Power Required From Density At Sea Level Calculator

Power Required is the engine power needed for an aircraft to counter aerodynamic drag and maintain level flight at a specific velocity. This concept is crucial in aviation and aerodynamics to understand the energy needed to sustain flight under specific atmospheric conditions. The formula to calculate Power required at Sea level as follows:

Where:

• P_req​ is the power required (in watts),
• $W$ is the weight of the aircraft (in N),
• C_D​ is the drag coefficient,
• $S$ is the reference area (in square meters, m²),
• C_L​ is the lift coefficient,
• ρ₀​ is the standard air density at sea level (in kg/m³).
