Abstract

Halk tarafından genelde kara kutu olarak bilinen
FDR(Flight Data Recorder) ve CVR(Cockpit Voice Recorder) kayıt cihazları
havacılık için çok önemlidir. Havacılıkta FDR ve CVR cihazlarına takılı olarak
kullanılan ULB(Underwater Locator Beacon) ise su ile temas ettiğinde belirli
bir frekansta akustik sinyal yayan bir sualtı ses vericisidir. Enkazın suya
battığı hava aracı kazalarında, arama – kurtarma ekiplerinde bulunan akustik
alıcılar vasıtası ile ULB sinyalleri tespit edilir ve kayıt cihazlarının
sualtındaki konumları hesaplanır. Bu sayede kayıt cihazlarına ve uçak enkazına
ulaşılabilir, kazanın kök nedenlerini bulmak için araştırmalar yapılabilir. Son
yıllarda yaşanan bazı uçak kazalarında okyanusa düşen uçakların arama
çalışmalarında ULB cihazlarının tespit edilemediği görülmüştür. Havacılık
dünyasında sık tartışılan bir konu haline gelen ULB regülasyonları ile ilgili
otoriteler bazı değişiklikler yapmışlardır. Bu çalışmada, sualtı akustik
doğasının karakteristik özelliklerinden kaynaklanan etkilerin dışında, ULB
cihazlarından beklenen performansın alınamamasının olası nedenleri, otoriteler
tarafından yapılan değişikliklerin muhtemel etkileri ve hali hazırda problemin
devam etmesine neden olabilecek faktörler incelenmiştir.

Abstract

FDR (Flight Data Recorder) and CVR (Cockpit
Voice Recorder) devices, which are known as black boxes by the public, are very
important for aviation. ULB(Underwater Locator Beacon) is an underwater sound
projector which is activated by water immersion and it is attached to FDR and
CVR in aviation use. If an aircraft is submerged in water after an air
accident, ULB signal can be detected by hydrophones held by SAR teams and then
underwater locations of the recorder devices will be calculated. Thus, wreckage
and recorders can be found and investigations can be carried out to find out
root causes of the accident. ULB devices could not be detected during search
operations of some accidents occurred over the ocean in recent years.
Authorities have been making some changes to ULB regulations which become a
matter of debate in aviation community very often. In this study, possible
causes of the unexpected low performance of ULB devices besides the effects
originated by natural characteristics of the underwater acoustic environment,
potential improvements of changes made by authorities, and existing other
factors which may contribute to the problem were examined.
