The following instructions are defineing different navigation radio systems. The data records generated by the following instructions are only used for the simulation system. For FS98 and later you also need to define these devices in the "airport facility data" section. See file sca_afd.htm for more information.

Files containing nav radios must start with:

to generate the BGL file header structure.

 

The commands:

 

FS5 - FS2002
VOR(FrqRng FlagsMagvarIDName
 LatLonElevHdg )
 

Defines an VOR. For details see ILS().


TOP 

FS5 - FS2002
ILS(FrqRng FlagsMagvar 
 IDName   
 LatLonElev Hdg; localizer
 LatLonElev Slope; GP
 )     
 

Defines an ILS (instrument landing system)

Frq  frequency in mc -> 113.45
freq. range VOR 108.0 ... 117.975 mc
freq. range ILS 108.0 ... 111.975 mc
Rng  range in 2048 meter units. This is somewhat larger than a mile (1nm = 1852m). Only integer values up to 255 are accepted. It seems FS5 can handle this, but the DME display will only show "99" as a maximum.
Flags  2 digit hex value
01  DME availabe bit
02  TACAN (set DME bit also!)
04  voice available (ID ? ATIS ?)
08  no NAV signal available
(-> 09 is DME without VOR)
10  DME at glideslope transmitter position bit
20  localiser back course not available
40  glideslope transmitter ON bit
80  localizer on ON bit
This bit is on for normal ILS, OFF for VOR and SDF (simplified directional facility)
example values:
00 or 02 -> VOR
01 or 03 -> VOR-DME, VORTAC
Magvar  magnetic variation (eg.-3.7). Only for VOR.
Normally 0 for ILS. If 0 the VOR/ILS is aligned with true north. To get a nav receiver readout which corresponds to your compass you should enter the magnetic variation. This gives the VOR the same error than your compass.
ID  ID string, up to 5 characters
Name  Name string, up to 24 characters. Use '_' in place of ' '.
Lat  latitude
Lon  longitude
Elev  elevation in meters (MSL, integer)
Hdg  heading (true) in degrees (ILS only, always 0 for VOR)
Slope  slope angle of GP transmitter -> 3.0
Note: There is a known problem with the slope in the southern hemisphere in FS5.0 and FS5.0a.
Remark: Not all ILS systems have an DME equipment. In the USA DME's usually show the localiser distance. In Europe DME's usually show the touch down zone (TDZ) distance (position of the GP antenna).

FS98 - FS2002
DMEPos( Frq flg Lat Lon elevation )
 

This command was first found in FS98.
This command is only needed if the position of the DME is not the same as the associated VOR or ILS-localiser.
This command must immediately follow the associated ILS()/ILS2() command and must have the same frequency as the ILS. Be sure that the asociated ILS has the "DME available" flag set.

Frq  The frequency of the ILS system
The frequency is not coded in the command but is needed for sorting purposes in all navaid objects.
flg  unknown - always found 1
Lat  Latitude
Lon  Longitude
elevation  elevation (integer, MSL) in meter

FS5 - FS2002
NDB( Freq Rng ID Name Lat Lon Elev )
 

This command defines an NDB (Non Directional Beacon).

Freq  frequency in kc, range 200.0 ... 526.
Rng  Range in 2048 meter units (integer)
(you can asume this as nm units)
ID  5 char NDB id string
Name  24 char Name string, if you want to include space characters use '_' instead.
Lat  latitude of the position
Lon  longitude of the position
Elev  elevation (MSL) in meters (integer)

FS5 - FS2002
IM( Lat Long Elev [o] )
MM( Lat Long Elev [o] )
OM( Lat Long Elev [o] )
 

Marker beacons:

IM  inner marker
MM  middle marker
OM  outer marker
Lat  Latitude
Lon  Longitude
Elev  elevation in meters (MSL, integer)
o  SCASM 2.41 and later
orientation (heading to the runway) in degrees. Precision abt. 1.4 degrees.
This value is used because the radiation diagram of a marker beacon is a flat ellipse oriented across approach course.
