Using the figure provided, answer the following: $\backslash (\backslash$quad C$\_\{$M$\}\backslash ).$

A$.$ Which line represents a stable airplane? Why?

B$.$ For the other two lines, what type of stability do they represent?

C$.$ For each line, explain how the airplane will initially react if disturbed from an equilibrium condition.

D$.$ Which lines show a trim condition?

E$.$ For each line, describe the location of the center of gravity and the neutral point relative to each other.

F $.$ The nondimensional cg locations for the three lines are given as $\backslash ($ h$\_\{$A$\}=0\mathrm{.}3,$ h$\_\{$B$\}=0\mathrm{.}65\backslash ),$ and $\backslash ($ h$\_\{$C$\}=0\mathrm{.}45\backslash ).$ Calculate the static margin for each line.

Figure: Plot of pitching moment about the center of gravity versus the angle of attack. Three lines are provided. The blue line, labeled $\backslash ($ A $\backslash ),$ has a negative slope that crosses the positive $\backslash ($ y $\backslash )$ axis and the positive $\backslash ($ x $\backslash )-$axis. The red line, labeled $\backslash ($ B $\backslash ),$ has a positive slope that crosses the negative $\backslash ($ y $\backslash )-$axis and the positive $\backslash ($ x $\backslash )-$axis. The green line, labeled $\backslash ($ C $\backslash ),$ has a slope of $0$ and is located below the horizontal axis.
