Chapter 7 Airport Charts
Formats of Airport Charts:
• The “classic” chart format
• The “Briefing StripTM” chart format
§7.1 Introduction
The “classic” chart format provides communication information on the right of the chart heading, with airport information on the left.
Heading of “classic” chart format
Heading of “Briefing StripTM” chart format
TMStrip Briefing
This chart format distributes the same information across the top of the chart so that you are reading it from left to right. It’s a widely used format of airport charts.
§7.2 Airport Chart Information
The airport chart contains four primary sections:
• Heading
• Plan view
• Additional runway information
• Takeoff and alternate minimums

§7.2.1 Heading
The top of each airport chart provides standard information about airport, including the location and airport name, elevation, and communication frequencies.
§7.2.1.1 Heading Border
Distinct areas of the heading:
• Location and Airport Name
• Chart Index Number and Dates
• ICAO Location Identifier and Airport Information
• Communications Row

ICAO Location Identifier and Airport Information
The airport identifier, unique to each airport, is a combination of the ICAO regional designation and the airport’s governing agency designation ( IATA).Airport Identifier Airport Elevation

§7.2.2 Plan View
The airport chart plan view portrays an overhead view of the airport, it can provide you with graphical information about the airport, such as its runways and lighting systems.
Except the length and width of stop way and taxiway, lighting system, the other part of charts are portrayed on scale.
§7.2.2.1 Scales, Coordinate Tick Marks and Magnetic Variation
To help you measure distance, the plan view includes a scale showing both feet and meters.
The scale a chart always use range from 1inch=1000feet to 1inch=6000feet.
Scale of the plan view of this chart is 1inch=1000feet

Runway Elevation
The Runway Information is focused on the following items:
• Runway Numbers• Runway Elevations and Length • Displaced Thresholds, Stopways, Overruns• Runway Surface• Arrester Gear and Barriers
• Non-Runway Landing Areas
§7.2.2.2 Runway Information
Runway number is magnetic unless followed by “T” for true in the far north.
Runway number and, when known, magnetic direction unless followed by “T” for true in the far north.
Runway Numbers and Magnetic Direction
Seaplane operating area, or water runway.
Closed runway. Temporarily closed runways will retain their length and runway numbers.
Runway Elevations and Length
Elevations of the runways’ entrance and the lengths of the runways are usually marked at the end and the middle of the runways.
Runway number and Magnetic Direction
Length
of 07R
Entrance elevation
of 07L
Displaced Thresholds and Stop-ways
Displaced thresholds reduce the length of runway available for landings. This portion of runway prior to a displaced threshold is available for takeoffs in either direction, and landings only from the opposite direction.
Stopways or overruns are areas beyond the takeoff runway at least as wide as the runway and centered upon its extended centerline. They may be used to decelerate an airplane during an aborted takeoff.
Runway Surface
In the plan view of the charts, different symbols are used to portray different runway surfaces.
Paved runway
Unpaved runway, such as turf, dirt, or gravel. The type of surface is usually printed on the chart next to the runway.
Seaplane operating area or water runway. Dashed lines indicate the operating area.
Pierced steel planking (PSP)
Area under construction
Unidirectional arrester gear
Bidirectional arrester gear
Jet barrier
Arrester Gear and Barriers
Non-Runway Landing Areas
In addition to runways, the airport chart indicated landing areas as follows:
Helicopter landing pad
Authorized landing area (may be used on Australia charts with limited runway source information
Taxiway and apron
Permanently closed Taxiway

Airport Reference Point
The airport reference point (ARP) is at the approximate geographic center of all usable runway surfaces, and is the point from which official latitude and longitude coordinates are derived. The center of the crosshairs marks the ARP’s exact location. When the ARP is on a runway centerline, an arrow points to its exact location.
Navigational aids
On-airport navaid, such as VOR ,NDB ,or LCTR (locators, other than locators associated with ILS). When navaids are offset from the runway, you may need to make significant adjustments in your final approach course, once the runway is in slight.
RVR measuring site (transimissometer). The primary instrument runways at major airports may have as many as three transimissometers providing RVR readings, which include touchdown RVR, mid-RVR, and rollout RVR.

