The NACA 4-digit airfoil series code designates maximum camber in % chord with its first digit, location of maximum camber in tenths of chord with its second digit, and maximum thickness with its last two digits. So, if a NACA 2415 airfoil has a 10-meter chord, calculate its maximum thickness in meters by multiplying the chord length by 15% thickness...
a) 1.5 m
b) 1.0 m
c) 0.5 m
d) 2.5 m
