What are the steps to be taken during heavy snowfall on pressostatic balloons to eliminate snow accumulation on the top of the canopy and thus avoid problems?

In case of snow, it is advisable to maintain an overpressure of at least 20 mm water column (unit of air pressure) inside the balloon. This can be done by closing the air calibration lever, located on the recirculation of the generator. If this is not sufficient, it will be necessary to manually activate the emergency unit. Two other useful tips are to turn on the heating system and set it at a constant temperature of at least 17 C° and to turn off all hot air destratification systems (destratifier fan) if present, to allow the hot air to rise and stratify over the top of the canopy, thus facilitating the melting of the snow present on the top of the balloon and preventing its accumulation.
