Summary

An illustrative opening-area calculation using a published example coefficient and vent area. Based on Van Rossum (2027), §6.8, and Cooper (2002), p. 3-228.

Original illustration for Aerodynamic free area, level 3 Advanced.

Source basis: Van Rossum (2027), §6.8; Cooper (2002), p. 3-228. Create an original visual; redraw, do not copy source figures.
Alt text: Calculation cards showing 1.5 square metres multiplied by 0.65 to give 0.975 square metres.
Accuracy notes: Do not label these values as a tested hatch specification. Preserve the distinction between geometric and aerodynamic area.
