Why don't I see any data displayed?
This could be for a couple of reasons:
You need to have flights logged with either scheduled or actual times. This is necessary for the feature to know how many segments are within the Flight Duty Period.
You need to have FDP times logged.
Does my Home Base get set for all flights?
After setting your Home Base, that location will remain the same until manually changed again. Be sure to reset your Home Base if necessary.
