Consider the LTV Vought A$-7$ data indicated below for three flight conditions where $H$ denotes altitude and V denotes velocity. $($Introduction to Aircraft Flight Mechanics, T$.$ R$.$ Yechout, $2003).$ Also consider the pure rolling model indicated below.

${}^{}-L_{}{}^{}=L_{{}_A}{}_A$

with

$L_{{}^{}}=-\frac{4\mathrm{.}4011}{s},L_{{}_A}=+\frac{28\mathrm{.}461}{s^2}$ for $(H,V{)}_1=(00,000ft,670f\frac{t}{s})$

$L_{{}^{}}=-\frac{1\mathrm{.}2951}{s},L_{{}_A}=+\frac{7\mathrm{.}8591}{s^2}$ for $(H,V{)}_2=(35,000ft,584f\frac{t}{s})$

$L_{}=-\frac{2\mathrm{.}9561}{s},L_{{}_{}}=+\frac{14\mathrm{.}241}{s^2}$ for $(H,V{)}_3=(35,000ft,876f\frac{t}{s})$

a$)$ Compute decay rate $,$ time constant $,$ and amplitude $$ for an aileron step input ${}_{}=+3$ deg for flight condition condition $(H,V{)}_2.$

b$)$ Consider the A$-7$ and associated flight condition to be Class IV and Category B$.$ Use the table below to determine the roll dynamics flying quality level $($Introduction to Aircraft Flight Mechanics, T$.$ R$.$ Yechout, $2003)$ for flight condition $(H,V{)}_2.$
