The LAS has since version 5.0 a fundamental new expansible airspace data structure.
There is no limitation to 48 VOR/ILS and 36 NDB frequencies any more.
The number of the data types and so same of the NAVs is as you like.
Also the number of the data of a data type is expansible, so that
extra parameters can be added if required.
Geographic world coordinates (WGS 84)
All coordinates were changed from local coordinates to geographic world coordinates (WGS-84).
All navigational calculations of the LAS are now on a sphere
(spherical trigonometry). That is the reason that there is no marginal distortion of
lenght at the borders of the airspaces any more for the so far used
Mercator projection. The airspace data of all airspaces are merged at the program start;
there is no longer a airspace selection in the the master menu.
Therefore flights are possible across airspace boundaries without any break.
Easily editable
The new airspace structure can easily be edited or extended with Word, Notepad or DOS-Editor.
Because of this faster updates will be possible in the future.
The datas can be edited even by the user himself.
New data types
Because of the new airspace data structure complete new data types are possible.
The following types are already realized:
Intersections: displayed now in the Mapping, if used (Direct Navigation or Route Navigation).
stand-alone Marker: indepentent from reception of an ILS
(by the way with lens shaped reception characteristic)
Runways: with the individual, published minima (DA/MDA).
No standardized minima 200 ft (DA) and 400 ft (MDA) any more.
Automatic runway- and approach type finding became possible.
stand-alone DMEs
New since version 5.1: TER (Terrain) Terrain can be programmend by height
point and slope, what makes approaches more realistic, especially at airfields in the
mountains.
New since version 6.0: WPT (Waypoint), RTE (Route), LEG (Leg-Definition),
FOW (Fly-over-Wpt.), FAF (Final Approach Fix), MAP (Missed approach waypoint)
These new data types became necessary, because of the introduction of the new GPS.
Additional type are possible, as e.g. airways, obstacles an so on.
New parameter
The previous data types were extented by numerous new parameters.
Range: because of this it was possible to program, that the reception
depends on range and height. This is also the reason, that now beacons
with the same frequency are possible, for their range don't overlap themselves
under normal circumstances. You only receive that one, which is within its
range. In addition the reception of an ILS is now limited to 25 NM (ICAO)
and 18 NM (USA) respectively to centerline ±10° and to 17 NM (ICAO)
and 10 NM (USA) respectively to centerline ±35°.
Label (position of the indicator in the mapping) enables the
disentanglement of the labels in the mapping
ATIS/Voice enables to listen ATIS on a VOR frequency, resp.
voice identification ("This is Frankfurt ILS runway 25 right")
Improved radiotelephony simulation
The new airspace data structure enables a essential improvement of the
radiotelephony simulation on original radiotelephony frequencies.
The data type COM was extented by the parameters range, name, service
(tower, ground, departure an so on) and radar destination. The tower frequencies are
not longer used for determination of departure (or in the air: of destination).
That's why they became free for take off and landing clearances.
You get ATIS now on the published ATIS frequencies. Detailed
taxi clearances on ground frequency will guide the pilot to the holding position.
Radar vectoring now only to airports with published SRE approach.
