Selection of Wing Loading based on Range (R) Calculator

The selection of wing loading based on range ($W/S$) is an important aspect of aircraft design, particularly when optimizing an aircraft for a specific range performance. Wing loading is the ratio of an aircraft’s weight (W) to its wing’s reference area ($S$) and is typically expressed in pounds per square foot (psf) or newtons per square meter (N/m²).

To optimize wing loading for range, you can use the following formula:

•  $W/S$ is the wing loading (typically in psf or N/m²).
• $W$ is the aircraft’s weight (in pounds or newtons).
• $S$ is the wing’s reference area (in square feet or square meters)
