confirm only a control to turn something off Explanation: You say "I know what ‘’confirm off’’ means,..." but I wonder if you really do? If you did, then this shouldn't puzzle you so much. In the options given, you have: no confirmation, = don't give confirmation for any controls confirm off control, = give confirmation for 'off' controls only (the more safety-critical ones!) confirm all controls = give confirmation for all controls (e.g. both 'off' and 'on' controls) Hope that answers your question? -------------------------------------------------- Note added at 2 jours8 heures (2015-01-22 07:45:36 GMT) -------------------------------------------------- I am assuming we are talking about controls to turn airfield lights on and off. Clearly, if the lights are left on by mistake, this will not matter very much, other than in terms of the power consumption! However, leaving the lights off when a plane is coming in to land could obviously be a much more serious matter — hence why I believe this would be important, and the relevance of this option. |
