Di laman Kanta Fresnel:
"Pengangkut pesawat udara dan stesen udara tentera laut biasanya menggunakan kanta Fresnel dalam sistem pendaratan optik mereka. Lampu "bebola daging" membantu juruterbang dalam menjaga lereng luncur yang betul untuk pendaratan. Di tengahnya terdapat lampu kuning dan merah yang terdiri daripada kanta Fresnel. Walaupun lampu sentiasa menyala, sudut kanta dari sudut pandang juruterbang menentukan warna dan kedudukan cahaya yang dapat dilihat. Sekiranya lampu muncul di atas bar mendatar hijau, juruterbang terlalu tinggi. Sekiranya di bawah, juruterbang terlalu rendah, dan jika lampu berwarna merah, juruterbang sangat rendah.[perlu rujukan]