Wind direction indicators
Cone or wind sock. It is used at both towered and non-towered airports. It can provide the present wind conditions near the runway’s touchdown zone.
Wind tee. Determine the wind direction from a wind tee, but it doesn't indicate wind intensity or gusty conditions. The tail of the tee aligns itself like a weather vane into the wind, so you can take off or land on the runway that most closely parallels the direction of the tee.
Tetrahedron. It is a landing direction indicator, usually located near a wind direction indicator. It may swing around with the small end pointing into the wind, or it may be manually positioned to show landing direction.
§ 7.2.5 Lights and Beacons
The majority of lighting symbols on the airport diagram are approach lights and beacons.

§7.2.3 Additional Runway Information
Some required airport information, such as lighting systems and usable lengths, cannot be portrayed in enough detail in the airport chart plan view.
These information appears below the plan view in the box titled “Additional Runway Information.”
This table provides information for each runway charted in the airport diagram, except for permanently closed runways, ultralight runways, and ski strips.

Note
The first column lists each runway, grouped in approach end pairs. Three types of information are provided for each runway:
• Lighting systems and equipment
• Usable lengths
• Width
§7.2.3.1 Lighting Systems and Equipment
Runway light System includes HIRL 、 CL 、 TDZ. The interval of HIRL is 60m ; interval of CL is

§7.2.3.3 Runway Width
You can also determine the runway width by counting the number of runway threshold stripes, as indicated in the following table:
Runway is grooved; PAPI of 07L is fixed at the left of runway , angle 3°; PAPI of 25R is fixed at the right of runway , angle 3°; HSTIL are located at High-speed taxiways A4 and A6.
§7.2.3.4 Runway Restriction Notes
§7.2.4 Minimums
The bottom part of an airport chart includes up to three separate sections:
• Takeoff minimums
• Obstacle departure procedures
• Alternate minimums
CL operative, centre line of the runway can be seen. One of the TDZ, middle and end of the runaway RVR inoperative, meanwhile the other two operative, the minimum for take off is RVR600FT.
Minimum for adequate Vis Reference
One or Two engines, RVR 50(5000FT) or VIS 1mile; Three or Four engines, RVR 24(2400FT) or VIS 1/2mile.
When take off from 6R, the light 、 visual reference couldn’t meet the standard, the take off minimum require ceiling to be 200ft,meanwhile VIS 1.25SM.
Take off from 6R, keep Minimum climb grads 281FT/MIN until climb to 400FT.
The following is a part of Hong Kong airport which is revised on October 28th,2005. The minimums for the air carriers which adopt JAA and FAR121 take off from Hong Kong are listed in the following chart.
For all airports authorized Category / , if the RVR/VIS is below Ⅱ Ⅲ400m, It is required to establish and apply LVP procedure when taking off .
Takeoff minimums published under the title “AIR CARRIER (JAA)” are based on JAR OPS-1 Subpart E. These minimums are provided for operators not applying takeoff minimums as specified under AIR CARRIER .They are shown in the following table.
The criterion of this table is the category of aircraft, but not according to the number of engines, as FAR dose.
§7.2.4.2 Obstacle Departure §7.2.4.2 Obstacle Departure ProceduresProcedures
§7.2.4.3 Alternate Minimums
When preparing your IFR flight plan, you must consider the weather reports and forecasts for your destination airport at your estimated time of arrival, plus or minus one hour.
If the weather conditions are poorer than those specified by the governing agency, you must list an alternate airport on your flight plan.
To qualify as an alternate, the airport you select, and its forecasted weather for your arrival time, must meet certain conditions.
