The idea of canting or skewing the landing area to port of the ship's centreline had evolved from experiments with a rubber deck and Sea Vampire fighters without undercarriages in HMS Warrior in 1948. Although the rubber deck itself proved impractical, the 'skewed deck' as it was called at first was seen as a very effective way of making arrested landings safer on existing, relatively small, flight decks.

楼主的看法是斜角甲板就是为了喷气机能够安全降落设计的，试想如果戴高乐号甚至未经改装的埃塞克斯级航母都是直通甲板，只要她们愿意在载机降落时把甲板清空，现在的舰载机都能安全降落，即便没有挂上拦阻索，也和斜角甲板一样能够复飞。
