What is a Type II Blind Landing System? What are the requirements for airports and pilots?

The second type of blind landing system is that the visibility is less than 400 meters, the visual range of the runway is not less than 350 meters, and the landing standard is not less than 30 meters. The requirements for airports and pilots are to test the pilot's eyesight, the pilot's judgment ability, the pilot's mastery and control ability, and the pilot's ability to control the aircraft, so at this time, the pilot's ability is more tested.

It is that when you are busy, the requirements for the navigation settings and operating system are relatively high. The requirements for the airport are that the runway should have a visual range of 350 meters, a visibility of 350+ clouds, a height of 30 meters, a decision height of 30 meters, a radio, a lighting equipment, and chemical smoke. The requirements for pilots are to undergo special training, have sufficient experience, and have a strong psychological quality and self-judgment ability.

The second-class blind landing system thinks that if an unexpected situation is encountered, it can be landed by emergency landing. The requirements for the airport and the pilot are very strict, and then the pilot needs to be able to deal with it calmly, and in this case, it is necessary to contact the airport staff to confirm that there is no danger before landing.

Visibility 400 meters, cloud ratio height 30 meters, decision height 30 meters; The condition for the airport is to have low beams, runway signs and other equipment, and pilots are required to have relevant qualifications and be inspected every year.

Blind landing: Under the condition that the visibility in front is not less than 800m or the runway visual range is not less than 550m, with a high probability of success in approaching, the aircraft can be guided to a decisive altitude of 60m (above the middle finger mark).

The bending effect of blind descent is particularly prominent in the case of bad weather and low visibility. It can provide a reliable approach and landing route for the aircraft when the runway or signs are difficult for the pilot to see with the naked eye, so that the pilot can grasp the position, bearing, and descent altitude to land safely. According to the precision of blind landing, blind landing provides different approach and landing standards for aircraft, so blind landing can be divided into and class standards.

Blind landing is the common name for the Instrument Landing System (ILS), and the standard for blind landing is a front visibility of 400 meters (1 4 miles) or a runway visual range of not less than 350 meters, and the minimum landing standard decision height is not less than 30 meters (100 feet). The autopilot descends to a decision altitude of 30 meters, and if the pilot sees the runway, he can land, otherwise he has to go back to flight.

The second-class blind landing system refers to the system that guides the aircraft and the airport to land under the conditions of the second-class blind landing.
