Flight and Navigation Calculators

• 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.
• Air Speed from Pressures: It uses the Bernoulli Equation to estimate air speed based on the total Pressure measured by a pilot tube, total Static local atmospheric pressure and the Density of Air.
