In flight mechanics, pressure refers to the force applied per unit area by the surrounding air onto an aircraft’s surfaces. This vital parameter influences aerodynamic forces and is affected by factors such as altitude, airspeed, and temperature. The formula to calculate pressure as follows: Where: ρ is the density in kg/m3. R is the specific […]

Average dynamic pressure refers to the mean kinetic energy per unit area experienced by an aircraft due to its motion through the air. It is a measure of the pressure exerted by the fluid due to its motion. It characterizes the pressure exerted by the airflow due to its motion and is a critical parameter

The average Mach number in flight mechanics represents the ratio of an aircraft’s average true airspeed to the speed of sound in the surrounding air. It is a dimensionless parameter crucial for characterizing an aircraft’s speed, particularly in high-speed and supersonic flight regimes. The formula to calculate average Mach Number as follows: Where: Vavg is

Average velocity in flight mechanics refers to the overall motion of an aircraft over a specific period of time. It is defined as the total displacement of the aircraft divided by the total time taken. This concept provides a measure of the average speed and direction of the aircraft during that time interval, offering insights

Indicated airspeed (IAS) is the measure of an aircraft’s speed relative to the air around it as displayed on the airspeed indicator. It is a crucial parameter for pilots, providing real-time information on the aircraft’s velocity during flight. The formula to calculate Indicated airspeed (IAS) as follows:  Where: Vc is the Calibrated airspeed (CAS) in

True Airspeed (TAS) in flight mechanics is the actual speed of an aircraft through the air, accounting for variations in air density due to changes in altitude and temperature. It represents the velocity relative to the surrounding air mass, providing a more accurate measure than Indicated Airspeed (IAS). Pilots use correction factors to convert IAS

In flight mechanics, the pressure correction factor is a parameter used to adjust indicated airspeed readings for variations in atmospheric pressure. It compensates for the impact of changing air density with altitude, providing a corrected airspeed known as calibrated airspeed. This correction ensures more accurate airspeed measurements, critical for precise aircraft performance and navigation, especially

Equivalent Airspeed (EAS) in flight mechanics refers to the calibrated airspeed corrected for compressibility effects. It represents the airspeed at sea level that would result in the same dynamic pressure as the true airspeed at a given altitude. EAS is a valuable parameter for aircraft performance calculations and flight testing, allowing for a more accurate

The dynamic pressure ratio refers to the comparison of dynamic pressures at two specific points in the airflow around an aircraft. The dynamic pressure ratio is a dimensionless parameter that characterizes the relative change in dynamic pressure between two locations in the airflow. The formula to calculate Dynamic pressure ratio as follows: Where: qh is

The horizontal tail angle of attack in flight mechanics refers to the angle between the chord line of the horizontal tail surfaces and the oncoming airflow. This angle is critical for the aerodynamic performance and stability of the aircraft. The horizontal tail angle of attack is typically set to contribute to the overall stability and
