Runtime settings
Commands of the runtime_settings chapter of the database, 12 entries. The status words are defined once, on the compatibility matrix, which says what each rests on and what the script builder does with it. Read it before this page: broken and removed are refusals, so a row here can be telling you the emitter will not write that command for that version.

Phase init, layout inline. Manual: SRC-003 p.339.
Side-slip angle; magnitude must stay below 90 degrees. Under SYMMETRY MIRROR the solver runs at zero sideslip whatever this command states and says so only in the log, whose side-slip line reads .000; measured on 26.120 on 2026-09-09 (pfs0130 row 4207, the export printing .000 for a stated -4.0); the package refuses a nonzero sideslip under MIRROR at plan time.
