For those who read and undertood the lesson, this question should have been clear. The higher up a person is, the longer it takes for the sun to set. Sheikh ’Uthaymīn raḥimahullāh said: “If the Mu'adhin calls the Adhān but you are in a high place and can still see the sun, then you should not break the fast.” [Al-Liqā' Ash-Shahrī (41/22)] Maybe this scenario will make it more clear ⤵️ The Department of Issuing Fatwas and Islamic Affairs in Dubai (*) explained that the residents of Burj Khalīfah, which is 160 storeys high, are required to delay breaking the fast in the month of Ramaḍhān, and those residents who live on floors 80 to 150 are required to break the fast two minutes after the time of the Adhān for Maghrib prayer. For those residents who live on floor 150 and above, the time for the Adhān of Maghrib and ‘Isha’ prayers is three minutes later. For those residents who live on floors lower than the eightieth floor, they may break their fast according to the time of the Adhān for Maghrib in the masjid. __ (*) I don't know how reliable they are, but this is an excellent practical example
