1 Introduction
Inflight Revision
This topic will provide a step-by-step walk-through of the inflight functions, and the best practices for quick execution of a revision.
We estimate that this will take 7 minutes to complete.
2 Detailed Explanation
Inflight Revisions
This module
demonstrates the methods for completing an inflight revision
with N-Flight Planning.
Inflight
Revisions can be used for many purposes. In this module, we
will review a simple inflight recalculation with no changes to the
flight. This can be used to provide burn figures for updated winds or
to provide an updated calculation for actual fuel figures
enroute.
We will review the process for an
inflight calcuation with flight plan changes, in this example a
diversion to a new airport.
In each case,
the demonstration assumes the flight has already been
successfully released. For basic flight planning actions, please
review the Plan Screen functionality modules.
Inflight
functionality in the presence of a Reclear is covered in
another module.
Click
the Progress menu
item.
After departure time, the N-Flight Planning system will estimate the progress of the flight via the Progress Screen. The Progress Screen can be updated with position report information manually by the user or automatically from the aircraft via ACARS integration.
Click
the Plan menu
item.
Planned information comes from the flight plan.
Actual information can be entered manually or ingested automatically via ACARS.
We will use waypoint KP15A for this inflight calculation.
Click
the Flight Info Waypoint green
arrow button.
Click
the Inflight list
item.
Click
the Waypoint dropdown
button.
Waypoints from the
planned route can be selected from the drop down list.
Ad hoc
waypoints can be typed into the Waypoint field.
Click
the KP15A list
item.
Click
the FOB input
field.
After a waypoint is selected, the system will automatically populate the "Expected" Flight Level, Time, Fuel on Board, and Actual Zero Fuel Weight for that waypoint.
We will update this waypoint with an "Actual" fuel value and recompute.
Enter 30500 into
the FOB field.
Click
the Compute button.
The updated fuel block information can now be communicated to the crew as necessary.
Inflight Revisions
We will now accomplish an inflight revision for diversion purposes.
Click
the Waypoint green arrow button.
Click
the Inflight list
item.
Click
the Waypoint dropdown
button.
Click
the KP06K list
item.
Click
the Dest input
field.
When the destination remains the same, the system will keep the originally planned route of flight.
Enter ord into
the Dest field.
If the destination is changed, a new route will have to be generated.
Click
the FOB input
field.
We will update the fuel on board, in addition to changing the destination.
Enter 21500 into
the FOB field.
Click
the Route menu
item.
After the destination is updated, the route group shows that there are no available routes for this flight plan.
Click
the New button.
Click
the Generate button.
First, we will generate a route using the MTTA functionality.
Click
the New button.
Click
the REV WPT input
field.
We will generate a second route, using "MTT" functionality which will allow for a more direct, non-airway, route.
Press
the 
key.
Click
the Generate button.
Click
the Apply button.
Click
the Compute button.
This updated fuel and routing information can be sent to the crew as necessary.
