空服员之飞机窗上面「三角形箭咀」是什么?
话说喺客舱慨某个窗上面有个「三角形箭咀」，以前一直都以为系比工程师用黎整野用，原来系同我地菇都有关系慨。
每边都会有两个慨，前面嗰个系指住机翼慨前缘(Leading edge of Wing) ，面后几行嗰个就会系指住机翼慨后缘(Wing Trailing Edge)。假如前缘慨缝翼(Slats)或者后缘慨襟翼(Flaps)又或者系机翼同引擎出现左问题，机组人员就可以透过呢两个三角形最快搵出最佳慨观察角度同埋位置🔺 🔺 飞机入面都有个神秘过百慕达慨三角🔺

Amazing! I've never thought of it. Sometime the little knowledge seems not useful for a usual day but it may be very important when an accident happens. Thanks for sharing such interesting video.
