• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

I know this is a HUGE thing to ask, but i've been looking throughout the forum and can only find information about one or two different types of Runway Lighting and Markings.

It would be GREAT to me [And the rest of the community im sure] if someone could describe what each selection means, just so it is easier to decide what will be best for certain airports.
Ill type a list of the different selections so its easier for you. [You can just copy and paste to save a little bit of time on typing].

APPROACH LIGHTS
[Dropdown]
- ODALS
- MALSF
- MALSR
- SSALF
- SSALR
- ALSF1
- ALSF2
- RAIL
- CALVERT
- CALVERT2
- MALS
- SALS
- SSALS
[Tick Box]
- End Lights
- REIL
- Touchdown

- Strobes

VASI LIGHTS
- VASI21
- VASI31
- VASI22
- VASI32
- VASI23
- VASI33
- PAPI2
- PAPI4
- TRICOLOR
- PVASI
- TVASI
- BALL
- APAP

MARKINGS
- Alternate Threshold
- Alternate Touchdown
- Alternate Fixed Distance
- Alternate Precision
- Leading 0 Indent - Displays a 0 infront of runway number.
- No Threshold End Arrows
- Edge Lines - Lines at edge of runway.
- Threshold Stripes - Stripes at the threshold.
- Fixed Distance
- Touchdown
- Centre Line - Line down centre of runway.
- Ident - Runway Number
- Precision
- Edge Pavement
- Single End
- Primary Closed - Cross at primary end.
- Secondary Closed - Cross at secondary end.
- Primary STOL
- Secondary STOL

Thank you in advance to anyone who replys.
Ill update the post when some are explained!
 
ODALS - Omnidirectional Approach Light System.
The ODALS provides runway end identifier lights and
useful circling, offset, and straight-in visual guidance for
nonprecision instrument approach runways.

MALS
Medium intensity approach lighting system (MALS).
This system may be used where a precision approach is not
available or justified. The runway lighting system will be of
the medium intensity type. The approach lighting system
will consist of light bars spaced on 200-foot centers extending
outward 1,400 feet from the threshold. Where
authorized, condenser discharge lights may be installed in
the outer three bars. When the condenser discharge lights are
used, this system will be indicated as MALSF.

MALSF - Medium Intensity Approach Lighting
System with Sequenced Flashers. Same as MALS but
equipped with three sequenced flashers collocated with the
outer three light bars of the system. This system is used at
locations where approach area identification problems exist.

MALSR - Medium Intensity Approach Lighting
System with Runway Alignment Indicator Lights (RAIL).
An economy type system used for precision instrument
approaches of a Category I Configuration (an ILS approach
procedure which provides for approach to a decision height
of not less than 200 feet).

ALSF-2 - High Intensity Approach Lighting
System with Sequenced Flashers. Standard system for
precision instrument approaches of a Category II
Configuration (an ILS approach procedure which provides
for approach to a decision height of not less than 100 feet).

Runway end identifier lights (REIL). The primary
function of the REIL is to provide rapid and positive
identification of the approach end of a runway. The system
consists of two sychronized flashing lights, one on each side
of the runway landing threshold, facing the approach area.
The flashing feature of the lights provides an eye attracting
characteristic, making the REIL effective for identification
of a runway surrounded by a preponderance of other lighting
or lacking contrast with surrounding terrain.

Maybe this is something that can be put in the next version of the programm manual? :)

Well we are looking at the whole subject of documentation for ADE in the future so we will certainly bear that in mind :)
 
Until ADE gets it all added you could open Lee Swordy's AFCAD2 documentation. Everything is in there including pictures.
 
I want to build a Rwy with SALS approach lightings.

360m at rwy 06 and 420m at rwy 24

Is there a way to change SALS lenght?

Vasi22 Biasz

Hi In stock airports A runway of 10097 ft has Biasz 3648,
a Runway of 5303 biasz of 1501, what Determinesbiasz ?
If I create a runway of say 7000 ft Is Biasz About 2500?
thanks terrawatt
 
The BiasZ is for the VASI.
Let us see your examples.

Example One:
A runway of 10097 ft
And now from the middle of the Runway you go 3648 ft left or right and at this place sit the VASI, similar to the other side.

Example two:

A Runway of 5303 feet and now from the middle you go 1501 ft and there sit the VASI.

The VASI are sit on most time left or right of the TouchDown Zone. In ADE you will see a red Sign at the location of the BiasZ.
Change the BiasZ in the Runway Properties und the Primary or Secondary Section and you see how the red sign will move, every time you change the BiasZ.

The BiasX is the Horizontal Location in feet from the Centerline of the Runway.

Cool :)

The next version of ADE has a night mode so that approach and runway lighting will be displayed in ADE.

My understanding is that the PAPI is typically located about 300 meters or so beyond the landing threshold of the runway.

In your two examples and without further knowledge of whether the runways contained a displaced threshold, it would appear that the PAPIs were place between 305-350 meters beyond the threshold. If the runway contains a displaced threshold, and as this is included in the total runway length, this would need to be factored in.

If you were to create a runway 7000 feet in length (no displaced threshold) and based on the general information for PAPI placement, a Biasz of 2500 feet is a good first estimate of the PAPI location, which would place it around 305 m from the runway threshold. Always a good idea to take a look at the placement in-game to see if it makes sense.

I'm sure others have a more precise method of calculating the location but your estimate seems reasonable to me.
