This breaking news came out through an accident-related briefing from the Ministry of Land, Infrastructure and Transport.

newst breaking news
I was so angry that I was speechless.
However, although the Ministry of Land, Infrastructure and Transport is the responsible ministry, they are spreading so much incorrect information that we want to provide accurate information.
ruler. Below are some of the detailed airport design guidelines created by the Ministry of Land, Infrastructure and Transport.

Runway end safety area
In determining the length of the runway, sufficient consideration should be given to cover overruns and landings before the runway, which are common occurrences due to adverse operational requirements.
affection
close proximity
On a runway, the localizer of the instrument landing system (ILS) is usually the first obstacle, and the runway end safety area must extend to this facility.
In other situations (non-precision or non-instrument approach runways) the first upright obstacle may be a road, railway or other man-made or natural feature, and in such situations the runway end safety zone should extend to the obstacle.
The runway end safety area is an azimuth facility.
“until”
It needs to be extended.
A few days ago, the Ministry of Land, Infrastructure and Transport withheld its response, saying it was not clear whether the meaning of “up to” was “Up to” or “Including.”
“Up to” means not including the azimuth facility, and “Including” means it includes the azimuth facility.
So, I looked for the original text from which this phrase was taken.
The Ministry of Land, Infrastructure and Transport’s aviation-related laws, guidelines, etc. are all translated from ICAO (International Civil Aviation Organization) annexes and documents.

Now… unfortunately, it is set to up to…
Then, as mentioned earlier, is it correct that azimuth facilities are not included in the runway end safety area?
Of course not.
The Ministry of Land, Infrastructure and Transport did not know English well.
Let’s learn how to use “Up to” in ICAO Doc 9175.
The table below sets the classification standards for runways.
I also brought the classification standards for Korea’s guidelines.

Can you see it?
The Ministry of Land, Infrastructure and Transport has translated “Up to” as “Isang” here.
It is “more than” not “excess.” Of course it is included.
In that case, the “up to” in the phrase below naturally includes the azimuth facility.
On a close runway, the localizer of the instrument landing system (ILS) is usually the first obstacle, and the runway end safety area must extend to this facility.
False briefing from the Ministry of Land, Infrastructure and Transport. I wish it would stop.
