<pre> In case of some planes with three-stage light switches (e.g. NAV and NAV+Strobe) it is possible that the logger will catch a state when the switch is in the middle position, but the pilot is merely switching it over. In such a case, the state of the light is logged immediately, which can cause some disturbances for PIREP reviewers. Therefore the logging of light statuses should be delayed to filter out such short-term changes. </pre>
