Aeronautical Navigation Systems



ESNAH is a young dynamic Belgian company active in air navigation safety for general aviation. Our vision is the creation of a new generation of navigation tools for student pilots, private and commercial pilots, schools, aero-clubs, aircraft owners and operators.


It was during his private pilot training (PPL) that Nicolas Hanse realised that the necessary information for flight preparation are abundant but are not easy to obtain reliably and organise. This is how the idea of a complete system designed to assist pilots with the preparation of their navigation and flight was initiated. This future software was born and called SkyLiberty, the freedom to discover the sky in security.

Flight Plan

In the first step of the project, Nicolas professionalised his approach with the help of Challenge, Innovatech and ASE. After a market and competition study, the business plan and bill of specifications, the project was given a high potential for success. From this point forward, the project was defined. In the mean time, Nicolas started an air transporter pilot training (ATPL).

Start Engine

After more than two years of conceptualisation, Aurélie Simon joined the project. Together with Nicolas Hanse they created ESNAH. The begin of the great adventure had started.
In July 2012, the company obtained the European Spatial Agency support. ESNAH is the first walloon company incubated by ESA Bic Redu (ESA Business incubation center - Since then, ESNAH has also gain support of WSL and Réseau Entreprendre Wallonie.
After gathering the necessary financing, thanks to several partners, all signals were on green to go on with project development.
Ou : Thanks to our partners, necessary finances allowed to carry on with project development.


In September 2013, SkyLiberty began to take shape thanks to the arrival of 2 developers (Android and iOS) in the ESNAH Crew.

Take Off

January 2015, a historical month in the existence of the young ESNAH. Take off is imminent! It is now official, the first version of SkyLiberty is available!

In flight

The start of SkyLiberty sales is in fact the beginning. Indeed, ESNAH Crew is constantly looking for new functionalities with the hope that it will meet your expectations.



The strength of the SkyLiberty is neither only the technology used nor the sophistication of the concept but the team who developed the solution. In ESNAH we work as a crew and each one assume his responsibilities. The aeronautical know-how, the worried of details and the ambitious are a requirement for everyone works in ESNAH. Nothing is du to chance !

ESNAH is animated by values towards his clients, his crew and also the environment.

To all the pilots of general aviation:

Provide reliable tools and data compiled in only one application with an intuitive, ergonomic and secure interface aiming to increase air security

To co-workers:

The corporate culture of ESNAH is based on team spirit, respect, responsibility, surpassing oneself and continuous training.

To the environment:

ESNAH has a sustainable development approach, as well within it’s activities (solar cells, recycling, limitation of natural resources,..) as within SkyLiberty itself, a paperless application. Moreover, ESNAH support the Jane Goodall Institute Belgium association, named after the English primatologist, which promotes respect for all living being (animals, persons and environment) around the world.

To fly free, safely, whilst enjoying beautiful landscapes, that is every pilot’s dream.
Unfortunately, last decades, the state of environment is considerably degrading at a worldwide scale : deforestation, pollution, global warming,..
Wishing to participate actively in environmental protection, ESNAH is associated with Jane Goodall Institute Belgium to act in favour of sustainable development and biodiversity.
One of the Jane Goodall Institute’s activity is trees plantation over the world.
For each SkyLiberty’s module bought, 0,50 € will be deposited to this association via JGI Belgium.
For information, a tree plantation cost 7 €. Your contribution is visible in the store of your SkyLiberty.

If you want to bring an additional contribution to environment protection, don’t hesitate to make a donation.

SkyLiberty is a mobile application and a web-application that allows the pilots to manage all sides of their pilot life. It is also the bridge between them and the data you manage in the SkyOperator application. They can, for example, compute an accurate Mass & Balance with verified information you fill in the POH, submit bookings, flight logs, eventual defect reports and real-time information directly from the app.

SkyOperator is an application working on any web-browser. It is the application you will use to manage your fleet and your pilots. There, you can fill a complete digital POH for each of your aircraft that will be shared with your pilots. You can also handle the flight logs, the defect reports, and the realtime data your pilots submitted or the booking they made. And since all the communication between you and your pilots, despite all our efforts to simplify them, can’t be reduced to boxes to check, we added a classic messaging.
