So if you're flying the 3-degree (most common) glideslope, and you fly it all the way down to touchdown, you'll touch down on or about the Aiming Point. Generally, the Aiming Point is about even with the Glideslope Antenna. I've noticed it says something about "Touchdown zone" but normally we land after the Aiming Point, why is this? Quoting Aeolus ( Reply 4): Thanks everyone! The arrows may be used for take-off, though, unless they're painted yellow, in which case you may only taxi on them.
If there's a displaced threshold with arrows leading to the threshold (piano keys), it simply means that although there is pavement underneath, the aircraft still cannot land before the threshold. Many aircraft land or float beyond the aiming point, few land before it, although the runway is made to be capable. ILS systems are configured to guide aircraft to the aiming point 1000 feet down the runway. (Ignore the dots - airliners wouldn't let me format the spacing correctly without them.)ĭon't know the reasoning if any, but in any case, that's considered the aiming point for aircraft to land - not right at the runway threshold, giving room to spare. and U.K., is the biggest difference that I've noticed as well - forgive my crude example, but
The second set of bars, which are the differences between U.S. They're a purpose of measuring distance for pilots. In all cases, the piano keys are the threshold of the runway (the absolute beginning of the runway capable of handling a landing), then the bars continue every 500 feet for (I believe) 3000 feet. I actually had wondered this too - but I think it's nothing more than differences in the painting patterns.
