Why Non Standard Extensions?
EuroScope needs to publish more information than possible in the current FSD version. Therefore some of them are published using standard elements but in a special way. We tried the best to define an extension in a way that the other controller who are not using EuroScope could use this information, but it will work the best only if both parties are using EuroScope.
Scratch Pad Strings
One of the most significantly used element is the scratch pad message. In ASRC and VRC this area is just a place for some short comments, but nothing more. In EuroScope some special formatted scratch pad strings are used to communicate additional information:
- VOR, NDB, FIX name – When a point name like VOR, NDB or FIX is entered to the scratch pad it is compiled as a direct to point assignment. The next route of the plane is updated accordingly. If you set a direct point using the popup menu in the COPX tag item, the name of the point is also published via the scratch pad.
- HXXX – Scratch pad string formatted as H* followed by numbers is interpreted as if heading were assigned to the plane. When you assign the heading using the popup menu then the appropriate HXXX format scratch pad message is published. If you need a heading assignment that is not available via the popup menu, you can enter it manually to the scratch pad (eg.
H022). To avoid the real scratch pad data to be deleted, the original content is sent just after the heading data.
- RXXXX – An R followed by numbers are interpreted as assigned climb/descend rating.
- SXXX – An S followed by numbers are interpreted as assigned speed in knots.
- MXXX – An M followed by numbers are interpreted as assigned speed in Mach number. Actually the value is used as Mach number multiplied by 100.
M75is used for Mach .75.
- CLEA – Special scratch pad content to indicate clearance received flag.
- NOTC – Special scratch pad content to indicate clearance not received flag.
- ST-UP – Special scratch pad content to indicate statup approved ground status.
- PUSH – Special scratch pad content to indicate push back approved ground status.
- TAXI – Special scratch pad content to indicate taxiing ground status.
- DEPA – Special scratch pad content to indicate departure (take off) clearance.
- HOLD – Part of the Holding List Plugin; Special scratch pad content to be issued after a DCT to indicate a hold over the DCT fix.
Special values in the temporary altitude assignment:
- 1 – If the temporary altitude is set to 1, EuroScope indicates that the plane is cleared for an ILS approach.
- 2 – If the temporary altitude is set to 2, EuroScope indicates that the plane is cleared for a visual approach.
Flight Plan Route Section
The flight plan route section is free text are. It is not easy to interpret the content in all cases, but allows additional information to be stored. The so called “standard” route elements like point names, airway names, EuroScope interprets the following items:
- SID/STAR name – The name of the SID or STAR (with or without ”’+” sign) is interpreted as SID or STAR and if found in the sectorfile extension then the points are added to the route.
- SID/<RWY name> or STAR/<RWY name> – If the SID or the STAR is followed by a slash then a RWY designator then it is interpreted as the plane will depart/land on the specified runway and will follow the specified SID/STAR. This format is important when the same SID/STAR name is used for different runways. This selects the right SID/STAR from the extension file. When you assign a SID/STAR using a popup menu from the new aircraft lists EuroScope will amend the flight plan adding this format to the beginning or to the end of the route section. Assigned SID/STAR and RWY data can be shown in the aircraft lists or even in the TAG.
- BADOV3D/31R – It indicates a ”’BADOV3D”’ departure from RWY 31R
- VEBOS3R/31L – It indicates a ”’VEBOS3R”’ transition to RWY 31L
- AIRPORT/<RWY name> – If the route section start with the departure airport name followed by a slash then a RWY designator then it is interpreted as departure RWY is assigned. Same if the destination airport is at the end followed by the slash and the RWY. It is interpreted as RWY is assigned for arrival. If an aircraft has an assigned RWY only the SIDs/STARs of this RWY will be used in the popup menu and in the route extraction.
- POINT/M085F320 (and M085F320/POINT) is accepted. The F320 is compiled as the requested level from the next point. This value is used for the profile calculation and also used as the RFL (if no controller overrides it).
Flight plan remarks section
- EOBT=HHMM – If the remarks section contains the following format string, then HHMM will be compiled as Expected Off Block Time for ground operations.
- START=HHMM – Similarly to the above it sets HHMM as the expecte engine startup time.
