Influence of low visibility on pilots

The direct impact of smog on military flight is the reduction of visibility. Low visibility leads to blurred vision of pilots, which can't effectively distinguish ground obstacles, navigation lights, etc., thus causing potential risks such as aircraft deviating from or rushing off the runway, which may lead to serious safety accidents or hidden dangers.

The decrease of visibility first affects the normal take-off and landing of military aircraft, especially in the landing stage. Of course, different planes and airports will be affected by different degrees of low visibility because of different landing guidance systems, different pilot training levels and different aircraft take-off and landing flight performance. Early military aircraft had to meet considerable visibility to land safely.

Extended data For aviation safety, visibility is one of the important criteria to determine the take-off and landing of aircraft, and it is also a necessary factor to ensure the safe take-off and landing of aircraft.

Of course, there are many weather phenomena that affect aviation visibility, such as thunderstorm, thunderstorm, rainstorm, freezing rain, wind shear, too much downwind, icing, heavy snow, low clouds, low visibility, fog and so on. Among them, fog has the greatest influence on visibility, and the haze weather formed today is even more fatal to the take-off and landing of aircraft.

When determining the take-off and landing capability of an aircraft, an indicator that often appears together with visibility also includes the height of the cloud bottom. Even in the case of good visibility, if the height of the cloud bottom is low, the pilot can only see the runway after crossing the clouds and descending. Without an advanced landing guidance system, pilots may not be able to respond in time.

People's Daily Online-Daxing Airport will conduct a low visibility verification flight next week.
