**Correction Angle**: Computes the navigation angle/azimuth correction angle using the wind speed, wind direction, flight heading and an Air Speed.**Ground Speed:**Computes the ground speed based on the wind speed, wind direction, a Flight Heading and an Air Speed.**Haversine - Distance**: Computes the distance between two points on a spherical model of the Earth along a great circle arc. This also includes the rhumb line distance and azimuth for the rhumb line.**Travel Time between Coordinates**: Computes the time to travel between to points on the globe in a great circle arc at an average velocity.**Distance to Sea Level Horizon at Altitude**: Computes the distance to the horizon from a specified height using a spherical model the mean spherical radius of the Earth**Force of Drag**: Calculates the resisting force of drag on an object flowing through a medium (e.g. air).**Force of Lift**: Computes the lifting force on the surface area of a wing based on the wing surface area, air flow velocity, density of air and a lift coefficient.**Lift Coefficient**: Compute the lift coefficient of a wing based on lift force, wing surface area, wind speed and density of air.**Velocity Needed for Takeoff**: Computes the velocity required to create more lift than the weight of an aircraft or watercraft using a wing (e.g. hydrofoil).**Glide Ratio**: Computes the glide ratio based on the change in forward distance and the change in altitude.**Wing Surface Area**: Computes the wing surface area required to achieve lift, base on a lift coefficient, lift force, wind speed and density of air.**Velocity of Air over the Wing**: Computes the velocity required to achieve a lift, based on lift coefficient, lift force, wing surface area and density of air.
