What do you mean by all-weather?

All-weather weather includes all kinds of complicated weather. A general concept. Mainly used in the aviation field. Such as all-weather aircraft, all-weather pilots and so on.

In actual flight activities, all-weather is the general name of visual meteorological conditions and instrument meteorological conditions (originally referred to as simple meteorological conditions and complex meteorological conditions day and night).

There are specific standards for every weather situation. According to the influence of cloud bottom height and visibility, pilots can see landmarks or luminous points clearly. It can be seen that in practice, people often say that all-weather is only part of the weather. All-weather planes that are not affected by any weather have not yet appeared, and further development of science and technology is needed.

Extended data:

All-weather road reflective marking refers to the road marking that can reflect light in dry, wet and underwater to ensure the traffic safety of drivers in bad weather. But it cannot be interpreted as all-weather. It can reflect light all day in rainy and foggy days, but it can't reach the "all-weather" standard in snowy days. So sometimes it is not appropriate to call it all-weather reflective marking;

In this regard, a reflective marking line for rainy nights-reflective beads for rainy nights, that is, crystal beads that can reflect light in dry, wet and underwater, is proposed. When scribing, it can be spread on the scribing surface to achieve the effect of all-weather reflection. Reflective beads for rainy nights are suitable for all kinds of pavement marking coatings, including hot melt, cold plastic, solvent-based, non-slip pavement and two-component marking coatings.
