Time and motion
Tuc.
I thought that the time difference between the Trimble and Supertans was understood and thought to be insignificant........??????.......
..the gps unit has its own time clock , fed from the satellites and always set to UTC.( GMT/Z...).........whereas the RNS252 has a local clock which can be set manually by the crew to any time of choice . There is no provision to syncronize the two....If they chose not to fly a sortie on Zulu but use the local time, this difference could be plus or minus up to 12 hours in theory..............depending apon which theatre/part of the world they are operating in .........
..with regard to the on/off switch............similar locking toggle switches marketed today by Honywell or Eaton require that the toggle be pulled a mere 2.3 mm outwards ( about 3/32 inch ).... against a spring , in order to allow movement........not a great distance when there are significant G forces involved in decelerating from flying speed to zero in a short time...............if the unit stopped in about 8 feet for instance it is subjected to 100G , so if the toggle arm weighed 5grams normally it would behave as if it were weighing 1/2 kilo briefly......and if it were pointing in the direction of travel I think that would be enough to unlock the toggle...
