Engineers evaluating an AH$-64$ Apache helicopter have decided on a new location to place the pitot$-$static system.$$ Test pilots at $9500$ ft above sea level report that the static port registers a pressure of $10\mathrm{.}30$ psi and the pitot tube registers a pressure of $10\mathrm{.}52$ psi.$$ telemetry data indicate that the aircraft is flying at $110$ knots $(185\mathrm{.}7$ ft$/$s$).$ assuming the density of air at $9500$ ft is $0\mathrm{.}001785$ slug$/$ft$3$ determine:

$($a$)$ the indicated airspeed $[$ft$/$s$]$ calculated using the pitot$-$static system

$($b$)$ is the pitot$-$static system accurate $($within $+/-5$ knots of the telemetry data$)?$
