When can you cross the hold short line?
When can you cross the hold short line? When approaching the holding position marking, pilots must not cross the marking without ATC clearance. The ILS critical area is not clear until all parts of the aircraft have crossed the applicable holding position marking.
What is the difference between holding point and hold short?
Holding short is very important. It means stopping before entering a runway area and is marked by two solid lines. You should hold short (ie, before) the solid lines. The holding position however, is a place on the ground where aircraft are to report once they taxi to it.
Why are runways always 27?
Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.
