German term

Bahnversatz

German to English Tech/Engineering Aerospace / Aviation / Space
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?

Discussion

Johannes Gleim Mar 22, 2020:
@ Yana As the discussion shows a lot of peers are puzzled about the choice taken. This is especially true as "lateral spacing [offset] [separation]" contains several options. Can you please tell us, which of these terms actually have been used? Thank you in advance.
Björn Vrooman Mar 21, 2020:
It's the same here. Lateral offset is for the width:
http://aixm.aero/sites/aixm.aero/files/imce/AIXM51HTML/AIXM/...

Heck, "Schwellenversatz" [staggered threshold] is even on Wikipedia:
https://de.wikipedia.org/wiki/Start-_und_Landebahn#Konfigura...

It has already been mistranslated in the following document on p. 8: https://www.bfu-web.de/EN/Publications/Investigation Report/...

This article is about Heathrow and shows the same kind of layout: "The new runway will be parallel to the existing runways but is staggered so that it lies further west."
https://www.pagerpower.com/news/heathrow-third-runway-safegu...

It's virtually the same in all similar documents:
"The stripes extend sideways to within 10 feet from the edge of the runway or to a distance of 90 feet on either side of a runway centerline, whichever is the smaller lateral distance."
http://wwwsp.dotd.la.gov/Inside_LaDOTD/Divisions/Multimodal/...

I could work with offset. Lateral is just wrong.

Best wishes
Björn Vrooman Mar 21, 2020:
Yes, Kim This is about right.

If the asker wants to use lateral, that's her choice.

This doesn't mean everyone else who might need to know what this is called has to get blindsided.

Here's a map of the airport:
https://de.wikipedia.org/wiki/Datei:Karte_Flughafen_Berlin_B...

It's similar to Munich's:
https://upload.wikimedia.org/wikipedia/commons/1/1c/Karte_vo...

Both have parallel runways. The Bahnversatz in Munich can be found here:
"Zwei parallele, 4000 Meter lange und 60 Meter breite Start- und Landebahnen im Abstand von 2300 Metern, Versatz der beiden Bahnen um 1500 Meter."
https://mucspotter.de/mucnews/daten.html

The Abstand(!) is the runway separation mentioned at stackexchange. And the "lateral distance" described on pp. 15 in the following FAA document is the exact opposite of what is meant in this context: https://www.faa.gov/documentLibrary/media/Order/FINAL_SIGNED...[1].pdf

The same is true for SLOP (Strategic Lateral Offset Procedure): that's when airplanes fly on a parallel track to the right.

Dictionary entries for Versatz.... offset -> check
lateral offset -> check
staggered -> completely MIA -> can anyone imagine why...?
Pleasant weekend!

Kim Metzger Mar 21, 2020:
Bernd - just google offset (stagger) runways https://www.reddit.com/r/airportceo/comments/7406a1/offset_s...
Chris Pr Mar 21, 2020:
The term in question still remains "Bahnversatz" and the belated idea of somehow shoehorning "threshold" into the equation really doesn't move anything further forward at all.
Bernd Runge Mar 21, 2020:
staggered (runway) threshold ... ist wohl die gängige Bezeichnung für sowas ... Zumindest bei der FAA.
Johannes Gleim Mar 21, 2020:
@ Rolf Ich habe den lbv-Link noch mal auf diese Aussage hin geprüft, konnte aber dazu nichts finden. Welche andere PDF ist gemeint? Abgesehen davon kann Versatz in allen Richtungen vorkommen. Das gleiche gilt für "offset", nicht aber für die übrigen Vorschläge.
Bernd Runge Mar 21, 2020:
Ich weiß nicht, ob meine Bemerkung zu meiner Antwort untergegangen ist: Es geht nicht um den (Quer-)Abstand zwischen den beiden SLBs, sondern darum, dass die 25L 1250 m 'später beginnt' als die 25R, also mit Versatz in missweisende Richtung 247°!!!
Johannes Gleim Mar 21, 2020:
Chris offered 3 terms to choose from: 'lateral spacing [offset] [separation]'. I proposed only one, found as described and confirmed by several references.

Kudoz has no rule to hide own findings. Contrary to this, peers are encouraged to submit it in the answer section and to add reliable references. And I adhere to the rules.
BTW, The discussion box serves for providing additional pieces of information to the subject, rather than to discuss answers or personal decisions to post or not to post.

lateral spacing [offset] [separation]

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... :)
Note from asker:
Thank you so much for your help Chris! Really appreciate it. Yana

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.

runway centerline spacing

... als Denkansatz ...
Die Meter müssten natürlich noch umgerechnet werden.

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...

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.
