A launch operator must document a system safety process that identifies the hazards and assesses the risks to public health and safety and the safety of property related to computing systems and software.

A launch operator must identify all safety-critical functions associated with its computing systems and software. Safety-critical computing system and software functions must include the following:

Software used to control or monitor safety-critical systems.

Software that transmits safety-critical data, including time-critical data and data about hazardous conditions.

Software used for fault detection in safety-critical computer hardware or software.

Software that responds to the detection of a safety-critical fault.

Software used in a flight safety system.

Processor-interrupt software associated with previously designated safety-critical computer system functions.

Software that computes safety-critical data.

Software that accesses safety-critical data.

Software used for wind weighting.

A launch operator must conduct computing system and software hazard analyses for the integrated system.

A launch operator must develop and implement computing system and software validation and verification plans.

A launch operator must develop and implement software development plans, including descriptions of the following:

Coding standards used;

Configuration control;

Programmable logic controllers;

Policy on use of any commercial-off-the-shelf software; and

Policy on software reuse.
