An aircraft is operating with CL of 1.5 and has power required of 120W. If we want to reduce the power required by half then, find the value of CL at this power required condition. Consider steady level flight.

Performance and Flight Mechanics topics include: Steady level flight, steady climbing and descending flight, level turning and gliding flight, energy maneuverability methods, flight mechanics operating envelope, flight mechanics takeoff and landing analysis. Aircraft performance is a measure of how well an aircraft flies. It includes many factors such as:  Weight, Atmospheric conditions, Pressure, Temperature, Humidity, Runway at takeoff, Density altitude.  Aircraft performance can include: Speed Ceiling Range Fuel efficiency Take-off distance required Climb rate Aircraft...

Aircraft performance is a measure of how well an aircraft flies. It includes many factors such as:  Weight, Atmospheric conditions, Pressure, Temperature, Humidity, Runway at takeoff, Density altitude. 

Aircraft performance can include:
Speed
Ceiling
Range
Fuel efficiency
Take-off distance required
Climb rate
Aircraft controllability speeds 

Aircraft performance can be calculated using density altitude. As air density decreases, aircraft performance decreases. 

Flight mechanics of high-performance aircraft includes:
Equations of motion
Aerodynamic forces
Propulsion systems
Descent and glide performance
Cruise performance
Climb 

Flight mechanics can be divided into five broad areas:
Trajectory analysis (performance)
Stability and control
Aircraft sizing
Simulation
Flight testing
