The VSKYLABS Aeroprakt A22-LS Project was updated earlier this week to v1.07. The update included interaction addition, which is a built-in binding capability of the braking lever to a Joystick axis. Quite useful for those who are focusing on Joystick hardware controls and would want to fly the aircraft with the *real* feel.

Braking in the A22 is made by a single lever which activates both brakes symmetrically (similar to the braking system in the Flight Design CTLS aircraft). Now, with the use of the built-in axis assignment, it can be done not only in VR/on-screen/switch/button... but also with the use of a dedicated Joystick axis.

More information regarding this update can be found in the project's main pages (update log / POH), also in the VSKYLABS support forums.

The VSKYLABS A22 is expecting a major upcoming update, which will include the addition of a new variant: A Floats equipped Foxbat! Update will take place in the near future.

The VSKYLABS ICON-A5 Project was updated as well. This time it was a minor update: added payload weight interaction with the passenger, also the passenger model was refined for better visualization. More information can be found in the project's main pages (update log / POH), and in the VSKYLABS support forums.

For quite some time, VSKYLABS is researching/experimenting/developing advanced Hot Air Balloon simulation for X-Plane by laminar research flight simulation environment.

Development has reached advanced 'Proof Of Concept' stage, where all core elements of Hot Air Ballooning are being constructed and tested altogether, to include: Burners and hot-air simulation (inside the envelope), Pressure scoops (skirts), operational Parachute valve and valve lines, Envelope aerodynamics and physics and more.

In short, temperature difference between the air inside the envelope and the ambient air surrounding it will determine the lift of the Hot Air Balloon. So the pilot uses the burner/s to heat up the air inside the envelope and the result is "lift". When the air cools-down inside the envelope, lifting force is decreased and the Hot Air Balloon will gradually begin to sink. For more precise control over the cooling of the envelope, a Parachute Valve is located on top of the envelope, and the pilot can pull a line that opens the valve, allowing hot air to get outside through the upper portion of the envelope, to allow a more rapid cooling of the air inside the envelope. Therefore, the pilot has the burner to heat the envelope, and the parachute valve to cool it down. By managing these, he can climb or descent to the desired altitude. Without fuel, the air inside the envelope will gradually cool down, and the Balloon will not be able to stay up in the air...so fuel management is crucial.

The Hot Air Balloon pilot must prepare his flight with a lot of considerations. Specific weather conditions are required to allow a safe flight. High-level meteorologic knowledge is required, as well as accurate, real-time meteorological data.

Hot Air Balloons utilize wind and its direction to be carried on in the atmosphere (to be drifted). Wind direction and speed changes with altitude, and navigating a Hot Air Balloon throughout the required altitude layers is very challenging. The pilot must pick the right altitude that offers the best wind direction and speed for the planned flight.

Development/evaluation of the projects covers full-scale 4-5 people Hot Air Balloon simulation down to single-seat 'Hopper', and Powered 'Hopper' simulation. These are single seat Hot Air Balloons without any basket, and the pilot is hung underneath the Balloon.

The 'Hopper' and the Powered 'Hopper' are taking the lead in development and testing, and the experience here in the 'Labs, so far, is no less than STRIKING. Navigating and landing a Hot Air Balloon in X-Plane sets a high level of airmanship and it is very rewarding. This 'striking' experience lead to the decision to proceed and develop full-scale Hot Air Balloon projects with ultimate VR experience, ***and with high level of educational/scientific value***.

Stay tuned for more News on this fascinating project/s!

OK now it is official. The VSKYLABS 'Test-Pilot': Hopper Project for X-Plane by laminar research (work in progress) is listed now in the VSKYLABS 2021 releases road-map. The project introduces a highly realistic hot air balloon simulation in the form of a powered 'Hopper' vehicle (a single seat hot air balloon). All hot air balloon physics, systems and elements are being simulated.

Here are a few screen shots showing the evolving 'Production' prototype. Stay tuned for the *PERFECT* upcoming X-Plane educational / scientific project!
