Area control centers (ACCs) control IFR air traffic in their flight information region (FIR). The current list of FIRs and ACCs is maintained by the International Civil Aviation Organization (ICAO). [1] Note that the cited ICAO source gives the shapefile coordinates for each FIR, and also its page source gives a list of current ACCs in text form.
(VFR squawk code for airspace above 5,000 feet (1,500 m) – prior to 15 March 2007 when replaced by the international 7000 code for VFR traffic.) [5] 0025 Germany: Parachute dropping in progress. [citation needed] 0033 UK: Parachute dropping in progress. [2] 0041–0057 Belgium: Assigned for VFR traffic under Flight Information Services (BXL FIC).
Military aircraft also use a dedicated UHF-AM band from 225.0 to 399.95 MHz for air-to-air and air-to-ground, including air traffic control communication. This band has a designated emergency and guard channel of 243.0 MHz. [2] [8] Radio aeronautical navigation aids use other frequencies.
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 ...
A map showing the borders of the United States' flight information regions as well as that of Canada and other neighboring nations. Old Federal Aviation Administration airspace map of ARTCCs in the United States overlaid with what states they cover Flight Information Regions (FIR) of France FIR and jurisdictional airspace in Japan FIR and jurisdictional airspace in South Korea
Common traffic advisory frequency (CTAF) is the name given to the VHF radio frequency used for air-to-air communication at United States, and Australian non-towered airports. Many towered airports close their towers overnight, keeping the airport open for cargo operations and other activity.
Regulation of airports and aviation in the Philippines lies with the Civil Aviation Authority of the Philippines (CAAP). The CAAP's classification system, introduced in 2008, rationalizes the previous Air Transportation Office (ATO) system of airport classification, pursuant to the Philippine Transport Strategic Study and the 1992 Civil Aviation Master Plan.

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). In Australia, Canada and some other countries, the equivalent charts used for visual flight are called VFR Navigation Charts (VNCs).
