Then the last digit (the zero) is dropped, leaving us with 21. For example, a runway that is 214° from the magnetic north would first be rounded to the nearest ten: 210°. Or in a simpler form, the compass bearings of said runway. It is determined by the ‘nearest one-tenth the magnetic azimuth of the centreline of the runway’. The number is slightly more mathematical to work out. The blast pad is usually painted with yellow chevrons and is designed to prevent the ‘blast’ of departing jets from doing any damage to the surface found just before the runway.Ĥ. This is a patch of what looks like the runway, although it is normally not strong enough to hold the weight of a plane, meaning landing on it would cause a ‘catastrophic error’, and cause a lot of damage to both the surface and the plane. The Blast PadĪt the very beginning of most runways, you will find a ‘blast pad’. Airports around the world follow the same guiding principles when it comes to their runway markings, with the aim that by using the same symbols and specific line patterns pilots will be able to safely take off and land the plane at any airport around the world. You can view some of these in Meon’s Case Study for Dublin Airport. There are so many different forms and reasons for different markings within an airport setting, from designated zones for aircraft, taxiways and regulations even for walkways. Effective Line Marking for Every Airport Application
