I found it more convenient to edit the aircraft manually with a program like notepad++ as the powersettings needed to be re-ordered.

T‌he .aircraft file contains several lines of this form:
<CruiseProfile Name="2500ft/79%/25/2500, 140kts" FuelBurn="44.000000" IndicatedAirspeed="140.000000" Airspeed="140.000000" AirspeedType="True" />

T‌here are 2 items about airspeed showing the same value. What is the intention for this ?

I‌s there more information about the structure of the .aircraft file? Most entries are self explaining of course‌‌‌‌
