飞行圈今天在讨论机场瞄准点和接地带的的标志问题：
有机长咨询，怎么查找我国哪些机场是FAA的样式，哪些是ICAO的样式？
这个问题应该是来自波音的FCTM：
对于飞行员来说，因为按照图示说明，飞行员习惯的瞄准大白点落地时有些微的差别，美国的大白点是在距离跑道入口300米的地方，而ICAO的标准是距离跑道入口400米的地方。
FAA的标准
那么具体到FAA的精密进近的跑道的距离标志是怎么规定的呢？
RUNWAY TOUCHDOWN ZONE MARKINGS AND FIXED DISTANCE MARKINGS
Distance from approach end of runway to beginning of the markings
500' Touchdown Zone. Three bars 75' long on each side of the centerline. They are the beginning of the fixed distancemarkers. Fixed distance markers are postioned 500' apart.
1000' Thousand Foot Fixed Distance Marker. One “heavy” bar
on each side of the centerline, 150' long and 30' wide.
1500' Two bars, 75' long, on each side of the centerline.
2000' Two bars, 75' long, on each side of the centerline.
2500' One bar, 75' long, on each side of the centerline.
3000' One bar, 75' long, on each side of the centerline.
ICAO的标准是这样的：
RUNWAY AIMING POINT MARKINGS
APPLICATION
An aiming point marking will be provided at each approach end of a paved instrument or noninstrument runway.
LOCATION AND CHARACTERISTICS
An aiming point marking consists of two conspicuous stripes in conformity with the dimensions shown for the runway patterns in the example shown under “Runway Touchdown Zone and Aiming Point Markings“.
说重点，那么我国的标准是什么呢？
依照中华人民共和国民用航空行业标准 MH5001-2013《民用机场飞行区技术标准》
