How runways and taxiways are named First up, do you know how to tell the difference between a runway designation and a taxiway designation just by looking at the name?
Taxiway naming conventions Taxiway designations start out with a single alphabet letter, although at larger airports, you may start seeing double-same alphabet letters or alphanumeric identifiers because of the sheer number of taxiways. Where are airport signs located? Destination Signs Destination signs have a yellow background with black text and arrows. Types of Destination Signs There are two types of destination signs: outbound and inbound.
How to Read Destination Signs Outbound destination signs will list the runway number and have an arrow pointing in the direction of travel. Direction Signs Direction signs have a yellow background with black text and black arrows. Types of Direction Signs You will come across two types of direction signs: taxiway direction signs and runway exit signs. How to Read Direction Signs Taxiway direction signs As you approach an intersection, a taxiway direction sign will indicate the designations of the intersecting taxiways and will have arrows pointing in their direction.
Runway exit signs Unlike taxiway direction signs which are always on your left side, runway exit signs are located on the same side of the runway as the exit. Information Signs Information signs have a yellow background with black text. They are used to communicate information like radio frequencies, noise abatement procedures, crossing vehicle roadways and areas not visible from the control tower. Types of Information Signs The colors of an information sign are standardized, but their content can vary by airport.
How to Read Information Signs Information signs are perhaps the last regulated of the six sign types. Location Signs Location signs can have a black background with a yellow border, yellow text, and no arrows. Types of Location Signs Location signs are broken down into 4 types: taxiway location signs, runway location signs, runway boundary signs and ILS critical area boundary signs.
How to Read Location Signs Taxiway location signs Taxiway location signs can be displayed on their own or paired with direction signs or runway holding position signs. Runway location sign Runways have location signs in cases where the close proximity of multiple runways has the potential to cause confusion.
Runway boundary signs At a controlled airport where the tower askes you to report when you are clear of the runway, it is helpful to have a visual indication that you have officially exited and are indeed clear of a runway.
ILS critical area boundary signs Another area that gives you a visual clue as you officially exit it is the ILS critical area. Mandatory Instruction Signs Mandatory instruction signs have a red background with white text. Mandatory instruction signs are used to identify the entrances to critical areas, runways and prohibited areas. As the name indicates, they convey critical instructions, and it is required that you follow them. Types of Mandatory Instruction Signs There are 4 typical types of mandatory instruction signs plus a few other less common ones.
No entry signs are displayed to advise pilots that they are not to enter a given area. How to Read Mandatory Instruction Signs Runway holding position signs When a taxiway intersects with a runway, or a runway intersects with another runway, a runway holding position sign will be posted alongside holding position pavement markings to create a runway threshold.
Runway approach area holding position signs If your taxiway intersects with the approach or departure area of a runway, you will see a runway approach area holding position sign and accompanying pavement markings. Runway Distance Remaining Signs Runway distance remaining signs have a black background with white numerical text. Types of Runway Distance Remaining Signs Usually you will see the standard runway distance remaining signs that list whole numbers, but on short, unpaved runways, you may instead see one-half distance remaining signs.
How to Read Runway Distance Remaining Signs Runway distance remaining signs can be located on one or both sides of the runway.
Combination Signs We already mentioned that some types of signs may be displayed in combination with other types of signs. Reading the Airport Diagram Now that you have developed a baseline familiarity with the types of signs you are likely to see while flying, the next step is to put them all together and understand how you use them in real life flight scenarios.

Have you ever considered how it is runways are arranged or what the different markings, signs and layouts mean?
There are different airport runway markings used to provide pilots with directions and to assist them operationally. Markings for runways are white, while taxiway markings, areas not intended for aircraft use and holding positions are yellow.
While airport runway markings are painted on the surface of a runway, signs can either be vertical or painted on the surface as well. What is the significance of each? Runways are numbered based on their compass bearings, measured in tenths of a degree. Imagining a compass, represents north, 90 represents east, , south and denotes west.
Runways are numbered between 01 and 36, and to identify a runway, the zero is dropped from the magnetic heading the runway is facing. For instance, a west-facing runway with a heading of degrees translates to runway 27 and so on. A runway going East to West works in both directions depending on which way the wind is blowing.
It is therefore 2 runways, 9 and All runways are numbered using 2 numbers, 18 apart because of degree difference. If there are four or more runways, an airport will change the numbers for differentiation. The Deer Valley Airport provides parallel runways. This allows opportunity for double the amount of aircraft and operations, since both runways can be in use at the same time. However, the runways are rotated by a couple of degrees in comparison to Deer Valley.
The French Valley Airport offers a single airport runway, as there is a low amount of traffic in the area. The small traffic number allows for students to focus and hone their skill with less distraction. Like on the city streets, those red signs indicate an intersection between runways or taxiways, according to The Points Guy. That means pilots need to stop their planes and wait until they get the all-clear from airport ground control to cross to make sure they aren't getting in the way of an airplane trying to take-off.
A red sign with the numbers means that Runway 11 is on the left, while Runway 32 is on the right. If you spot a black sign with white letters, they indicate the distance remaining for take-off and landing. They run along the sides of runways at foot increments and could show passengers how long it will be until take-off. A welcome sign to anyone stuck on a plane during a delay.
By Melissa Locker. There are no passing lanes on a runway! Centerline stripes are standardized to be precisely feet between the start of one stripe and the beginning of another. If a runway is over 4, feet long, it gets an aim point markings. These are two large white blocks located 1, feet from the threshold. The give the pilot a rough idea of where they should touch down. Aim point markings are feet long. According to the Aeronautical Information Manual , runways are divided into three different categories based on the instrument approach leading pilots to the runway.
The runway described above is a basic visual runway that has no instrument approaches. An instrument approach allows pilots to descend to the airport from altitude while visibility is low.
It makes sense that if a pilot is on an approach and looking for a runway, then the runway markings should be bold enough to help the pilot spot it. Non-precision approaches usually allow pilots to descend within feet of the surface with about one mile of visibility. Non-precision runways always have the four features mentioned above for increased visibility. Precision approaches allow pilots to descend even lower in lower visibility.
The minimums vary depending on the exact type of approach, but a regular ILS approach will allow pilots to get within feet of the runway in a quarter to a half-mile of visibility. As a result, the runway is marked with everything mentioned above, plus sidelines on the edges and a distinctive touchdown zone marking.
The touchdown zone markings are sets of white bars on each side of the runway, each feet from the next. The threshold markings are enhanced and include a series of parallel white bars across the runway threshold, the number of bars depending on the width of the runway. All of this makes the runway more visible. Another possible area where the runway markings can help is during low visibility takeoffs.
Pilots should have adequate visual references when taking off in bad weather , and the better the runway markings, the better their visual references are. Signs are standardized around airports , so the meaning of them should be apparent to pilots even as they pass quickly on a runway. The most important sign on an airport indicates that a pilot is about to cross a runway.
Runway intersections, whether two runways meet or a taxiway crosses a runway, are marked by red signs with white letters. They include the runway designator numbers.
For example, this sign would indicate that the pilot is about to cross Runway From the direction they are approaching, Runway 4 is to the left, and Runway 22 is on the right they are the same piece of asphalt, but used in different directions.
