Penelitian ini bertujuan untuk mengetahui arah angin Headwind, Tailwind, dan Crosswind yang berpengaruh terhadap penurunan performa pesawat dan gangguan keselamatan penerbangan saat take off dan landing. penelitian ini hanya memfokuskan ke angin berbahaya atau angin crosswind. Penelitian ini diambil di bandara Adisutjipto Yogyakarta di bagian kantor Meteorologi Angkatan Udara. Dari hasil data yang diperoleh peneliti menggunakan program microsoft exel untuk pengolahan data. Sehingga dapat mengetahui besar maksimal crosswind dan besar maksimal rata-rata crosswind yang di peroleh selama perbulan yang di terima oleh pesawat saat take off dan landing baik dari sisi kanan maupun kiri pesawat. Hasil penelitian menunjukan bahwa pada rentang waktu 23.00-03.00 UTC besar maksimal rata-rata crosswind sebesar pada Januari 2015 sebesar 2,9 knot. Rentang waktu 04.00-08.00 UTC dengan besar maksimal rata-rata crosswind pada bulan Januari 2015 sebesar 7 knot. Waktu 09.00-13.00 UTC dengan besar maksimal rata-rata crosswind pada bulan Agustus 2015 sebesar 5,5 knot dan waktu 14.00-17.00 UTC dengan besar maksimal rata-rata crosswind bulan April 2015 sebesar 1,6 knot knot.

Airlines are also starting to use wide body aircraft such as the Airbus A330-900 Neo. For regular flights, the average plane used is a narrow body, while for Hajj and Umrah it is a wide body. Therefore the airport needs to prepare the capacity and area of the apron area to serve wide body aircraft such as the A330-900 Neo which are currently used by Lion Air and Garuda Indonesia airlines. The research method used in this study is Simple Linear Regression, whereby this method is obtained for the calculation results of forcasting the number of aircraft movements in 2023 at Adi Soemarmo International Airport, Boyolali for arrivals is 17,636 aircraft movements and departures are 17,627 aircraft movements, so the total of the total movement of these aircraft is 34,903 aircraft. The results of data analysis and processing of the number of parking stands in the apron area of Adi Soemarmo Boyolali International Airport in 2023 during peak hours are 12 parking stands for narrow body aircraft and 3 parking stands for wide body aircraft. So that the minimum area required for the apron of Adi Soemarmo Boyolali International Airport in 2023 to accommodate Narrow Body and Wide Body aircraft is 100,788.355 m 2 .
