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 one of the major carriers, see Figure 5:
Select Destination
Important (“attended to first”)
.  
Payload
determination
and coordination
with load
planners for

calculation

.  
Alternate airport
determination

.  
Route selection

.  
Re-dispatch

equipment
verification

 

Figure 5. Tasks involved with flight planning (Airline)

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. One of the major carriers 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.
The other major carrier listed the key activities in flight planning, although not in any particular order as:
1.
Route construction

2.
Route initialization

3.
Access Upper Air weather

4.
Payload input

5.
Release calculation

6.
ATC Filing

The carrier listed the following as rules that are FARs attended to when flight planning:
1.
Fuel requirements - Destination weather, alternate criteria, etc.

2.
Terrain clearance / Depressurization

3.
Route construction - Airways vs. Direct segments vs. LAT / LONG.

4.
FAA Pref Routes / NRP Route requirements

5.
Communication / Navigation system requirements
