Bandara sultan iskandar muda (sim) merupakan bandara internasional yang berperan penting dalam mendukung konektivitas dan pertumbuhan ekonomi di provinsi aceh. seiring dengan perkembangan zaman dan dinamika perubahan iklim, evaluasi terhadap orientasi landasan pacu (runway) menjadi penting untuk menjamin keselamatan serta efisiensi operasional penerbangan. runway eksisting 17/35 yang dibangun pada tahun 1943 tersebut sudah digunakan selama puluhan tahun tanpa evaluasi yang signifikan terhadap arah angin dominan. penelitian ini bertujuan untuk mengevaluasi kesesuaian arah runway eksisting di bandara sim terhadap pola angin dominan berdasarkan data historis selama sepuluh tahun (2013–2022). metode yang digunakan mencakup analisis windrose untuk mengidentifikasi arah dan kecepatan angin dominan, serta perhitungan runway coverage untuk menilai kecocokan arah runway terhadap standar (international civil aviation organization) icao. hasil menunjukkan bahwa arah angin dominan berasal dari sektor barat dan timur laut dengan kecepatan 3,6–8,8 m/s. runway eksisting (17/35) hanya memiliki coverage sebesar 91,52%, di bawah standar minimum icao sebesar 95%. alternatif orientasi runway 08/26 menunjukkan coverage sebesar 98,91%. perhitungan kebutuhan panjang landasan untuk pesawat kritis boeing 777-300er menunjukkan panjang ideal sebesar 3.500 meter. temuan ini memberikan rekomendasi perubahan orientasi runway guna meningkatkan keselamatan dan efisiensi operasional, serta menjadi dasar perencanaan infrastruktur bandara ke depan. kata kunci; orientasi runway, runway coverage, crosswind, windrose

Sultan Iskandar Muda (SIM) Airport is an international airport that plays a crucial role in supporting connectivity and economic growth in Aceh Province. With the progression of time and the dynamics of climate change, evaluating the orientation of the runway becomes essential to ensure flight safety and operational efficiency. The existing runway 17/35, constructed in 1943, has been in use for decades without significant reassessment regarding prevailing wind patterns. This study aims to evaluate the suitability of the current runway orientation at SIM Airport in relation to the dominant wind patterns, based on ten years of historical data (2013–2022). The methodology includes windrose analysis to identify dominant wind directions and speeds, as well as runway coverage calculations to assess compliance with ICAO standards. Results show that dominant winds originate from the west and northeast sectors, with speeds ranging from 3.6 to 8.8 m/s. The existing runway (17/35) achieves only 91.52% coverage, falling below the (International Civil Aviation Organization) ICAO minimum threshold of 95%. An alternative runway orientation of 08/26 yields a coverage of 98.91%. The required runway length for the critical aircraft, the Boeing 777-300ER, is calculated to be approximately 3,500 meters. These findings support the recommendation to realign the runway orientation to enhance safety and operational efficiency, and to serve as a foundation for future airport infrastructure planning.
