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.
