FG SimBrief Importer Add-On
|
|
===========================
|
|
|
|
What Is This?
|
|
-------------
|
|
|
|
This is an add-on for FlightGear that adds a SimBrief Import dialog.
|
|
|
|
(See https://www.simbrief.com/).
|
|
|
|
What It Does
|
|
------------
|
|
|
|
The SimBrief importer can import various aspects of a SimBrief flight plan into
|
|
FlightGear. The import functionality attempts to support as many aircraft types
|
|
as possible, but due to the nature of the beast, it does not work equally well
|
|
with all of them.
|
|
|
|
Ideally, the following functionality will be supported:
|
|
|
|
- Flight Plan Route: This one imports the departure and destination airports,
|
|
and all enroute waypoints, into the default flightplan. If "Activate
|
|
immediately" is checked, it will also activate the flightplan.
|
|
- Departure RWY, SID: This will attempt to select the planned departure runway,
|
|
and the planned SID, from the flightplan. Note that this will only work if
|
|
your FlightGear navdata matches the selections from SimBrief, which may not
|
|
be the case, especially if you're using the default FG navdata and/or an
|
|
outdated AIRAC cycle in SimBrief. SID selection will also fail if SimBrief
|
|
uses a different naming convention than FG's navdata.
|
|
- Arrival RWY, STAR: This will attempt to select the planned arrival runway and
|
|
STAR. The same caveats apply as with the departure runway and SID.
|
|
- Performance Init: This sets a handful of key performance parameters;
|
|
currently: cruise altitude and callsign.
|
|
- Payload: Imports passenger and cargo weights, and attempts to distribute them
|
|
sensibly over available payload weight slots.
|
|
- Fuel: Imports block fuel as per the flightplan, and attempts to distribute it
|
|
sensibly over available fuel tanks. Two fuel allocation strategies are
|
|
provided:
|
|
- "Balanced": distributes required fuel proportionally over all tanks,
|
|
according to their declared capacities - large tanks get more fuel, small
|
|
tanks get less fuel.
|
|
- "First come, first serve": distributes fuel by filling tanks in declaration
|
|
order. Some crude heuristic is in place that attempts to detect left/right
|
|
pairs of wing tanks from their names, to keep things balanced, but it is
|
|
not foolproof.
|
|
Which of these strategies is more suitable depends on the aircraft type. If
|
|
neither is good enough, but the aircraft comes with a "balance fuel" button,
|
|
the recommended way is to use either fuel strategy, and then simply press
|
|
the "balance fuel" button to let the aircraft sort it out.
|
|
- Winds Aloft: Runs a background process that sets winds aloft according to the
|
|
forecast winds in the flightplan. This will only work with Basic Weather,
|
|
since the Advanced Weather engine runs its own wind simulation that will
|
|
overwrite winds aloft regardless of what we set.

|
|
|
[1] - This aircraft already includes a SimBrief import feature, so this addon
|
|
will either not work or disable itself. Please use the aircraft's
|
|
built-in SimBrief importer instead.
|
|
[2] - Imports cargo, but not passengers, due to nonstandard handling of
|
|
passenger counts.
|
|
[3] - Nonstandard handling of cargo and passengers.
|
|
[4] - Imported flight plan is of limited use, because the aircraft does not
|
|
have an FMS.
|
|
[5] - Currently works, but devs plan to make a custom importer, at which point
|
|
[1] will apply.
|
|
|
|
Aircraft types not on this list may or may not work; they simply haven't been
|
|
tested. Contributions on this front are very welcome.
