It is hazy all day. The lighthouse disappears in the fog and you can not see the horizon.
Everything is covered with fine grown ice crystals. There is a jingling noise when running in it.
The 10m mast is put up and the instruments are connected and tested. The anchoring is done by wooden sticks that quickly freeze in drilled holes.
We fly some low circles with the SUMOs in the late afternoon. The moisture immediately settles as ice on the propeller and the leading edge of the wing.
The performance of the aircraft decreases slightly with the changed surface of the wings and the propeller. We land before it is critical. How nice that there is de-icing for man-carrying planes.
