The Project Apollo scenarios have a vast number of options that you can specify. Some of the more useful are:

General options

These are options specifying things such as the CSM and LM call signs, various masses, fuel masses and other parameters.

Option Function
TCP Specifies the height of the rocket above the ground in meters prior to launch. This can be adjusted if the mission is flown from a different launch pad to the default for the spacecraft (e.g. the Skylab 'milk stool' for the Saturn 1b).
APOLLONO Apollo mission number. This is used to provide mission-specific events such as mission audio or system failures.
VECHNO The Saturn vehicle number: typically this will be in the 200s for a Saturn 1b, and 500s for a Saturn V. This is used to name the separated stages and components of the spacecraft.
REALISM Sets the realism level from 0 (lowest) to 10 (highest). Lower realism level missions will be easier to fly. Quickstart mode is level 0, Virtual AGC mode is level 5.
DLS Set to 1 to delete the launch site when the spacecraft passes out of visible range. This can give a significant performance boost on slow machines.
FDAIDISABLED Set to 1 to disable the OpenGL FDAI rendering. This can give a significant performance boost on slow machines.
MISSNTIME Current mission time in seconds since launch.
IGMST Inertial Guidance Mode start: set to the time in seconds after launch at which the autopilot switches to inertial guidance mode and starts trying to hit the target orbit rather than follow the pre-planned pitch program.
SIFUELMASS

Specifies the mass in kilograms of the fuel in the first stage (S-IC or S-IB).

SIEMPTYMASS

Specifies the empty mass in kilograms of the first stage (S-IC or S-IB).

SICSHUT

Specifies the mission time of center engine shutdown of the first stage (S-IC or S-IB).

SISHUT

Specifies the mission time of shutdown of the remaining engines of the first stage (S-IC or S-IB).

SIIFUELMASS

Specifies the mass in kilograms of the fuel in the second stage (S-IVB for Saturn 1B or S-II for Saturn V). This is not used for the INT-20.

SIIEMPTYMASS

Specifies the empty mass in kilograms of the second stage (S-IVB for Saturn 1B or S-II for Saturn V). This is not used for the INT-20.

SIICSHUT

Specifies the mission time of the center engine shutdown of the S-II stage of Saturn V and derivatives.

SIIPUT

Specifies the mission time of the PU-shift (change of mixture ratio) the second stage (S-IVB for Saturn 1B or S-II for Saturn V).

SIISHUT

Specifies the mission time of shutdown of the remaining engines of the S-II stage of Saturn V and derivatives.

S4FUELMASS

Specifies the mass in kilograms of the fuel in the S-IVB stage of Saturn V and derivatives.

LMASCFUEL

Specifies the mass in kilograms of the fuel in the LEM ascent stage, if appropriate.

LMDSCFUEL

Specifies the mass in kilograms of the fuel in the LEM descent stage, if appropriate.

SMMASS Empty mass of the Service Module, in kilograms.
CMMASS Empty mass of the Command Module, in kilograms.
S4PL

Specifies the payload of the SIVb stage. Current values are:

0 Standard LEM
1 ASTP
2 LTA LEM test article
3 LM1 test LEM
4 LTA8 LEM test article
5 Docking target
6 LTA6 LEM test article
7 Empty
8 Docking adapter for an SIVb 'wet workshop'

AUTOSLOW Set to 1 to slow to 1x time acceleration when 'something important' happens. For manned flights, this is typically when a piece of mission audio is played, for unmanned flights it is typically a stage separation, engine burn, etc.
LANDFAIL Landing failures. Set to 1 to disable all random landing failures in your scenario, or 0 to create a random set of failures.
LAUNCHFAIL Launch failures. Set to 1 to disable all random launch failures in your scenario, or 0 to create a random set of failures.
SWITCHFAIL Switch failures. Set to 1 to disable all random switch failures in your scenario, or 0 to create a random set of failures.
UNMANNED Set to 1 for an unmanned mission.
ATTACHSTATE Specifies which 'things' are attached to the spacecraft. This is a bit-field, created by combining the following values as appropriate.

1 The interstage is attached.
2 The LES is attached.
4 There is a docking probe.
8 The Apex Cover is attached.
16 The parachutes are attached.
32 There is a CSM on the launcher.
64 If there is no CSM, there is a nosecap on the SLA panels.

Defaults are generally safe to use, but you may need to specify the value in the scenario for unusual missions (e.g. Apollo 5 with no LES or CSM and a nosecap uses 93).

HASPROBE Allows you to override the default docking probe state. Set to 1 if the spacecraft has a docking probe, or 0 if it doesn't.

This value is not saved in scenarios written out by orbiter, it is purely intended to allow you to set the docking probe state in initial scenarios without having to specify the full value for ATTACHSTATE. If you specify both HASPROBE and ATTACHSTATE in the same scenario, then whichever value comes second will be used for the docking probe state.

