measurement of an aircraft's weight divided by its wing area.

Purpose: It helps RC aircraft designers and pilots understand the aircraft's performance characteristics including stall speed, maneuverability, and landing speed.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The aircraft weight is divided by the wing area to determine how much weight each square meter of wing must support.

3. Importance of Wing Loading

Details: Lower wing loading generally means slower flight and better maneuverability, while higher wing loading means faster flight but requires more speed for takeoff and landing.

4. Using the Calculator

Tips: Enter the aircraft weight in kilograms and wing area in square meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical wing loading for RC planes?
A: It varies by type: Trainers 30-50 kg/m², Sport planes 50-80 kg/m², Jets 80-150 kg/m².

Q2: How does wing loading affect flight characteristics?
A: Higher wing loading means higher stall speed and less float, while lower wing loading allows slower flight and better thermal soaring.

Q3: How do I measure wing area?
A: For rectangular wings: span × chord. For tapered wings: average chord × span.

Q4: Should I include battery weight?
A: Yes, always use the total flying weight including battery, fuel (if applicable), and all equipment.

Q5: What's the relationship between wing loading and wing cube loading?
A: Wing cube loading (WCL) further refines the calculation by accounting for scale effects, calculated as weight/wing area^1.5.
