When scheduling a new flight, one can see the usage percentage of every aircraft. The issue is that this percentage does not always correspond to the usage of the aircraft, leaving me with the impression that an aircraft is heavily used, while it can have very few scheduled flights.
In the screenshots I uploaded here, you may see that the aircraft named NAN14-ECO shows a usage rate of 98%, while its scheduled flights correspond to a rate of around 38%.
