Calculators, Equations and other Stuff

Here are some links to Calculators, link to Equations and their derivation and links to pages that don't have a dedicated blog page yet or are more an addition to some pages than their own topic.


Calculators and Units Converters
A variety of calculators collected on one place.

Advanced Earth Curvature Calculator

Globe and Flat Earth Transformations and Mappings

Coriolis, Centrifugal and Gravitational Forces on the WGS84 Globe Model

(WGS84 Calculator)
For calculations in the WGS84 ellipsoid model of the earth

Earth Gravity Calculator
Calculates the effective gravitational acceleration, the pure gravitational acceleration and the centrifugal acceleration for any point on the Reference Ellipsoid or above.

Creating Flight Plans for Flat Earth
This App lets you create a Flight Plan based on the Flat Earth Model and view the calculated track on flat earth and globe.

Distances on Globe and Flat Earth
Calculate the shortest distance between two points for globe and flat earth.

Centrifugal and Gravitational Acceleration in an Aircraft
Calculation of the Eötvös effect on a weight in a aircraft, taking speed, direction, latitude and altitude into account.

Calculator: Parallax Triangles

Cavendish Experiment Simulator

Calculator for Refractivity based on Ciddor Equation

Communication Path Calculator (RF Link Budget)
This calculator determines the amount of transmitted power received and delivered to the input of a radio receiver in a RF communication link that has signal dissipation losses in the transmitter and receiver hardware as well as signal attenuation as the RF signal energy travels and disperses along its propagation path. The transmitted power received together with the receiver sensitivity determines if the communication link is successful or fails. Author George Hnatiuk.
