See you soon for the opening!
Look at the colour of the panel in the photo and read the caption below.
The sign is green, all is well: the Pilatus is making the rotations!
The yellow sign means that there are 15 knots of wind or more at touchdown and that you need at least a B CoP to jump.
The red sign informs you that the session is suspended due to weather, air traffic or any other reason .
Regardless of the weather, a white sign or no sign means that the centre is temporarily closed.
