2.2.1 As a supplement to the approved stability
booklet, a computer may be used to facilitate the stability calculations
mentioned in 2.1.3.9.
2.2.2 The computer hardware and software should
be approved for stability calculation by the Administration. The input/output
format should, as far as practicable, be easily comparable in information
and format to the stability booklet so that the operators will easily
gain familiarity with the stability calculations.

manual written in the same language as the stability booklet, complying
with the provisions of 2.1.1, should be
provided.
2.2.4 In order to validate the proper functioning
of the computer hardware and software, pre-defined standard loading
conditions should be run in the computer periodically, at intervals
recommended by the suppliers but at least at every annual load line
inspection, and the printout should be maintained on board as check
conditions for future reference.
