Up and down are self explaining. The "off" position removes all hydraulic power to the gear system. The "off" position is used in flight where we have no need for hydraulic power as the gear is held up by mechanical up locks. The "off" position is used no less than 10 seconds after up has been selected.......in the real world that is.

1. Captain, if the problem is not entered into the technical logbook.........then the aircraft does not have a problem.
2. And, if you have time to write the fault on a napkin and attach to it to the yoke.........you have time to write it in the tech log....see point 1.
