Slugs-specific navigation modes.

ValueField NameDescription
0SLUGS_MODE_NONENo change to SLUGS mode.
1SLUGS_MODE_LIFTOFFVehicle is in liftoff mode.
2SLUGS_MODE_PASSTHROUGHVehicle is in passthrough mode, being controlled by a pilot.
3SLUGS_MODE_WAYPOINTVehicle is in waypoint mode, navigating to waypoints.
4SLUGS_MODE_MID_LEVELVehicle is executing mid-level commands.
5SLUGS_MODE_RETURNINGVehicle is returning to the home location.
6SLUGS_MODE_LANDINGVehicle is landing.
7SLUGS_MODE_LOSTLost connection with vehicle.
8SLUGS_MODE_SELECTIVE_PASSTHROUGHVehicle is in selective passthrough mode, where selected surfaces are being manually controlled.
9SLUGS_MODE_ISRVehicle is in ISR mode, performing reconaissance at a point specified by ISR_LOCATION message.
10SLUGS_MODE_LINE_PATROLVehicle is patrolling along lines between waypoints.
11SLUGS_MODE_GROUNDEDVehicle is grounded or an error has occurred.


These flags encode the control surfaces for selective passthrough mode. If a bit is set then the pilot console has control of the surface, and if not then the autopilot has control of the surface.
