Established in 1997, Durham Flight Centre or DFC has been training aspiring pilots for more than 15 years. Located in the Enterprise Airlines hanger building on the grounds of Oshawa Municipal Airport, DFC has earned the reputation of being a top notch flight school that charges fair prices for ground training, instructor time and plane rentals. Durham Flight Centre weight and balance calculator is specific to DFC planes. The app holds the current basic empty weight, arms and moments of each DFC plane. If the BEW or Moment for the plane changes, the app will be updated and distributed to the pilots who have the app on their device and the device is able to receive updates. Pilots will pick a DFC plane and enter in the weights(pounds) for the pilot, passengers, fuel (gallons) and baggage. The app then calculates the moments for each arm and verifies if you are within or out of limits for weight and center of gravity. If the Fuel Used (gallons) section is filled out then a landing weight and C of G is calculated for you. A simple colour code lets you know if you are within the weight and C of G limits. Green = within limits Yellow = outside of utility limits, but within normal limits (C172s) Red = outside limits Also set up your preferences for the app on the Settings menu, including storage of your weight to make entering in pilots weight automatic. Disclaimer: It is still the PIC's responsibility to make sure the aircraft is properly loaded.
