In the SOC there is software package that updates the Turbulence Plot Area based upon new meteorological information obtained from private companies or NWS. This software is designed so that it will examine all the currently active flight plans (airborne aircraft) to determine if a Turbulence Plot Alert should be issued.
Information Used in Flight Planning:
NWA uses all the information on the list, but was keen to point out that Weight & Balance comes personnel located in Memphis, as opposed to Load Planners that are a part of the Minneapolis-based SOC.
Meteorology  Forecast and current information on en route winds, temperature, 
turbulence, icing, and other phenomena 
Maintenance  Aircraft MEL and CDL status; aircraft routing; planned and required 
maintenance 
Crew Schedule  Crew training and qualification records; duty time and flight time limitations 
Load Planning  Departure and arrival runway, flap selections and allowable weight 
calculations; takeoff power settings; aircraft loading schedules, and 
constraints 
Aircraft Data  Tail number-unique fuel flow and fuel burn characteristics; performance 
capabilities and limitations 
Station Data  Availability of runways, gates, and ground equipment; fuel cost and 
availability; fuel tankering analysis 

Nav Data Database containing all FAA preferred and company routes, published
waypoints, airways, SIDs, and STARs Marketing On-time performance history and sensitivity per city-pair, i.e., to/from
hub; connecting passenger matrix and flight availability Flight Schedule Relational database linking all flights in the operating schedule; aircraft
routing, fuel tankering and delay analyses

Tasks Involved in Flight Planning:
There were two classes of tasks, important and support, identified for developing a flight plan at NWA:
Important (“attended to first”)
.  
Payload determination and coordination with load planners for weight and balance calculation

.  
Alternate airport determination

.  
Route selection

.  
Re-dispatch point determination for long range flights

.  
Aircraft minimum equipment verification

Supporting (“necessary to complete, not the first priority”)
.  
Speed and altitude profile calculation, and estimation of flight time

.  
En route alternate selection (as required)

.  
Fuel requirement calculation and coordination with fuel loaders

.  
Coordination of the flight plan with the pilot

.  
Flight plan filing with the FAA

Historical information is also taken into account when assigning aircraft type and estimating load capacity requirements. NWA takes into account the last 7 calendar days and the last 7 same-day-of-the-week (i.e., the last 7 Tuesdays) when estimating load/passenger capacity requirements.
