'''Flight plans''' are documents filed by a [[aviator|pilot]] or [[flight dispatcher]] with the local [[Air Navigation Service Provider]] (e.g., the [[Federal Aviation Administration|FAA]] in the United States) prior to departure which indicate the plane's planned route or [[flight path]].<ref>{{cite book|title=A Dictionary of Aviation |first=David W. |last=Wragg |isbn=0-85045-163-9 |publisher=Frederick Fell, Inc. |publication-place=New York |date=1974 |edition=1st American |page=133}}</ref> Flight plan format is specified in ICAO Doc 4444. They generally include basic information such as departure and arrival points, estimated time en route, alternate airports in case of bad weather, type of flight (whether [[instrument flight rules]] [IFR] or [[visual flight rules]] [VFR]), the pilot's information, number of people on board, and information about the aircraft itself. In most countries, flight plans are required for flights under IFR, but may be optional for flying VFR unless crossing international borders. Flight plans are highly recommended, especially when flying over inhospitable areas such as water, as they provide a way of alerting rescuers if the flight is overdue. In the United States and Canada, when an aircraft is crossing the [[Air Defense Identification Zone (North America)|Air Defense Identification Zone]] (ADIZ), either an IFR or a special type of VFR flight plan called a DVFR (Defense VFR) flight plan must be filed. For IFR flights, flight plans are used by [[air traffic control]] to initiate tracking and routing services. For VFR flights, their only purpose is to provide needed information should search and rescue operations be required, or for use by air traffic control when flying in a "Special Flight Rules Area."
