Airports, Flight and Upper Information Regions and Favorite airports 

This will cover the use of the navigation layer. 

We estimate that this will take 3 minutes to complete.

Navigation Layers

The Navigation layer will allow you to turn on important navigational information:
 

        Flight Information Regions (FIR) / Upper Information Region (UIR): Flight information boundaries will be displayed on the map with detailed information.

        Grid Moras: This is currently a work in progress so we will not be talking about this in this topic.

        Airports: Displays all the airports with detailed information.

        Favorite airports: This will allow you to create a selection of your favorite airports that will be shown on the map.
 

The following points will be explained in a separate topic.
 

        High/Low

        Airways

        Waypoints

        Holdings

        Navaids

        Restrictive Airspace

        Controlled Airspace

2       Detailed Explanation 

Let's start by having a look where we can access the navigational layers 

Interaction 1

Interaction 1 Click the Layers button.

2.1        Flight/Upper Information Regions 

  

To access the NAV layers you need to make sure that the tab has been selected and highlighted.

Interaction 1

Interaction 1 Click the FIR/UIR slider.

Layers will only be visible and will be able to be turned on and off at certain zoom levels. Currently grid moras will not be accessible as it is greyed out, zooming in will activate the slider.

Let's start with looking at the flight information region (FIR) and upper information region (UIR). You can see on the map that it has been split up into different boundaries these are called flight information regions and are a specified region of airspace in which a flight information service is provided.

Interaction 1 Please click Next to continue. 

If you zoom out too far you will loose your FIR/UIR boundaries. You will need to zoom back in to retrieve it.

Some countries split their FIR/UIR to make controlling the airspace easier, for example the United Kingdom has split it into a north and south, other countries might have a single FIR. Let's look into an FIR for more information.

Interaction 1

Let's look at this FIR over Germany to start with. Clicking within the FIR will bring up a list of all the possible FIRs. 

Interaction 1 Click the within the circle image.

A list will be generated from your chosen FIR. In this case there are a possible two FIRs to choose from.  

Interaction 1

The FIR ICAO code will be shown in the list, the code is the main governing state that controls that area. Let's look at EDGG which is Germany.

Interaction 1 Click the FIR EDGG list item.

Interaction 1

Opening the FIR will highlight the selection in orange that the chosen area covers. This is particularly useful should you have multiple FIRs on top of one another covering the same area.

   

Information about the FIR with important details such as the altitude limits and any entry clearances. Let's now look at the second FIR.

Interaction 1 Click the FIR EDVV list item.

You can see that the highlighted area has now changed to resemble the second FIR EDVV. This FIR type is a UIR, as mentioned in the details under type.

   

Interaction 1

Let's zoom out to see what happens to the FIRs.

Interaction 1 Click the zoom out button.

Interaction 1

Your highlighted FIR will remain at any zoom level, all other FIRs will be removed as they only show at certain zoom levels.

The FIR will not change if you choose another FIR from the list at this zoom level. You will need to zoom back in to show all the FIRs to change your selection. 

Closing the FIR or clicking on anywhere on the map will remove the FIRs.

   

Interaction 1 Click the Close button.

On closing the list down you can see that the FIRs are not visible anymore, even though we have not turned off the FIR/UIR button. Let's zoom back in.

Interaction 1

As you still had FIR/UIR slider turned on, zooming back in will bring up the FIRs again. Let's now turn off the FIRs. 

Interaction 1 Click the FIR/UIR slider.

All airports are indicated with a cog symbol . Zooming in will give you a clearer image of the aerodromes. Let's have a look at one of them in more detail.

Interaction 1 Click the Save button.

Typing the aerodrome on top of one another as shown or next tow each other (egkk,lfpg) will also work. You cannot input either the name of the airport (Gatwick) or join up the ICAO codes (egkklfpg) these will not work and will not be shown on the map.

Once saved, you will need to refresh the favorite airports slider so your two airports will be visible.

As you can see we have airports and favorite airports turned on. Favorite airports will sit on top of the airports.
