etold is a program that calculates the required performance data as specified in the Airplane Flight Manual (AFM) Performance Charts. As you change the configuration or conditions, the resulting data changes.

If internet access is available, the program also retrieves data about the airport (runway data, etc.) as well as weather data (TAF and METARs) for the desired airports from the website.

All data used in calculations can be overridden as desired. For instance, if you think that the temperature at the time of departure will be differnet from the current METAR, you can override the temperature that the program retrieved from the METAR.

The program attempts to parse the weather data from the METAR, however, if the METAR format is in error, the program may not be successful. In this case, the raw METAR is displayed so that you can interpret the various data needed for the calculations.
