In flight mechanics and aviation, Pressure altitude refers to the altitude above the standard pressure level at which a specific atmospheric pressure is measured. The pressure altitude (hp​) is calculated using the following formula: Where: hp​ is the pressure altitude, h0​ is the elevation of the standard pressure level (m), P is the atmospheric pressure

In flight mechanics, the Reynolds number (Re) is a dimensionless quantity used to characterize the flow of air around an aircraft. It’s defined as the ratio of inertial forces to viscous forces in the airflow. The Reynolds number is crucial in determining whether the flow around an aircraft is laminar or turbulent and affects various

The rate of turn (ROT) from the turn radius in flight mechanics refers to the angular velocity at which an aircraft changes its heading while maintaining a constant altitude and airspeed. The formula indicates that the rate of turn is inversely proportional to the turn radius. In other words, smaller turn radii result in higher rates

In flight mechanics, the rate of turn (ROT) is the angular velocity at which an aircraft changes its heading while maintaining a constant altitude and airspeed. It quantifies how quickly the aircraft can execute a turn maneuver. The rate of turn is a crucial parameter in flight dynamics as it directly affects the aircraft’s maneuverability,

In flight mechanics, “corner velocity” refers to the airspeed at which an aircraft can execute a coordinated level turn without experiencing a stall. It represents the balance between the aircraft’s lift and its load factor during the turn, ensuring that the wing operates at the critical angle of attack without exceeding its maximum lift capability.

In flight mechanics, specific range is a measure of an aircraft’s efficiency in terms of the distance it can travel per unit of fuel consumed. It quantifies the aircraft’s ability to cover distance efficiently with the available fuel resources. A higher specific range value indicates greater fuel efficiency, allowing the aircraft to cover more distance

Specific endurance in flight mechanics refers to the measure of an aircraft’s ability to remain airborne for a given amount of fuel consumed. It quantifies the efficiency of fuel usage in relation to the aircraft’s endurance in flight. Specifically, it represents the duration an aircraft can fly per unit of fuel consumed. The formula to

The induced drag coefficient (CDi​​) quantifies the amount of induced drag per unit lift generated by an aircraft. It’s a dimensionless parameter that is often used in aerodynamic analyses to assess the efficiency of the aircraft’s wing design. A lower induced drag coefficient indicates a more efficient wing design in terms of minimizing induced drag
