Operation

2.4.1 Background

2.4.1.1

Type of

Touchscreens


Touchscreen Operation

Airfield lighting control for many years was accomplished at lighting control panels (referred to as an L-821) using toggle switches, rotary knobs, and pushbutton switches. Technology has changed and one of the changes has brought touchscreen monitors to the cabs of Air

Traffic Control Towers around the world. The Touchscreen is a very flexible tool for air traffic controllers and has reduced the amount of time they spend controlling airfield lighting.

The Touchscreen is basically a simplified operator interface tool. There are no need for keyboards and pointing devices such as a mouse or trackball. All of this is integrated right into the Touchscreen monitor.

The five-wire resistive touchscreens use a glass panel with a uniform resistive coating. A thick polyester coversheet is tightly suspended over the top of the glass, separated by small, transparent insulating dots. The coversheet has a hard, durable coating on the outer side and a conductive coating on the inner side.

2.4.1.2

Installation

2.4.1.3

Do’s and Don’ts

The touchscreen monitors may be Cathode Ray Tube (CRT) or Liquid Crystal Display (LCD).

The type will depend on the specific airport installation. The touchscreens are typically located in the tower cab, but can be located anywhere including maintenance centers or electrical airfield lighting vaults. The touchscreen can be rack-mounted, installed in an enclosure or put on a desktop depending on the application.

•

Always approach the buttons directly perpendicular to the touchscreen monitor face.

•

Remove finger at least one inch from the touchscreen monitor face before making another touch.

•

Always keep the touchscreen free of debris such as paper, dust etc.

•

Never touch the screen with wet hands.

•

Avoid spilling liquids onto the screen including water, coffee etc.

•

Never spray cleaner directly onto the touchscreen

2.4.2 Touchscreen Buttons

A touchscreen button is a rectangular area on the touchscreen that is colored differently from the background color, and responds to touch input by the user. A touch button’s color can change to indicate status. Touch buttons have two states, released and depressed.

Figure 1 shows two touch buttons, the right button is shown in the released state (also referred to as “up”), and the left button is shown in the depressed state (also referred to as

“down”). Note the difference in the shading of the borders of the two buttons..

Figure 1: Touch Buttons: Left depressed, right released

2.4.3 User Input

2.4.4 Touchscreen Pages

The released button (labeled UP) border colors are reversed from the colors of the depressed button borders. The depressed button (labeled DOWN) shows a dark black shadow on the top and left sides, with a bright white border on the right and bottom sides.

User input is accomplished by pressing any of the touchscreen touch buttons. The button will only respond when the monitor surface is touched directly on the button. This prohibits sliding into a button, as is the case with a raised mechanical button.

When the screen is touched, the conductive coating makes electrical contact with the coating on the glass. The voltages produced are the analog representation of the position touched.

The controller digitizes these voltages and transmits them to the computer for processing.

AccuTouch five-wire technology utilizes the bottom substrate for both X and Y-axis measurements. The flexible coversheet acts only as a voltage-measuring probe. This means the touchscreen will continue working properly even with non-uniformity in the coversheet's conductive coating. The result is an accurate, durable and reliable touchscreen that offers drift free operation. AccuTouch screens are sealed against contamination and moisture. This prevents wicking of fluid between the coversheet and glass.

Depending on the complexity of the airfield lighting control system, all necessary graphics and control buttons may not be able to fit on a single monitor screen. In this situation, the buttons and graphics are separated onto different “pages”. The term “pages” denotes the different graphics and button screens that a single touchscreen monitor can display.

Figure 2 is an example of a touchscreen page that will help to illustrate the layouts of the buttons. Take a look at the figure and find the locations of the Circuit Selection, Confirmation and Step Input buttons.

Selection Buttons



There are different types of touch buttons that have different functions depending on the airfield lighting control application. One type is the Circuit selection button. This button is directly associated with an individual airfield lighting group. Circuit selection buttons are used to choose the desired “lighting circuit” (i.e. 08R-26L Centerline lights) to control. An example is shown in Figure 3.

