Gece, bulut veya sis i\u00e7i u\u00e7u\u015flar\u0131, havac\u0131l\u0131k vertigosu i\u00e7in daima bir risk olmu\u015ftur. Pilotun havadaki pozisyon alg\u0131s\u0131n\u0131 (spatial orientation) bozan risk unsurlar\u0131ndan bir ba\u015fkas\u0131 da gece g\u00f6r\u00fc\u015f g\u00f6zl\u00fckleridir (GGG). Bu g\u00f6zl\u00fckler, gece u\u00e7u\u015flar\u0131nda inan\u0131lmaz avantajlar sa\u011flamakla birlikte, normalde 130 derece olan g\u00f6r\u00fc\u015f a\u00e7\u0131s\u0131n\u0131 40 dereceye d\u00fc\u015f\u00fcr\u00fcr; yani bak\u0131lan yer daha dar bir a\u00e7\u0131dan g\u00f6r\u00fcl\u00fcr. Ayr\u0131ca renk sadece ye\u015filin tonlar\u0131ndan ibarettir; derinlik ve mesafe alg\u0131s\u0131 da, g\u00f6r\u00fc\u015f keskinli\u011fi de g\u00f6rece azd\u0131r. GGG kullanarak bu k\u0131s\u0131tl\u0131l\u0131klara giren bir pilot, ilaveten bir de sis ve gece karanl\u0131\u011f\u0131n\u0131n g\u00f6r\u00fc\u015f zorluklar\u0131yla kar\u015f\u0131la\u015ft\u0131\u011f\u0131nda, havadaki pozisyonunu yanl\u0131\u015f alg\u0131lamaya ba\u015flayabilir; yer-g\u00f6k, a\u015fa\u011f\u0131-yukar\u0131 alg\u0131lar\u0131 bozulabilir. Durumu d\u00fczeltmek amac\u0131yla verdi\u011fi sert kumandalar, hava arac\u0131nda ivmeli hareketlere, bu da i\u00e7kulak denge organ\u0131nda (vestib\u00fcl) pozisyonel ill\u00fczyonlara neden olabilir. Bu durumda ilke, alet u\u00e7u\u015funa ge\u00e7mek, bozulmu\u015f alg\u0131lara g\u00f6re de\u011fil, aletlerin g\u00f6sterdi\u011fine g\u00f6re u\u00e7u\u015fu s\u00fcrd\u00fcrmektir. Ama bazen bu his yan\u0131lg\u0131lar\u0131 o kadar bask\u0131n olabilir ki, pilotu yanl\u0131\u015f kumandalar vermeye zorlayabilir. Askeri havac\u0131l\u0131kta vertigo nedeniyle olan kazalar\u0131n oran\u0131 %15 kadard\u0131r ve bunlar\u0131n %90’\u0131 da \u00f6l\u00fcmc\u00fcld\u00fcr. TSK’da bu riski azaltmak amac\u0131yla vertigo e\u011fitim cihazlar\u0131 kullan\u0131lmaktad\u0131r. Bu titiz \u00e7al\u0131\u015fmalara ra\u011fmen bu elim kaza olmu\u015ftur ve “neden olmu\u015ftur?”un cevab\u0131n\u0131 aramak zorunday\u0131z.
