The aircraft performance database uses TAS for cruise and maximum speed (as can be confirmed by cross-referencing e.g. https://contentzone.eurocontrol.int/aircraftperformance/details.aspx?ICAO=A320). Therefore, the struct fields in AircraftPerformance have been renamed to reflect that, and usage of them now goes through new IASToTAS and TASToIAS functions.
Those functions are now based on the proper barometric formula to compute relative air densities at the current altitude.
