percent (10%) of pilot positions will be preserved for pilots electing protected rights status (a "rights status position") at Compass Airlines. In the event of a reduction in the total number of positions at Compass, the number of "preserved positions" and "rights status positions" will be adjusted to maintain the nine to one (9:1) ratio. "Rights status" will be removed from pilots in reverse seniority order and such pilot will again have flow rights to Northwest.
In order to have protected rights status one must be offered a flow up and then turn it down. There are no Compass pilots who fit into this category.