Figure 3: Circuit Selection buttons

Description

Description

Commanded

Commanded Step: The commanded step of the circuit is displayed at the bottom of the circuit selection button after the desired step selection is confirmed by pressing the

“CONFIRM” or “OK” button.

Button and graphics color: Once the step is confirmed, the button will change color and the associated airfield graphics will also change color indicating that the command has been recognized.

Alarm indication: If the circuit is in alarm, the button will change to red and the associated airfield graphics will also change to red.

If the lighting circuit is configured to operate on a 1-step CCR or on/off circuit, the brightness step button group will not appear after selecting the circuit. The user will either “CONFIRM” or “REJECT” the input.

If the lighting circuit is configured to operate on a 3-step CCR, than the step buttons have a direct correlation with the three (3) steps of the Constant Current Regulator (CCR). The step button group will appear on the touchscreen as seen in Figure 4.

If the circuit button selected controls a 5-step airfield lighting circuit, then the 5-step button group is displayed as seen in Figure 5.

Figure 5: 5-Step Control

2.4.9 Confirmation

Buttons

The confirmation buttons will appear after selecting the desired brightness step intensity.

These buttons offer the operator a final opportunity to accept or deny the touch inputs. These buttons are two (2) momentary touch buttons labeled “CONFIRM,” and “REJECT” as seen in

Figure 6.

NOTE: Some systems have them labeled as “OK” and “CANCEL”

Figure 6: Confirmation Buttons

2.4.10 CCR Ramping

2.4.11 Airport Operation

Status Field

To accept the inputs, press the “CONFIRM” button to send the pending command message to the ALCS system and make the airfield lighting change.

To deny the inputs, press the “REJECT: button. The touch inputs will be ignored and cleared from the touchscreen.

After either the “CONFIRM” or “REJECT” momentary touch button is depressed, the input step buttons are removed from display, and the affected circuit selector button automatically returns to the released state. The user must press both a circuit selector button and an input step button to modify lighting intensities.

The user may freely choose any lighting step regardless of the current step. The computer system will automatically “ramp” each CCR to the commanded step to eliminate stress to the

CCR and lights. The operator may command a lighting circuit directly to step five from the off state, and the computer will command the CCR(s) first to step 1, then step 2, then step 3 ... until the commanded step 5 is reached. The time delay between each successive step change is not less than 0.2 seconds and may be set longer for older CCR's that require more

“warm-up” time.

Located on each of the touchscreen pages is the airport operation status field. This field displays the current airport operation status. This reflects the last preset conditions that have been selected by the operator.

2.4.13 Touchscreen Mode and Time Field

•

Day / Night Setting: This represents the current setting for the Day and Night selection.

This is determined by the lighting preset selection.

•

Visibility Setting: This represents the current visibility setting for the airport. This is also

set by the lighting preset selection.

Another touchscreen option is the notification of sunrise and sunset occurrences.

The touchscreen is pre-programmed with the sunrise and sunset times for the installation location. When a sunrise/sunset time occurs, a full screen pop-up window is displayed, and the audible tone is sounded to notify the user of the event. The user must press the

CONFIRM button to acknowledge the event and silence the audible tone.

No automatic lighting changes will occur during this condition, this feature is to notify the user when it is time to change from a “DAY” setting to a “NIGHT” setting.

If your touchscreen control system does not have this feature and you wish to enable this option, please contact your local ADB Airfield Solutions sales representative.

Located on each of the touchscreen pages is the mode and time field. This field displays the current date and time and also the current operating mode of the touchscreen as seen in

Figure 8.

Figure 8: Mode and Time Field

2.4.14 Alarm Display and

Alarm Silence Buttons

The different operating modes are:

View Only: This indicates that the current touchscreen is operating as a view only station.

