As with the SIDs and STARs questions will be set in the examination on selected Approach Charts. Students are advised to become as conversant as possible with the layout and content of this comprehensive legend. The subdivisions of this legend, which are a potential source of examination questions, are:

•Landing Minimums.

•Airport Chart Format and Plan View.

•Additional Runway Information.

•Lighting Systems.

•Take-off and Alternate Minimums.

•GPS Approach Charts

•ICAO recommended airport signs and runway markings.

Air Traffic Services (ATS) Routes/Standard Routes

(Ref: Current UK AIP ENR 1 and ENR 3)

In the United Kingdom ATS Routes are based upon significant geographical points which may or may not coincide with the location of a radio navigation aid. These significant points can be found in column 1 of the table at ENR 3.

Unless stated otherwise an airway is 5 NM either side of a straight line joining each two consecutive points shown in column 1 of the table. Upper ATS routes and Advisory Routes have no declared width but for the purposes of ATS provision are deemed to be 5 NM either side of a straight line joining each two consecutive points. The vertical extent is shown in column 3 of the table.

ENR 3 is divided into:

•LOWER ATS ROUTES which have an upper limit of FL245.

Ref. E(LO)1: See B1 ATS route, 279 and 085 radials from WAL VOR/DME at N5323.5 W00308.0.

•LOWER ATS ROUTES - (ATS ADVISORY ROUTES). These have a maximum upper limit of FL240. The route designator for an Advisory Route always ends with D, e.g. A1D, N562D. Ref. E(LO)1: See W911D Advisory Route, 242 and 058 radials from IOM VOR/DME N5404.0 W00445.7

Note: Advisory Routes, class F airspace, are thus not established within Controlled Airspace and are designated routes along which Air Traffic Advisory Service is available. An Air Traffic Advisory Service is a service provided within advisory airspace to ensure separation, in so far as is practical, between aircraft which are operating on IFR flight plans.
