No Binding. Condición: Very Good. Colour map 84x55cm. Very good, folded, with crinkling to the paper. Fifth Edition, corrected to 13 January 1958. This would have provided important practical information to the RAF in navigating the region, with the British retaining significant political, military and economic interests in the Gulf and South Arabia post-Suez, with several RAF bases forming part of their defence. ATC Charts demarcate airspace and reporting points to support navigation and communications during the flight. As they do not show international boundaries or many other geographical features, they include a warning not to use them for plotting purposes. At their broadest level, they divide coverage into Flight Information Regions (FIR), whose boundaries at times follow international boundaries though stated not authoritatively, and mostly tend to be named after prominent locations within them. In this case the FIRs are Teheran, Bahrain, Aden, Baghdad, Damascus, Easternmed, Istanbul, Khartoum, Cairo, Fort Lamy, Malta, etc. Within the FIRs are Control Zones, Control Areas, and Advisory Areas. Airways and Advisory Routes are drawn as a complex web of interconnecting labelled air corridors intended to maintain smooth traffic flow and keep pilots within the authorised areas. Compulsory Reporting Points to assist navigation are marked, including non-directional beacons, radio ranges, fan markers, others, along with geographical locations within the corridors.

Later edition, corrected to 1958, of this chart showing flight paths around the Middle East and North Africa. Major air traffic control hubs are coloured in blue, with compass bearings, compulsory reporting points, and radio ranges marked in black. The boundaries of each flight information region are also clearly marked. RAF pilots would use these charts to avoid civilian flight paths, so they needed to know who the relevant local authority was in any given area. This allowed them to radio in reports or requests for information to the correct controllers. Sometimes these authorities stretched far beyond the national borders of the country itself, such as Malta spanning most of North Africa or Bahrain over Saudi Arabia. This example is the fifth edition. Colour chart (546 x 845 mm), printed on recto only. Initials inscribed in blue ink on one panel. Chart bright, a little soiled especially to two lower right panels: a very good example.

Colour-printed map, 845 x 545 mm. An RAF air traffic control chart from the early days of regular civilian flight in the Middle East. Meant entirely for the use of pilots and controllers, air traffic control charts do not show international boundaries or geographical information beyond coastlines, and instead are sectioned into flight information region boundaries, control and advisory zones, civilian flight paths, and various beacons, radio ranges, and other compulsory reporting points. RAF pilots did not always use civilian airspace, and would use a map such as this to avoid wandering into heavily trafficked areas and upsetting carefully arranged and scheduled flight paths. However, pilots were expected to announce their position to the relevant local authority on the ground, and used maps like this one to know to whom to report, or to ask for information on weather, emergency landing options, and other daily necessities. For example, a pilot flying over the Arabian Gulf would consult this particular map and see that they were in the boundary of air traffic control in Bahrain, regardless of the true international boundaries below, whether they were flying over certain parts of Saudi Arabia, the sheikhdoms which would become the United Arab Emirates, Qatar, or Bahrain itself. - Only the most minor hints of wear; well-preserved.