This means that the user can change between the different pages, but the touchscreen will not allow any touch inputs. The touchscreen will beep each time the screen is touched, but will not register the touch as a valid request.

Control Mode: This indicates that the touchscreen has full control capabilities. Any and all

valid touches and airfield lighting requests will be executed.

Demo Control Mode: This indicates that the touchscreen has simulated control capabilities.

The touchscreen will “act” as if it has full control capabilities and will accept touch inputs and update graphics. However, the touchscreen is completely isolated from the lighting control system and will not affect any airfield lighting changes. This mode is primarily used for training of ATC and maintenance on the operation of the touchscreen.

Located on each of the touchscreen pages is the alarm display and alarm silence button.

These buttons are used in conjunction with alarm conditions that are reported to the touchscreen. They operate as follows:

Alarm Silence (Alarm Acknowledge) Button is a button that flashes red when a new alarm

is present in the ALCS. It is pressed to silence the audible alarm and acknowledge the new alarm condition. Once an alarm is acknowledged, the button stays solid red until the alarm is cleared and an indication will then be logged in the database and viewable in the events log.

Alarm Display Button is a button used to view the current alarms in the computer system.

When pressed, this button will open the current alarms window which provides a text listing of all currently active alarms in the ALCS. It is useful for informing maintenance personnel of the exact alarm in the system.

The following section describes the layout and features of the touchscreen operator interface.

Included are directions to find your way around the many pages of the touchscreen interface and understanding the graphic representations of the airfields.

Each touchscreen control station is divided into several touchscreen pages. The number and name of the pages are airport specific.

CAUTION

For an exact representation of your airport, please refer to the touchscreen demonstration CD-ROM provided to your trainer. This CD-ROM has a fully functional touchscreen program that mimics your airport’s touchscreens and should be used in conjunction with this manual as part of your training.

The touchscreen pages are broken up into six (6) basic pages as follows:

1. Preset Page

2. Runway Page

3. Taxiway Page

4. Utility Page

5. Power Page (OPTIONAL FEATURE)

6. Stopbar Page (OPTIONAL FEATURE)

The preset page is the primary used page that all lighting command changes should normally take place.

Preset controls are developed in conjunction with FAA Document Number 7110.65 and the airport. The FAA 7110.65 document defines what intensities 1-step, 3-step and 5-step circuits should be at during all levels of visibility and day or night conditions.

Preset controls are initiated at the “Preset Page” of the touchscreen and when confirmed, execute several lighting commands based on the preset inputs. The preset controls are developed to reduce ATC workload and decision making that involves the airfield lighting circuits.

Preset circuits do not allow the user to specify a specific intensity selection, rather the user inputs the airport’s current operating conditions, such as RVR (Visibility) conditions, CAT conditions, Day or Night operation and operating Runway directions. The intensity settings for the selected conditions are “looked up” from a preset look-up table, which is a preprogrammed table in the operating code of the touchscreen. Preset intensity look-up tables are not user alterable.

After a preset condition has been confirmed, the ALCS system then performs several lighting changes to match the requirements for the airport.

Active Runway Selection: These buttons select which runway or runway direction is desired

for airfield operations. Multiple Runways may be selected depending on the airport.

Day / Night Setting: These buttons select between “DAY” airfield operation and “NIGHT”

airfield operation. This setting will affect the brightness intensity of the lighting circuits.

2.5.3 Runway Page

96A0270 Rev. H

5/1/13

The circuit buttons on the runway page are used to manually override any commands that were initiated by the preset commands. On the “Runway Page” the user can selectively adjust the lighting of individual runway circuits.

CAUTION

If lighting changes are done using the “Runway Page” they may not meet those required for the airport’s operating conditions. If circuits are individually turned on using the “Runway Page” there is the possiblity that they may be inadvertently turned off if an ATC uses the “Preset Page” to change the lighting. For example, if the runway lights were individually turned on the Step 5 using the “Runway Page” and then an ATC selected “Day”, “> 5 miles” visibility, the runway lights would turn

OFF.

