German term or phrase: Bahnversatz
Hi everyone,

the term is from a document outlining the proposal for the extension of Berlin airport. This is a practice piece for Uni. The full document can be found here: https://lbv.brandenburg.de/3123.htm

• Anlage einer neuen, 1.900 Meter südlich davon gelegenen SLB (künftig südliche SLB 07R/25L) mit einer Länge von 4.000 Metern und einem Bahnversatz zur nördlichen SLB von 1.250 Metern;

At the moment I am thinking along the lines of :
…. off-set lane to the northern runway of 1250m.

Or is this the term for a taxiway or blast pad?

lateral spacing [offset] [separation]
Explanation:
This is the actual distance between the two runways....

"In summary,

"For simultaneous landings and takeoffs using VFR, the minimum separation between centerlines of parallel runways is 700 feet (213 m)."
For simultaneous IFR operations, "Dual simultaneous precision instrument approaches are normally approved on parallel runway centerline separation of 4,300 feet (1311 m). On a case-by-case basis, the FAA will consider proposals utilizing separations down to a minimum of 3,000 feet (914 m) where a 4,300 foot (1311 m) separation is impractical. This reduction of separation requires special high update radar, monitoring equipment, etc." Note: Simultaneous Offset Instrument Approaches allow as little as 750 ft between runway centerlines."

...adapting your own example, Yana...
"...and a lateral offset to the northern runway of 1250m..."

A better solution than using the word "runway" three times in one single sentence... :)

The Obstacle Free Zone (OFZ) for a precision instrument runway is considered as an alternate criterion to develop runway-taxiway separation. The offset, shown in figure 2-6, is an imaginary surface, 400 feet wide, at the elevation of the runway, which slopes upward and outward beyond 400 fee at a 3:1 slope. The minimum runway-taxiway separation which allows a B-767 to taxi on the proposed parallel taxiway without this tail (53 feet high) or its wing (span = 156 feet) penetrating the OFZ was calculated a 359 feet. A 359 foot offset option with proportionally less impacts than the 400 foot offsetwas therefore considered.
Although a final approval of this waiver of taxiway offset has not been granted, the preliminary response from the FAA indicates that this is a viable alternative. There is concern, however, that pursuing this waiver and construing the taxiway with a 359 foot offset may preclude the future installation of a Category II (DAT II) ILS approach system on Runway 11.

Taxiway addition - Associated with the extension of both runway 3nd 8 and runway end 13 is the modification of the adjacent parallel taxiway. Towards providing future Category ll capability a new parallel taxiway offset 600 ft. is planned for runway 8-26. The western segment, 3600 ft. in length, should be constructed when the runway end 8 is extended.

For instance, the runway-taxiway offsetof 275 feet in the extension of Taxiway 'B, ' which will require of modification of standards from FAA, was adopted specifically to reduce impacts to wetlands located east of the taxiway.

Sorry, auf den falschen Zug aufgesprungen!
Wenn ich mir das PDF ansehe, geht es beim Bahnversatz wohl eher um den Versatz der SLBs zueinander in 'Runway direction'. Der Abstand der RWY centerlines ist ja bereits mit 1900 m angegeben. Dann wohl eher etwas wie with southern RWY located 1250 m more to the southwest...

agree  Kartik Isaac: Yes sir!
2 hrs
  -> Sorry, I was wrong. Now I have corrected my answer to "staggered (runway) threshold".

agree  Björn Vrooman: Just staggered (threshold=Schwelle). Ex.: http://stopstanstedexpansion.com/planning_maps.html You need to specify a direction (e.g. west), as SLOPs are perpendicular(!). [Link didn't work]. Cf. LD in FAA document 6750.16E, pp. 15 + 22. It's longitudinal.
