One of the most challenging issues in recent years is the emission gases released into the atmosphere by aircraft. In this study, emissions gases (HC, CO, and NOx) originating from B737-800 and A320 aircraft, which are among the most frequently used aircraft types in the LTO (Landing and Take-Off) process at Dalaman Airport (IATA: DLM - ICAO: LTBS) and Milas-Bodrum Airport (IATA: DLM, ICAO: LTFE) between 2015 and 2021 have been calculated. Muğla, being a primary tourism destination with approximately a six-month tourism season, Dalaman and Milas-Bodrum airports are among the busiest airports in Turkey. The fuel ratios and emission factors used in the calculations were obtained from ICAO and the Engine Data Bank. Flight data was obtained from DHMI. Emission gases released were calculated using the Tier 2 method. NOx emissions are most visible during take-off and climb phases, while CO and HC emissions are most prominent during the Taxi phase. This is because the engine thrust power is higher during take-off and climb phases than in other phases. In the Taxi phase, engine thrust power is at its lowest level, which is why CO and HC emissions are more prominent.

2015-2021 YILLARI ARASINDA MUĞLA İLİNDE LTO DÖNGÜSÜ ESNASINDA B737-800 VE A320 TİP UÇAKLARDAN KAYNAKLANAN EMİSYONUN GERÇEK ZAMANLI HESAPLANMASI

Son yıllarda en çok mücadele edilen konulardan biri uçaklar tarafından atmosfere salınan emisyon gazlarıdır. Bu çalışmada 2015-2021 yılları arasında Dalaman havalimanı (IATA: DLM- ICAO: LTBS) ve Milas-Bodrum havalimanındaki (IATA: DLM, ICAO: LTFE) LTO sürecinde en sık kullanılan uçak tiplerinden olan B737-800 VE A320 uçaklarından kaynaklanan emisyon gazları (HC, CO ve NOx) hesaplamıştır. Muğla, yılda yaklaşık 6 aylık bir turizm sezonu ile ana turizm destinasyonu olduğundan, Dalaman ve Milas-Bodrum havalimanları tüm Türkiye'nin en yoğun havalimanları arasındadır. Hesaplamada kullanılan yakıt oranları, emisyon faktörleri ICAO ve Motor Veri Bankasından alınmıştır. Uçuş verileri DHMİ’nden alınan verilerdir. Yapılan çalışmada salınan emisyon gazları Tier 2 metoduyla hesaplanmıştır. NOx emisyonu en çok kalkış ve Tırmanış fazında görünürken, CO ve HC emisyonları en çok Taksi fazında görülmüştür. Bunun nedeni ise kalkış ve tırmanış fazlarında motor itki gücünün diğer fazlardan fazla olmasıdır. Taksi fazında ise motor itki gücü en düşük seviyededir bu sebeple CO ve HC emisyonları fazladır.
