What is NAVsystem?

NAVsystem is a software solution for flight planning and preparing flight briefings (PDF packages).
Our solution fits a wide range of operations, whether for scheduled carriers, charter airlines, cargo carriers, military and business jet operators.

An integral part of NAVsystem includes tools for route construction, calculating and compiling OFP, ATC FPL management and creating the PDF briefing.

NAVsystem consists of two main parts. The first part is a desktop application for dispatchers for Windows that allows you quick and easy flight planning.
The second part is a web briefing for creating and picking up flight briefing packs.

System can be set up in MacOS enviroment as well – using Parallels Desktop.

NAVsystem functions


Autorouter quickly finds a suitable route for your flight and makes a preliminary calculation of fuel, time and costs, including overflight charges.

It is possible to specify the conditions for your search by specifying points and parts of the route and it is also possible to disable points and parts of the route or FIR/UIR.
Eurocontrol RAD/CDR/DCT and CPLC restrictions are taken into consideration when searching for the route and the result is automatically validated by the Eurocontrol systems.

Autorouter uses an advanced algorithm to find the optimal route using the current forecasts of upper wind and temperature.
Together with the results of Autorouter, routes are also offered from a database of completed flights (more than 4 million routes) and also routes proposed by Eurocontrol.

You can easily search for a route with current NAT tracks, choose ETOPS/Adequate Enroute Alternate and create a route for RCF procedure. The finished route can be modified interactively directly on the map or manually edited in a field 15 of the FPL. Routes can be freely organized into folders and shared across the company.


Calculations necessary to compile OFP are based on a precise model of the performance characteristics of the particular aircraft.

The calculation of OFP supports ETOPS, SET-OPS, RCF, 3% ERA and planning for an isolated aerodrome.

It is supported by a number of different rules for determining the required fuel (final reserve, contingency, FMC minimum reserve, etc.)

You can easily plan the maximum possible payload and analyze the advantages of transporting fuel.

We adapt the layout of OFP to the requirements of the client and NAVsystem enables multiple templates for viewing OFP.

In the economic module, you can quickly compare the costs of different options, including flight costs for overflight charges.


The OPS board enables the clear view of scheduled flights and their status as a table or a timeline.

The list of displayed flights can be filtered according to specific criteria.

You can easily submit an ATC flight plan and modify it using CHG, DLA, CNL messages.

Allocated Eurocontrol slots are automatically displayed and you can send slot related messages (RFI, SWM, SPA, SRJ,..) directly from the OPS board.

You can also use the OPS board to easily recalculate the flight with changed parameters and the current forecast.

For quick AFTN communication, NAVsystem also includes a gateway for sending any message.


By using the NAVsystem web briefing, you can easily put together your PDF briefing pack, which contains the current OFP, FPL, NOTAM, OPMET messages, maps of upper wind and significant weather.

FIR NOTAMs are selected for the current flight path, which prevents the display of irrelevant information.

To avoid the duplicate listing of information, related flights can be grouped into one PDF.

You can use the briefing to view forecasting levels of wind, temperature, humidity, clouds and visibility.

The web briefing also includes a module for ATC FPL management and mass & balance.


We know from our years of experience working with airlines that every company is unique and has its own specific needs.

Our development team is ready to address these specific needs, whether it is the development of customized modules, reports, imports of data or links to other systems in use.

Integration with other systems considerably speeds up the work and prevents errors in re-entering data, so we are very open to integration with both commercial systems and systems that you have developed for yourselves.


We know that the availability of data in flight planning is key to the operation of every airline. NAV uses SLA to contractually guarantee the availability of software and data.

We make data available and provide services using top server infrastructure, by duplicating data sources and automating the monitoring of services and import of data.

Our data center has 4 separate power sources and 3 diesel generators that provide the continuous supply of electricity.

Connectivity is provided by a fiber-optic network of multiple independent directions and data is regularly backed up in a geographically separate data-center.


Our specialists are there for you 24/7, so you can ask them for support any time.

We offer complete initial training online or on our premises or we will go directly to you to train users.
We also offer refresher training, training on new features and training on selected topics according to your requirements.

Whatever your needs, we are able to provide further training and thus connect theory and practice -> NAVacademy.

„NAVsystem makes life on the flight deck bearable“

The system is easy to understand, nice to use and it is a veritable tool that helps to a great extent on fuel management. The Flight Planning system makes interfacing with Euro Control on long haul flights easy. The Air Traffic Control flight plan can be filed easily, Weather information can be accessed easily, and the Flight Dispatchers confirm that the graphics makes the tool very easy to understand and use. The pilots attest to the fact that it is a good planning tool and makes life on the flight deck in terms of work load bearable.
