Question $4$a

The graph at left illustrates the Coefficient of lift vs angle of attack for $$ particular aircraft.

The aircraft weighs $25,000$ pounds.

The planform area of the aircraft wings is $237$ square feet.

The density altitude is $26,000$ feet.

The True Airspeed of the aircraft is $300\mathrm{.}0$ knots.

The aircraft is travelling at a contant speed with zero acceleration.

What is the angle of attack for this aircraft?

Question $4$b

What is the stall speed for the aircraft described in question $4$ a $?$

Question $4$c

If the aircraft in question $4$ a burns $3505$ lbs of fuel during flight, what is the new stall speed?

Question $4$d

The aircraft in question $4$a has burned $4000$ lbs of fuel during flight.

Due to turbulence, the aircraft experiences a sudden accelration of $1\mathrm{.}15G.$

What is the stall speed of this aircraft while experiencing this acceleration?
