/*
 * Extra Times - These line edits should be filled out automatically,

 * manual adjustments are possible to cater for situations where for
 * example one portion of the flight is logged under different rules
 * than the rest of it.
 *
 * For example,
 * if we know the aircraft details we can determine how to log these times.
 * Some times are mutually exclusive, others can be combined.
 *
 * For example,
 * for a commercial Passenger flight, the commander can log all time as
 * Total Time and PIC time. If the aircraft is a multi-engine jet he can
 * also log Multi-Pilot time, and if he is an instructor, instructor time.
 *
 * It is not possible, however to log flight time as VFR or IFR time
 * simultaneously, as a flight at any given point in time can only follow
 * one set of rules. It is possible, to change flight rules and log the first
 * x minutes as VFR and the rest of it as IFR, for example. Hence the need
 * for the possibility to edit these times manually.
 *
 * The most complex time to determine is night time, see documentation of
 * the calc class for details.
 *
 * In General, the idea is to automatically fill as much as possible, but
 * if the user decides to change these times, accept the inputs, as long as
 * they are generally valid. We cannot cater for all possibilities, so as long
 * as the time the user has put in is a valid time <= Total Time, it can be
 * accepted to the database.
