1 System Features
1.1 Does London Control use voice recognition?
The main London Control package does include voice recognition and allows clearances and instructions to be passed to aircraft by voice commands. Go to the voice recognition page for more information.

1.2 How are clearances and instructions input into the system?
The system uses on-screen pop-up menus for input of instructions and clearances to aircraft. It uses exactly the kind of HMI techniques that will come into operation in real ATC systems in the not-too-distant future. (Currently there are very few truly electronic ATC systems. Most still use paper strips, and even those without strips still make very little use of electronic support.) The advanced tools rely on the input of clearances so that the system knows what the aircraft have been instructed to do. Real controllers will be operating in exactly this manner before too long, when they get the kind of advanced tools that London Control already includes.

1.3 Does the system simulate radio messages between air and ground?
London Control simulates highly realistic R/T sound in response to input instructions, as well as other messages from aircraft.

1.4 Can I print paper flight strips from London Control?
London Control includes the ability to print paper flight strips.

1.5 Does London Control allow me to co-ordinate traffic with other sectors and units?
Yes, the system includes a very sophisticated co-ordination function. Each flight must be co-ordinated into and out of the sector being controlled. Many of these co-ordinations are automatic, as 'standing agreements' are used to reduce the workload of controllers.

1.6 How does London Control enable one person to carry out both the planning and tactical controller roles at the same time?
Although the system is highly realistic in the way that it supports the different controller roles, some simplifications have been included so that one person can do the entire job of controlling one sector. The advanced tools help with this considerably. It is also possible to set the system into a mode where coordination is no longer required, so the planning task is reduced almost to nothing.

1.7 Does London Control interface to flight simulator software?
No, London Control does not interface to any flight simulators. It is designed as a stand-alone simulation of air traffic control.

2 Help and Documentation
2.1 Does London Control have help that I can access when the program is running?
Context sensitive help is available through menu options or the <F1> and <F2> keyboard keys.

2. 2 I don't seem able to open the help files from inside the program.
Run-time help uses the HTML Help program that is a standard feature of Windows 98, 2000 and XP. However, it is possible that it has not been installed, or the installation is no longer functioning. If necessary, the HTMLHelp program can be downloaded from the Microsoft website at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/hwMicrosoftHTMLHelpDownloads.asp

2.3 I don't seem to be able to open any of the help documents from outside the program.
The help documents (User Guide, Sector Information Manual and Maps) are PDF files and require Adobe Reader to open them. Adobe reader can be obtained from the Adobe website. (Adobe Reader was formerly called Acrobat Reader)

2.4 When I try to open the User Guide or Sector Information Manual, Adobe Reader complains that it cannot open them.
The documents have been produced for Adobe Reader version 6.0 or later. Although some earlier versions can open them, they may not appear correctly. It is best to use the latest version of Adobe Reader. (Use the button on the left of this page.)

2.5 Can I print the London Control documents?
Yes, provided they are for your own use. Bear in mind that the documents are large (the Sector Information Manual is over 300 pages). It may be best to only print those sections that you will need to refer to frequently (for example, the sections of the SIM relating to the sectors you are currently training on).

3 Installation and Running
3.1 The system seems to run very slowly, what can I do to improve performance?
There are a number of options that can be set-up in the User Preferences to reduce the processing requirement of the system. These include: switching off MTCA and STCA, setting the Scan Segments to a low number (one, if necessary), switching off vector lines and halos, and not using radio communication. Also, do not have other large applications running at the same time as London Control.

3.2 When I change the sound volume for the radio using the Radio Control Menu, it doesn't seem to make any difference.
The Radio Control Menu allows the volume of the radio sound to be adjusted. However, each computer tends to have a number of different sound controls in its mixer that can override the volume control. Experiment with your computers volume controls to achieve a satisfactory setting.

3.3 When London Control starts-up, the introductory animation doesn't play.
Check that the animation hasn't been switched off in the Log-On Window. Also, the animation file (Intro.avi) may have been removed to save disk space. Finally, your system may be missing a standard video codec. These can be installed from your Windows installation, or downloaded from the Internet.

3.4 Is London Control available for download from the website?
London Control is now available for purchase by download from our website. Instructions on how to download and install the software will be given by e-mail after purchase. P
lease note that orders will be subject to manual processing, so please allow at least 24 hours for download instructions to arrive. Also, the 'Download' shipping zone must be selected in the shopping cart, so that the shipping charge will be correct (zero).

4 Adaptation Data
4.1 What airspace does London Control cover?
London Control simulates the London Flight Information Region, which covers the airspace over England and Wales. It only includes data for this area. It simulates the sectors of London Area Control, London Terminal Control, both based at Swanwick, and the Manchester area control sectors, based at the Prestwick.

4.2 Can London Control be adapted to cover other countries' airspace and their ATC centres?
Yes, the system has been designed so that it can use data for other countries and ATC centres. Enthusiasts in other countries are able to develop data files for their local areas. We will provide assistance to any individuals or groups who would like to do this, such as documentation for the adaptation data files, and access to utilities to check that they will work. We have produced data for the Scottish FIR ourselves, and this can be downloaded from here.

4.3 What does an update contain?
An update provides a new set of data files for the London FIR (we call this LCData). These new data files will bring London Control up-to-date with any changes to the airspace and ATC procedures. If you subscribe to updates you will also receive with them any updated versions of the program files for version 1 of the system.

4.4 What is the difference between an update and an upgrade?
An update just updates the data files (LCData), and provides updates to the version 1 program. An upgrade is a new version of the complete system (eg version 2). Subscribing to updates will not entitle you to free upgrades. However, any future upgrades will be available to existing purchasers at a reduced "upgrade" price.

4.5 Why do I have to subscribe to get updates to the data?
The production and maintenance of the data files (LCData) is a significant undertaking, almost as costly and time-consuming as the writing of the software. Unfortunately, we must pass this cost on by charging for each update.

4.6 When I install an update, must I have installed previous updates?
No. Each update contains the full set of data required to update the originally delivered system. In this way, it is possible to purchase just the occasional update package to keep fully up-to-date.
