You can configure: Persons on board Cylinders The envelope Basket and burner Meteo information Temperature in celsius or fahrenheit Weight in kg or pounds (lb) Tank volume in liters, US-gallons or UK-gallons Envelope volume in cubic meters or cubic feet Eltitude in meters or feet Metar info can be retrieved automatically for an given airfield to: Retrieve actual ground temperature Retermine actual field elevation * Retrieve current QNH All configuration data is kept locally on your iPhone or iPad. Multiple balloon configurations can be stored. Envelope volumes can be entered in cubic meters or in cubic feet. The app determines automatically if cubic meters or cubic feet are used based on the entered value. For values greater than 1000, cubic meters are assumed, cubic feet (in thousands) for values less than 1000. Note: When all automatic options are selected the following steps are taken to retrieve meteorological and field information: Search for the nearest airport that provides a Metar report Using the retrieved Metar get the QNH and temperature. When your phone contains a barometer field elevation is determined The retrieved values are then used to perform the load calculation In some cases you may not want all options selected. If you are for example preparing your flight at noon you may want to enter the ground temperature manually because it will differ when you are flying in the evening. This app was made by balloon pilots for balloon pilots.
