BCF Calc app for iPhone and iPad

This application is developed in order to reduce the risk of pilots and loaders double counting fuel and in turn increase the accuracy of manual weight and balance calculations. The hope of this application is to reduce the probability of tail strikes and other events caused by overloading fuel. It should be noted that this application is developed as a reference tool only. All errors in user input will prompt a message on the Calculated Fuel Quantities page saying "ERROR" in all sections except the ZFW will say the BCF is greater than the auxiliary fuel. Basic Functionality is as follows: total fuel on board is the sum of all fuel tanks (excluding the BCF), the ZFW is the BCF. Usable auxiliary tank is equal to the aux tank minus the ZFW. The total usable fuel is the total fuel on board minus the ZFW.
