最近,阿拉斯加机场安装了辐射发光灯——氚灯。这种灯可在无电源的情况下,连续照明十年之久。阿拉斯加冬季光照时间短,飞机飞行大多数是在黑暗中进行。每当驾驶员要在简易机场降落时,飞机先在机场上空发出嗡呜声,然后盘旋,等待村民把足够的汽车开到跑道附近,用车头灯照射跑道为飞机指路。但因亮度不够,经常发生事故,该州的飞行事故率是全国平均数的两倍。
Recently, the Alaska airport installed a radiant light - a neon lamp. This lamp can be continuously illuminated for 10 years without power. Alaska has a short winter illumination time, and most aircraft flights are conducted in the dark. Whenever the pilot is about to land at the airstrip, the aircraft makes a buzzing noise in the air above the airport, and then hovering, waiting for the villagers to drive enough cars near the runway and use the headlights to illuminate the runway to guide the aircraft. However, due to the lack of brightness, accidents often occurred and the flight accident rate in the state was twice the national average.
