Evaluate the given problem
Problem 1- Calculate the Total Energy (ft-lb) of an aircraft weighing 135,000 lbs at 10,000 ft true altitude and 180 KTS True Air Speed.
Problem 2- Calculate Vertical Velocity in ft/min and Ground Speed in knots for an aircraft in a 180 KTAS climb with a climb angle of 10 deg (assume no wind).
Problem 3- If stall speed in KTAS for an aircraft is 120 KTAS at sea level, what is the stall speed in KTAS (True Airspeed) of the aircraft at 10,000 ft Density altitude?
I need help to solve the above problem.
