The flight plan is generally determined on the ground, before departure either by the pilot for smaller aircraft or a professional dispatcher for airliners.
It is entered into the FMS either

by typing it in,
selecting it from a saved library of common routes (Company Routes) or
via an ACARS datalink with the airline dispatch center.
During preflight, other information relevant to managing the flight plan is entered.
This can include performance information such as
gross weight,
fuel weight and center of gravity
It will include altitudes including the initial cruise altitude.
For aircraft that do not have a GPS, the initial position is also required.
در هنگام Preflight سایر اطلاعات مربوط به مدیریت پرواز به FMS وارد می شود . برای مثال Gross weight یا وزن سوخت یا مرکز ثقل یا اطلاعات ارتفاع و برای هواپیماهایی که GPS ندارند ، مختصات مکان اولیه نیز وارد می شود.
The pilot uses the FMS to modify the flight plan in flight for a variety of reasons.
Significant engineering design minimizes the keystrokes in order to minimize pilot workload in flight and eliminate any confusing information (Hazardously Misleading Information).

The FMS also sends the flight plan information for display on the Navigation Display (ND) of the flight deck instruments Electronic Flight Instrument System (EFIS).
FMS همچنین اطلاعات پرواز را به واحد ND که خود مربوط به EFIS می باشد ، می فرستد.
The flight plan generally appears as a magenta line, with other airports, radio aids and waypoints displayed.

often for tactical requirements including search patterns,
rendezvous,
in-flight refueling tanker orbits,
calculated air release points (CARP) for accurate parachute jumps
are just a few of the special flight plans some FMS can calculate.
