New page

'''NASSP''' simulates various failures for the CSM, LM and Saturn rockets. To enable them select "Damage and Failure Simulation" under Realism in the Parameters tab of the Orbiter launchpad. Failures can be scheduled or randomized. Aside from specific failures in the simulation, generic switch failures are supported where systems see the state of a switch in a failed switch position, different from the actual position. The specific failures can be scheduled or randomized in the Project Apollo MFD, switch failures are currently only available through editing scenarios.

=Specific Failures=

For failures to occur they have to be "armed" and a failure condition has to be added to them. These conditions are currently all time based. For both CSM and LM the mission time since launch (failure condition 0) can be used as well as the simulation time (failure condition 1) since the start of the simulation. Only the CSM currently supports more failure conditions.

==CSM Failures==

The list of available failures that are simulation can be viewed directly in the PAMFD page for failures. The majority of them are still launch or reentry related.

The additional failure conditions for the CSM are:

*2 = time since S-I/S-II (or S-IVB) staging
*3 = time since S-II/S-IVB staging
*4 = time since Earth Orbit Insertion
*5 = time since TLI preparations start (Timebase 6)
*6 = time since TLI cutoff

==LM Failures==

No specific failures are currently supported for the LM, but switch failures can be scheduled on mission or simulation time.

=Switch Failures=

Switch malfunctions have to be added to scenarios. For this, a failure section in the scenario has to be added that starts with line FAILURES_BEGIN and ends with FAILURES_END. In between, the following format is used.

SWITCHMALFUNCTION GNComputerMnACircuitBraker 0 0 100.0

1st parameter: name of failed panel element
2nd parameter: failure state of panel element
3rd parameter: The condition type for the failure. See above.
4th parameter: The time value associated with the condition type.

There is no list of switches, but the names can be derived from the saturnpanel.cpp and lempanel.com files where the names are used in the Register function for each switch.
