FLT ADDITIONAL INFORMATION

On this page you can find additional information related to how certain FLT parameters work, as well as some tables containing values that are required by some FLT parameters.

 

 

Universal Screen Co-ordinates

Universal screen coordinates is a system designed to make screen positions independent of screen resolution. The universal coordinates extend from (0, 0) in the top left hand corner to (8192, 6144) in the bottom right hand corner. So, for example: If the universal coordinates of a rectangle are (500, 400) and it has a width of 7192px and a height of 650px and the screen resolution is 1024x768px, then the actual screen coordinates and size of the rectangle would be calculated as follows:

X = 500 * (1024/8192) = 62.5
Y = 400 * (768/6144) = 50
W = 7192 * (1024/8192) = 899
H = 650 * (768/6144) = 81.25

So the pixel position of the top left hand corner of the rectangle is at position (62, 50) and will have with a width of 899px and a height of 81px.

 

 

ATC Agent Signatures

Air traffic control agents have signatures made up of four entries, for example:

AgentTracking=2,4,20287488,GREENLAKE

These four entries are made up of the following:

• The first number is always 2
• The second is the agent type (see the table below)
• The third number is a coding of the frequency
• The fourth entry is the call-sign.

In the example given above, the frequency coding is 20287477. To get this value we have taken the COM frequency of 135.9, multiplied it by 1000 to get 1359000. This value is considered as a hexadecimal and converted to decimal, which gives us 20287477.

 

The table below shows the values for agent type and what they correspond to:

 

Value	Agent Type
1	ATIS
2	ClearanceDelivery
3	Ground
4	Tower
5	Center
6	Approach
7	Departure
8	FSS
9	CTAF
10	ASOS

 

 

Waypoint Format

Waypoints in flight files consist of the following properties, separated by commas. The commas must be present even if there is no value.

 

Property	Description
region	The region code, such as K1.
ident	The ICAO ident.
airport	The name of the airport, which is not often used.
name ID	The name ID, often the same as ident.
type	One of: A : airport I : intersection V : VOR N : NDB U : user T : ATC
latitude	The latitude.
longitude	The longitude.
altitude	The altitude in feet.
airway ID	The airway ID, such as J5.