It is recommended to always use the preset controls for adjusting lighting intensities.

96A0270 Rev. H

5/1/13



2.5.5.6 Request Control Button

The ‘REQUEST CONTROL’ button only appears on remote computer locations such as the lighting vault, maintenance center and operations center. It will only appear at those locations that have been authorized to have remote control access. Once a remote location has requested control of the lights, the

ATC has to authorize the control using the ‘CONTROL AUTH’ button as seen in Figure 20 below.

Figure 20: Control Authorization

However, in some instances, control authorization is not required by ATC for a remote location to gain control of the airfield lighting. This is an optional feature of the ALCS is available at the request of the airport/ owner.

To request control of the airfield lighting from a remote computer equipped with this option…

1. Select the “REQUEST CONTROL” button from the ‘UTILITY PAGE’.

2. Enter the correct username and password then select ‘ENTER’

3. A screen will momentarily pop up, as seen in Figure 21, this indicates that the request has been recognized.


21



Figure 21: Request Control Window

96A0270 Rev. H

5/1/13

1. You now have 60 seconds to contact the ATC and have them execute the ‘CONTROL

AUTH’ function as previously discussed.

2. If the ATC grants control within the 60 second time period, the window will disappear and the computer will have control of the airfield lighting.

At this point, the computer at the remote subsystem will change from "VIEW ONLY" mode to

"CONTROL" mode and the user will have control of the airfield lighting.

If your computer does not require authorization from the Tower ATC (as requested by the airport/ owner), then that computer will immediately gain control from the tower after the correct password was entered.

How does Remote Control Work?

Once a remote subsystem has taken airfield lighting control, the commands from that location are sent to the lighting vaults similar to how the ATC tower control the lights.

How do you give Remote Control back to the Tower?

Personnel can give control back to the tower by simply touching the ‘REQUEST CONTROL’ button again and entering the correct password. This procedure will put that subsystem back in "VIEW ONLY" mode and will give control back to the ATC tower.

Another method is to simply exit the touchscreen session at the Vault or Maintenance Center by selecting the “EXIT TO MAIN MENU’ button from the ‘UTILITY PAGE’

2.6.1.2 Failsafe

The ALCS system reports alarms of critical nature to the touchscreen operator interface.

Alarms related to airfield lighting circuits will cause the corresponding graphic to change to red, the associated circuit selector button will be red, the audible alarm sounds, and the

ALARM SILENCE button begins to flash.

The alarms can be viewed by pressing the “ALARM DISPLAY” button on any touchscreen page. The alarm log will appear and display a text listing of the current active alarms in the

ALCS.

This listing is accessible at any ALCS subsystem location, and airport maintenance personnel will be familiar with the meaning of each alarm text. The extent and repair of each alarm condition is discussed in the ALCS Maintenance Manual.

WARNING

Not all alarm conditions will be reported to the Touchscreen at the ATC Tower.

The airport / owner has determined what alarms should be reported to the tower touchscreen. What alarms are reported will be discussed as part of your training.

The audible alarm is configured for a five (5) second delay. After sounding for 5 seconds the audible alarm is automatically silenced. The “ALARM SILENCE” button continues to flash and the associated circuit graphics remains red. This sequence will repeat after 60 seconds if the ‘ALARM SILENCE’ button is not pressed.

The user then must depress the “ALARM SILENCE” button to stop the button from flashing.

The user then has the option to view the alarms display screen to determine the exact cause of the alarm.

The ALCS system features a failsafe function that assures a safe a proper failure state of the system in the event of a communication or computer failure.

The failsafe state of the system is to remain ‘LATCHED’ to the last commanded state by ATC.

When the system is in a failsafe, a window will appear describing that the system is in failsafe. The window will automatically disappear once the failsafe condition has been cleared.