SLASTATE Specifies the state of the SLA panels on the SIVB. Bit 8 should be set to 1 if the panels are hinged, or 0 if they separate from the SIVB. Bits 0-7 specify the angle to which they will open if hinged, defaulting to 45 degrees with an upper limit of 150 degrees; if they're not hinged, they currently always separate at 45 degrees.

In most cases the default will work fine (hinged to 45 degrees on Saturn 1b, not hinged on Saturn V), but special missions may require manually setting this state. For example for hinged panels opening to 150 degrees use "SLASTATE 150" in the scenario.

PAYN Sets the payload vessel name (e.g. Eagle for the Apollo 11 LEM). This is the name the SIVB payload will be given when it is created; LEMN can be used as a synonym.

Mission parameter options

These are options specifying things such as the earth parking orbit parameters, lunar landing site, various mission time parameters etc.

Option Function
TOAPO Specifies the desired launch apogee altitude in kilometers.
TOPER Specifies the desired launch perigee altitude in kilometers.
TOHDG Specifies the desired launch azimuth in degrees.
TLIMJD Specifies the desired MJD of the TLI burn.I
LOIMJD Specifies the desired MJD of the first LOI burn.I
FREERETURNPECMJD Specifies the desired MJD of the free return pericynthion.I (currently unused)
FREERETURNPECALT Specifies the desired altitude (in meters) of the free return pericynthion.I (currently unused)
TLIOFFSETLON Specifies the longitude of desired target offset (in radian) of the TLI burn.I
TLIOFFSETLAT Specifies the latitude of desired target offset (in radian) of the TLI burn.I
TLIOFFSETRAD Specifies the radius of the desired target offset (in meters) of the TLI burn.I
MOONMJD Specifies the desired MJD of the lunar landing.I
MOONBASE Orbiter base name of the planned landing site on the Moon, if any.I
MOONLAT Latitude (in degrees) of the planned landing point on the Moon, if any.
MOONLONG Longitude (in degrees) of the planned landing point on the Moon, if any.
MOONALT Altitude (in meters) of the planned landing point on the Moon, if any.
EARTHEIMJD Specifies the desired MJD of the Earth landing entry interface, if any.I
SPLASHLAT Latitude (in degrees) of the planned splashdown site on the Earth, if any.I
SPLASHLONG Longitude (in degrees) of the planned splashdown site on the Earth, if any.I

Audio options

Option Function
LANG Set to the appropriate string for the audio language you want to use. Currently we only ship English audio, but if, say, you downloaded a French audio add-on you could set this to French instead and the French files would take precedence.

AGC options

AGC options are specified between AGC_BEGIN and AGC_END. Options outside those lines will be ignored.

Option Function
YAAGC Set to 1 to use the Virtual AGC rather than the C++ AGC
EMEM Set an AGC erasable memory location to a specified value. Addresses and values are both specified in octal (base-8), so to set address 10 (decimal) to 17 (decimal) you would specify EMEM0012 21. In general you should use LMPAD and CMPAD instead of specifying specific memory locations as both C++ AGC and Virtual AGC use the same scenario values to store different data.

Virtual AGC options

These options are set in the standard CSM configuration, not between the AGC_BEGIN and AGC_END lines. If you try to set them inside the AGC configuration they will be ignored.

Option Function
CMPAD Set a Virtual AGC erasable memory location in the CM AGC to a specified value. Addresses and values are both specified in octal (base-8), so to set address 10 (decimal) to 17 (decimal) you would specify EMEM0012 21. If the scenario uses the C++ AGC rather than Virtual AGC, these values are ignored.

CMPAD entries are used once to set up the values in the AGC when the scenario is loaded, then thrown away. So they will not be saved to a scenario file when you exit Orbiter.

LMPAD Set a Virtual AGC erasable memory location in the LM AGC to a specified value. Addresses and values are both specified in octal (base-8), so to set address 10 (decimal) to 17 (decimal) you would specify EMEM0012 21. If the scenario uses the C++ AGC rather than Virtual AGC, these values are ignored.

Note that the LEM PAD is loaded when the LEM is created, so setting these values when the LEM already exists in the scenario will have no effect.

LMPADCNT Sets the number of LEM PAD entries. The LEM PAD is saved in a table until the LEM is created, so the DLL needs to know how large a table to create. Any values beyond this count will be ignored.

Checklist Information

These values are defined between the lines <checklist> and </checklist>

Option Function
FILE This is the file name of the checklist file to use.
AUTO This defines whether to automatically execute the checklists.

Additionally there are two items to define in the launch vehicle before the scenario starts. These are NOT defined between <checklist> and </checklist>

Option Function
LEMCHECK This is the file name of the checklist the LEM should use.
LEMCHECKAUTO This defines whether the LEM should automatically execute the checklists.

Scenario information

These values aren't typically set in a newly created scenario, but are saved to the scenario from the DLL when exiting Orbiter.

Option Function
NASSPVER This gives the version number of the DLL which saved the scenario... for 7.0 it's 70000.
