TWR / TWR CDM

1. Introduction

1.1 General

The Swedish TWR profile makes use of advanced ground states and flight lists, this requires Euroscope v.3.2.1.27 or later.

Since TopSky is designed to be used in an Area/Approach setting the functionality of that setup is not suited for the tower environment. The tower setup is intended to be used only by DEL, GND or TWR positions (with or without an associated TMA). APP and CTR positions shall use the TopSky setup.

There are two versions of the tower setup, one for use at airports with A-CDM (Airport Collaborative Decision Making) and one for airports without. The tower setup uses EuroScope lists in a way similar to a FPB (Flight Progress Board A.k.a. Strips) where the progress of a flight can be managed.

1.2 Flight Progress Board

The FPB (Flight Progress Board) consists of default EuroScope lists arranged in a way that lets you monitor and manage the progress of a flight. Two TopSky lists, Sector and Uncontrolled, are also part of the setup and they will be used to handle airborne traffic. All lists in the FPB have columns and functions specific to that phase of flight.

A departing flight will appear in the Start-up list and will successively move to the Taxi Out list, Take-Off list and then to the Sector list. In the Start-up list you can manage any action necessary from receiving the flight plan to start-up and push-back. Once the aircraft calls for taxi the flight can be toggled to the Taxi Out list. When the aircraft receives the take-off clearance it will be toggled to the Take-Off list and once airborne it will show in the Sector list.

An arriving aircraft will initially appear in the Sector list and with less than 40 track miles to destination will also show in the ADC Sector list. The ADC Sector list will show the arrival sequence. Once the aircraft has landed it can be toggled to the Taxi In list.

Additionally, the setup contains the Uncontrolled list, showing all VFR flights, the Controller list and the METAR list. These lists are not forming part of the FPB.

Depending on what position you are working, you are encourage to remove lists that are unnecessary for your task. This will free up screen space and let you focus on the responsibilities specific to your working position. Below is a table suggesting which lists to have open for which position.

2. Ground Track Labels

This chapter describes the track labels as shown on ASRs using the Ground Radar plugin. For a description of TopSky track labels (such as shown on ESAA_TWR_APP.asr), see TopSky.

The track symbols and labels are colored according to the flight’s status (arrival, departure or overflight/unknown).

  • Arrivals are yellow
  • Departures are light blue
  • Overflight/unknown are light grey.

Data fields in normal text e.g. "SID", can be selected globally on/off via SETTINGS->Labels.
Data fields in bold text e.g. "CALLSIGN", is always shown
Data fields in parentheses e.g. "(ALRT)", are blank when there is no data.

Right-clicking on the any track symbol toggles the heading lines.
