Mengapa Penumpang Keluar Masuk Pesawat dari Sisi Kiri? Ada beberapa hal tentang pesawat terbang dan perjalanan yang kadang dianggap remeh. Salah satunya, mengapa penumpang selalu naik pesawat dari sisi sebelah kiri? Jika Anda beranggapan pola tersebut hanya terjadi di maskapai Indonesia, tentu saja tidak. Semua maskapai penerbangan dunia menggunakan sisi sebelah kiri untuk menaikkan dan menurunkan penumpang. Aturan tersebut ternyata bukan tanpa alasan. Ada dua alasan besar yang membuat keputusan tersebut diterapkan di semua maskapai penerbangan komersil. "Dulu bandara disiapkan agar pesawat bisa menerima taxi (proses jalan di darat menuju runway) di depan terminal dan berhenti untuk mengeluarkan penumpang. Ini berguna bagi pilot untuk bisa mempertimbangkan jarak ruang sayap dari gedung terminal dan memasang pintu pesawat di depan pintu terminal," kata mantan pilot Angkatan Udara Amerika Serikat di Quora. Selain itu, menempatkan jalan keluar masuk penumpang di sisi kiri sebab awak yang berada di sisi kanan merupakan petugas yang mengendalikan pesawat. Di samping itu, kondisi tersebut merujuk pada pesawat yang memiliki port di sisi kiri dan starboard atau steerboard di sisi kanan, dilansir dariTravel and Leisure.
