S=16.165;//wingarea(m^2)
AR=b^2/S;//aspect ratio
D=1.225;//density at sea level(Kg/m^3)
W=13127.5;//normal gross weight(N)
f=65;//fuel capacity
P=230;//power provided by piston engine (unit-horsepower(hp))
Sf=2.0025;//specific fuel consumption(N/(hp.h))
Cdo=0.025;//parasite drag coefficient
e=0.8;//oswald efficiency factor
