2 Information Systems
2.1 Meteorological Information Display
A display clearly showing current and relevant meteorological information shall be provided (12).
2.2 Surface Wind Indication Displays a) Control positions are to be equipped with surface wind indicator(s) simultaneously
showing speed and direction (13).
b) At aerodromes supporting scheduled journeys (as defined in the Air Navigation Order, Article 255) by aircraft whose maximum total weight authorised exceeds 5,700 kg and such other aerodromes as the CAA may direct, control positions are to be equipped with a surface wind indicator capable of giving surface wind information in accordance with ICAO Annex 3, Meteorological Service For International Air Navigation (see Part C, Section 4, MET) (14).
c) Where control positions are adjacent it may be possible to share displays.
2.3 Siting of Wind Sensors
Surface wind sensors are to be located on the manoeuvring area in compliance with the CAA’s current siting and exposure requirements as described in Part C, Section 4, MET and CAP 746 Meteorological Observations at Aerodromes (15).
2.4 Pressure Setting Information
2.4.1 Pressure measurement equipment or a method of obtaining pressure setting (16), and an indicator displaying pressure setting are to be provided (17). The required accuracy of measurement or observation shall be ± 0.5 mb (hPa) (18). Detailed information can be obtained from CAP 746 and ICAO Annex 3.
2.4.2 Suitable training in the use of meteorological equipment must be provided if meteorological information is not provided by a third party meteorological data service provider (1744).
NOTE: ATS staff may be involved in the provision of meteorological information, but for the purposes of safety regulation this function is deemed not to be subject to regulation by the SRG Air Traffic Standards Division. The meteorological service to aviation is subject to regulation by the UK Meteorological Authority; see Part C, Section 4, MET for further details.
2.5 Serviceability Indicators
There must be either:
a) An indicator showing the serviceability status of any navigation or approach aid provided for the use of aircraft flying to or from the aerodrome (20); or
b) A method of communicating with the engineer responsible for the serviceability of such equipment (21). This method of communication is to be detailed in the MATS Part 2 (22).
3 Visual Control Room (VCR)
3.1 The Visual Control Room shall be sited so as to permit the controller to survey those portions of the aerodrome and its vicinity over which he exercises control (23). The most significant factors contributing to adequate visual surveillance are the siting of the tower and the height above ground of the Visual Control Room.
3.2 Providers should consider the impact of control tower building developments on other CAA requirements such as those of the aerodrome licence (e.g. safeguarding).
3.3 Providers must safeguard the view from an existing Visual Control Room from obstruction (24). The view from an existing Visual Control Room might be obstructed because of poor site selection, an extension of the manoeuvring area or by the construction of buildings close to the control tower.
3.4 When informed of proposals which may affect the view from the control positions the Provider shall identify operational and functional requirements. From these, safety requirements can be drawn up which will ensure the controllers’ view remains unhindered as described above. In setting these safety requirements Providers should consider such things as:
