Deferred Maintenance Items

Not every plane flying is in perfect repair, though the airlines are very careful to take the problems into account. For example, when a plane takes off, the front wheel is spinning. If the special brake to stop it in during takeoff is not working, then the wheel cannot be retracted until it slows down on its own. If it is retracted while it is still spinning the heat of the rotation may damage the wheel or the housing. The plane can still fly, but it cannot carry quite as much weight during take off as it could if the wheel could be retracted earlier.

Needless to say, airlines like to avoid deferred maintenance items, but sometimes it is better to unload a few bags rather than cancel a flight and throw the whole system into a tizzy.
