- - This is a notice to our software users - -

January 1, 2009 - January's data and software release has incorporated several new advancements in the Airspace^® software. Below you will find a more detailed description of a few of the new advancements as well as example screen shots.

How to Setup the User Account

Applying Exception Criteria in Airspace  

Example 1

Example 2

Example 3

When the Airspace window is launched, you will notice a few changes to the standard user interface. The "User" field will allow the name of the individual performing the Airspace analyses to be listed on the printed reports once Airspace has been completed. Please see the "How-to Setup User Account" section below for additional details.

Additionally, we have added a feature to specify whether a structure will be studied as a "New Construction," "Alteration" or an "Existing Structure."  Depending on the selection chosen from the drop down list, Airspace will automatically turn on selection elements to allow for a more customized analysis of a site location. These elements were also added to take advantage of the FAA co-location policy and FAR Part 77.15 exceptions. The proper application of these parameters can identify if the antenna meets any exceptions covered in these publications that remove the requirement of filing with the FAA. Please see the "Applying Exception Criteria in Airspace" section below for additional details.

In order to take advantage of the "User" feature and include the individual's name on the completed Airspace Analyses printed reports, follow the steps listed below to set the User Name Field.

Step 1: Select File

Step 2: Select System Setup to access the setup screen.

Step 3. Once the User Setup window is visible, enter the user's name and information in the text boxes, then click OK. The data entered will be stored on the computer and accessed for subsequent analyses. If the individual changes, the previous steps will need to be repeated.

In order to take advantage of the FAA Co-Location policy or the FAR Part 77.15 exceptions, the proposed structure must be an "Alteration" to an existing structure or be an "Existing" structure. If the proposed structure is new construction or an alteration to an antenna tower, which will result in an increase to the antenna tower's height, the described exceptions to avoid filing notice with the FAA cannot be applied, and the structure must be studied as "New Construction."

In this example we will walk through a study with the following parameters:

	An antenna will be added to the top of an existing structure that is not an existing antenna tower.
	The antenna will emit frequencies in the following bands: 935-941 MHz and 1670-1675 MHz.
	The existing structure does not have a valid FAA Aeronautical Study Number (ASN).
	The proposed antenna will not increase the structure by more than 20'.

Step 1: Select "Alteration" from the drop down list box.

Step 2: Once selected, the Frequencies button becomes activated. If the antenna will be transmitting in specific frequency bands, it will be necessary to confirm if the frequencies are contained within the approved bands by selecting "Yes" or "No."

Step 3: The last step is to select "Antenna 20' or less". Doing so automatically selects the "Alter Height" checkbox.

Step 4: Once all of the options are selected, finish by entering the geographical data, ie. coordinates, ground elevation and structure height. Click the Check Button and run the analysis as normal.

In this example we will walk through a study with the following parameters:

	An antenna will be added to the top of an existing structure that is not an existing antenna tower.
	The antenna will emit frequencies in the following bands 935-941 MHz and 1670-1675 MHz.
	The existing structure does have a valid FAA Aeronautical Study Number (ASN).
	The proposed antenna will not increase the structure by more than 20'.

Step 1: Perform the same steps as the previous example by selecting or deselecting the parameters specific to this site analysis. In this case we selected "Existing DNH", "Antenna 20' or less" and entered the valid FAA Aeronautical Study Number (ASN) into the text box.

Step 2: Once all of the options are selected, finish by entering the geographical data, ie. coordinates, ground elevation and structure height. Click the Check Button and run the analysis as normal.

In this example, we will walk through a study with the following parameters:

	An antenna will be internal to an existing structure that is not an existing antenna tower.
	The antenna will emit frequencies in the following bands: 935-941 MHz and 1670-1675 MHz.
	The existing structure does have a valid FAA Aeronautical Study Number (ASN).
	The proposed antenna will not increase the structure by more than 20'.

Step 1: Perform the same steps as the previous example by selecting or deselecting the parameters specific to this site analysis. In this case we selected the "Existing DNH" and the "Internal" checkboxes.

Step 2: Once all of the options are selected, finish by entering the geographical data, ie. coordinates, ground elevation and structure height. Click the Check Button and run the analysis as normal.
