All aircraft will be banned from landing or taking off during the English listening comprehension section of the nationwide college entrance exam on Thursday.
The ban will be enforced between 1:05 p.m. and 1:40 p.m. in the vicinity of one-thousand-183 test sites across the country.
Aircraft already in flight will also be advised to remain at least three kilometers above ground during that time in order not to disturb test-takers.
The Education Ministry says some 600-thousand students and college applicants will take the 2017 College Scholastic Ability Test.
