A World Aeronautical Chart (WAC) was a type of aeronautical chart used for navigation by pilots of moderate speed aircraft and aircraft at high altitudes in the United States. They are at a scale of 1:1,000,000 (about 1 inch = 13.7 nautical miles or 16 statute miles). WACs were discontinued by the Federal Aviation Administration (FAA) in 2015.
These charts are similar to sectional charts, and the symbols are the same. However, there is less detail at the smaller scale, so it is seldom used for visual flight rules flight at slower speeds or for local flights. WACs show topographic information, airports and radio navigational aids. They are useful for strategic flight planning, where a view of the entire flight area is useful.
These charts are revised annually, except for several Alaskan charts and the Mexican/Caribbean charts which are revised every 2 years. Australian WAC charts are amended every 3 to 5 years.
A set of 12 WACs covered the continental United States and 8 others covered Alaska. Canadian airspace is covered by a set of 18 WACs. The 43 Australian WACs are indexed according to a geographic name or a corresponding 4-digit number.
Unlike sectional charts, North American WACs are named according to an international "grid system" having a combination of letters and numbers. For example, WAC CF-16 covered the Pacific Northwest, and E-15 covers the British Columbia area. Letters progress from A at the north pole to U at the southern tip of Argentina. The numbers generally progress from 1 at the Greenwich meridian and increasing to the east, to a maximum of 29, depending upon the number of charts required at that latitude.
On June 23, 2015, FAA officially stopped providing the World Aeronautical Chart due to a decline in interest and technological advances. Charts: CC–8, CC–9; CD–10, CD–11, CD–12; CE–12, CE–13, CE–15; CF–16, CF–17, CF–18, CF–19; CG–18, CG–19, CG–20, CG–21; CH–22, CH–23, and CH–24 ceased to be printed beyond September 17, 2015. Charts: CH–25; CJ–26, and CJ–27 production ended upon their next scheduled printing dates of December 10, 2015; February 04, 2016, and March 31, 2016 respectively. [1]
Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as outer space which is the expanse or space outside the Earth and aerospace which is the general term for Earth's atmosphere and the outer space within the planet's vicinity. History:
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways:
A NOTAM is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are notices or advisories that contain information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which may be essential to personnel and systems concerned with flight operations.
In United States and Canadian aviation, the Aeronautical Information Manual (AIM) is the respective nation's official guide to basic flight information and air traffic control procedures.
Alliance Municipal Airport is in Box Butte County, Nebraska, three miles southeast of the city of Alliance, which owns it. Denver Air Connection offers scheduled passenger flights to Denver, which are subsidized by the Essential Air Service program.
The Airport/Facility Directory, now identified as Chart Supplement in the U.S., is a pilot's manual that provides comprehensive information on airports, large and small, and other aviation facilities and procedures.
West Bend Municipal Airport is a city-owned public-use airport located three nautical miles (6 km) east of the central business district of West Bend, a city in Washington County, Wisconsin, United States. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023–2027, in which it is categorized as a regional reliever airport facility.
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. There are charts for all land masses on Earth, and long-distance charts for trans-oceanic travel.
In United States aviation, a sectional aeronautical chart, often called a sectional chart or a sectional for short, is a type of aeronautical chart designed for air navigation under visual flight rules (VFR).
Approach plates are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations. Each country maintains its own instrument approach procedures according to International Civil Aviation Organization (ICAO) standards.
The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations.
In United States and Canada aviation, terminal area charts are aeronautical charts intended for navigation under Visual Flight Rules that depict areas surrounding major airports, primarily those with Class B airspace.
This article describes the graphic conventions used in Sectional charts and Terminal area charts published for aeronautical navigation under Visual Flight Rules in the United States of America. The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration".
Ainsworth Regional Airport is seven miles northwest of Ainsworth, in Brown County, Nebraska. It is owned by the Ainsworth Airport Authority. The National Plan of Integrated Airport Systems for 2011–2015 called it a general aviation airport.
Aurora State Airport is a public airport located one mile (2 km) northwest of the central business district of Aurora, a city in Marion County, Oregon, United States. It is owned by the Oregon Department of Aviation.
Landing lights are lights, mounted on aircraft, that illuminate the terrain and runway ahead during takeoff and landing, as well as being used as a collision avoidance measure against other aircraft and bird strikes.
Sharpe Field is a closed private use airport located six nautical miles northwest of the central business district of Tuskegee, a city in Macon County, Alabama, United States. This airport is privately owned by the Bradbury Family Partnership.
Military training routes are aerial corridors across the United States in which military aircraft can operate below 10,000 feet faster than the maximum safe speed of 250 knots that all other aircraft are restricted to while operating below 10,000 feet. The routes are the result of a joint venture between the Federal Aviation Administration and the Department of Defense to provide for high-speed, low-altitude military activities.
Manila Municipal Airport is a public-use airport located two nautical miles northeast of the central business district of Manila, in Mississippi County, Arkansas, United States. It is owned by the City of Manila.
