Flight Planning

Overview

Flying an airliner is usually done using IFR (Instrument Flight Rules). This means that you will be flying with an IFR flight plan. The IFR flight plan is usually created before the flight, and is then loaded into the aircraft's flight management system (FMS).

Flying IFR (Instrument Flight Rules) even in a simulation like Microsoft Flight Simulator always requires some level of flight planning.

In addition to the obvious route planning there are several other aspects which are critical to any good flight plan:

• Route Planning
• Origin and Destination
• Runways, SID and STAR
• Compliance with ATC Requirements
• Routing and Constraints
• Fuel Calculation
• Weather Forecast
• Wind Profiles
• Cost and Time Optimization

See Flight Planning on Wikipedia for more information.

Microsoft Flight Simulator tries to offer a simple way to do route planning (World Map before starting a flight) however this falls short, especially for users wanting a more realistic experience for airliner flying.

There are various ways to load a flight plan into the aircraft. In real life pilots usually use an external data link to load flight plans made for the flight by their company. Or they use the MCDU to enter a flight plan manually from their flight briefing documents.

As in real world aircraft it is common in flight simulation aircraft to integrate these systems directly with the aircraft's flight management system to be able to import all the relevant planning data. This includes the route, altitudes, constraints, fuel, payload (passengers, cargo), and other data points.

See MCDU F-PLN page for more information on the aircraft's flight planning in the Multipurpose Control and Display Unit (MCDU).

Loading a flight plan in the A32NX

In the A32NX for Microsoft Flight Simulator, we have these options to load a flight plan:

As Microsoft Flight Simulator uses a very simplified flight planning system, we have created our own custom FMS (Flight Management System) which is used in the A32NX. It is much closer to the FMS in the real aircraft and it understands and represents real world flight plans much more accurately.

A custom FMS on the other hand results in issues syncing the flight plan from the aircraft back into the simulator. Therefore, simulator-features as the MSFS ATC or the VFR Map will not always work as expected. Especially flight plans with complex routing may have significant issues if saved backwards or loaded externally through the simulator's simplified flight planning.

This is a general issue for all realistic and complex airliners in Microsoft Flight Simulator and unless the simulator's built-in flight planner and ATC is significantly improved this will always cause problems with realistic airliners.

MSFS World Map Flight Planning, ATC and VFR Map

Depending on how you want to use the A32NX in combination with the MSFS' World Map Planning, ATC and VFR Map, you can choose between different methods to load a flight plan into the A32NX:

See Setting Sync MSFS Flight Plan for more information.

Not Using MSFS World Map, MSFS ATC or MSFS VFR Map

We recommend to use our built-in integration with SimBrief for flight planning. This will allow you to directly import flight plans from SimBrief into the MCDU.

See our SimBrief Integration Guide for more information.

As long as MSFS ATC and VFR Map are not required, the aircraft's flight plan does not have to be synchronized back to the MSFS flight planner (set flyPad's Setting > Sim Options > Sync MSFS Flight Plan to None).

The MSFS ATC and VFR Map will not be aware of the flight plan at all and cannot be used.

Using the MSFS World Map Flight Planner to Create and Load a Flight Plan

If you want to use the MSFS World Map Flight Planner to build and load a flight plan, you need to set the Sync MSFS Flight Plan option in the flyPad's Setting > Sim Options > Sync MSFS Flight Plan to Load Only.

This ensures the MSFS flight plan is loaded into the aircraft's flight plan when starting the flight.

Any changes made to the flight plan in the MCDU will not be saved back to the MSFS flight plan. This means the MSFS ATC and VFR Map will not be aware of these changes.

Using the MSFS World Map Flight Planner and MSFS ATC

If you are using the MSFS Flight Planner to build and load a flight plan, and you also want to use the MSFS ATC even after making changes to the aircraft's flight plan, you need to set the flyPad's Setting > Sim Options > Sync MSFS Flight Plan option to Save.

With this setting the aircraft will attempt to save any changes to the flight plan made in the MCDU back to the simulator's flight plan. This will not always work as expected and may result in issues with the MSFS ATC. See the warning below for more information.

Importing a SimBrief Flight Plan and Using MSFS ATC

If you are using the aircraft's built-in SimBrief integration to import a flight plan, and you also want to use the MSFS ATC you need to set the flyPad's Setting > Sim Options > Sync MSFS Flight Plan option to Save.

When importing a flight plan from SimBrief into the MCDU, do not select a destination airport and do not build a flight plan using the MSFS World Planner.

With this setting the aircraft attempts to save the loaded SimBrief flight plan and any subsequent changes to the flight plan made in the MCDU back to the simulator's flight plan. This will not always work as expected and may result in issues with the MSFS ATC. See the warning below for more information.
