4 CHAPTER 1 GENERAL 1.1 INTRODUCTION ICAO has recommended the development of provisions for remotely-operated Air Traffic Services (ATS), for surveillance and communications, providing requirements for sensors and display technologies to replace visual observation, and providing requirements for personnel licensing and training [1]). including updating requirements The use of remote tower technology enables the provision of aerodrome ATS as defined in ICAO Document 4444 [2], EUROCONTROL’s Manual for Aeronautical Flight Information Service (AFIS) [3] and ICAO Document 9426 [4] from a location from which provision of ATS by direct visual observation is not possible. A remote tower facility could be several hundred kilometres from the aerodrome it is providing service to, or it could be located in a building on or near the aerodrome but without an adequate direct view of the area of control responsibility. ICAO Document 9426 (Part III) [4] states that an aerodrome tower is required to “permit the controller to visually survey those portions of the aerodrome and its vicinity over which they exercise control”. In the switch from a conventional tower to a remote tower facility, the primary change relates to the manner by which the above provision is satisfied. The view from a conventional tower (the "out-of-the-window" (OTW) view) facilitates visual survey in line with the ICAO regulation. When operating from a remote tower facility, visual observation of the aerodrome is no longer carried out by directly observing the OTW view. Instead, a remote tower optical system, comprising cameras at the aerodrome and a display presentation to the remote operator, are provided to enable situational awareness. The remote tower visual presentation is one of the principle components that enables the provision of ATS from a remote tower facility or from environments where an existing aerodrome tower OTW view is inadequate for providing ATS. An optical sensor presentation is a type of visual presentation that displays video images from cameras, which could be infrared as well as visible spectrum devices. This Minimum Aviation System Performance Specification (MASPS) document pertains to remote tower optical systems, and is applicable to all optical sensor configurations that could be used to implement remotely-operated ATS for an aerodrome. The specific configuration of the optical system will be a matter for individual implementations. 1.2 DEFINITION OF TERMS NOTE: Some terms provided below are taken from ICAO documents, EASA Annex to ED Decision 2015/014/R or SESAR Documents [2][6][11]. The following defined terms are used within the context of this document. Air Traffic Services A generic term meaning variously, flight information service, alerting service, air traffic advisory service, or air traffic control service (area control service, approach control service or aerodrome control service). Johnson’s Criteria Detection Something in an image that raises an observer’s attention. Johnson’s Criteria Military example: “There is something!” [12] Visual Detection in ATS based on Johnson’s Criteria Detection Johnson’s detection criteria applied to images of objects relevant to the provision of ATS displayed in a visual presentation. Same as for Johnson’s criteria detection: “There is something!” © EUROCAE, 2016 Copyright European Organization for Civil Aviation Equipment Provided by IHSOrder Number: W2096771Sold to:SECOND INST OF CIVIL AVIATION [220619100001] - XHE_NCEPU@163.COM, Not for Resale,2018-05-29 16:54:43 UTCNo reproduction or networking permitted without license from IHS--````````````,`,,,,,``-`-``,```,,,`---
5 Johnson’s Criteria Recognition Classes of objects can be differentiated. Johnson’s criteria military example: Tank/Armoured Personnel Carrier/Lorry [12]. Visual Recognition in ATS based on Johnson’s criteria recognition Attributes of an object relevant to ATS provision that may be perceived based on Johnson’s criteria recognition applied to its display in a visual presentation. Such attributes include the following:  Class / category / type of aircraft: to be determined based on, for example, one or more of the following:       Aircraft size & fuselage configuration Engine configuration (e.g. wing-mounted (below/above) or tail- mounted, number and type of engines) Wing configuration (e.g. wing mounted below or on top of the fuselage) Stabilizer configuration Landing gear configuration Aircraft painting or markings   Vehicle type / class: e.g. fire truck / car / fuel truck / baggage trailer Personnel and obstructions: e.g. person / wildlife / FOD Visual Presentation A visual display that shows the areas of responsibility of the remote tower ATS Unit. The term “visual presentation” comprises the following types of presentation (as used in the context of this document): a) b) c) optical sensor presentation virtual presentation augmented presentation a) Optical Sensor Presentation Display of images from optical sensors (visible spectrum, thermal, IR, NIR, SWIR …). NOTE: Implementations of the optical sensor presentation at the time of writing of this MASPS typically comprise a wide-angle display (‘panorama’) that presents a wide field-of-view image derived from one or more fixed-view optical sensors, and a PTZ view. Panorama The term ‘panorama’ is used in this MASPS to refer to a wide-angle display typically used to show images from fixed-view optical sensors. However, use of this term does not preclude other implementations of the optical sensor presentation. PTZ An imaging sensor or sensors with a pan/tilt pointing capability and a narrow, possibly variable, angle of view. The PTZ sensor and view emulate the function of binoculars in a conventional tower, and could also be used to assist light gun operation. © EUROCAE, 2016 Copyright European Organization for Civil Aviation Equipment Provided by IHSOrder Number: W2096771Sold to:SECOND INST OF CIVIL AVIATION [220619100001] - XHE_NCEPU@163.COM, Not for Resale,2018-05-29 16:54:43 UTCNo reproduction or networking permitted without license from IHS--````````````,`,,,,,``-`-``,```,,,`---
6 b) Virtual Presentation A computer-generated synthetic visual representation of the aerodrome operational environment generated using target information derived from surveillance systems (e.g. multilateration, ADS-B, approach radar), static environment information (e.g. aerodrome layout, GIS data) and other sensor information (e.g. meteorological data). The virtual presentation may contain two- dimensional, three-dimensional, pictorial, symbolic or textual representations. NOTE: This definition includes two-dimensional plan-position indicator type displays as well as three-dimensional virtual environments. c) Augmented Presentation A mixture of virtual presentation and optical sensor presentation, whereby information associated with real-world objects is presented as 2D/3D graphical elements, image data, symbols or text overlaid onto the optical sensor presentation, either conformably or close to their optical images. Examples include runway/taxiway boundaries and stop bars, and target symbols and labels. Operator Throughout this document, the term “operator” is used to refer to the officer providing ATS in the role of ATCO, AFISO or apron controller. Out-The-Window (OTW) view The view from a conventional aerodrome tower’s visual control room. Remote Tower Module (RTM) A module from which Remote ATS can be provided. It includes one or more controller working positions (including necessary ATS systems such as communications, aerodrome lighting control etc.) and visual presentation display screens, as required. (CWPs) Remote Tower Centre (RTC) A facility containing one or more RTMs from which ATS can be provided to one or more aerodromes. 1.3 ABBREVIATIONS AFISO ATC ATCO ATM ATS DLR TABLE 1: ABBREVIATIONS Aerodrome Flight Information Service Officer Air Traffic Control Air Traffic Control Officer Air Traffic Management Air Traffic Services Deutsche Zentrum für Luft- und Raumfahrt e.V.
