LCAS’ fully certified (Supplemental Type Certificate) Gravity meter interface is designed to give aircraft the ability to carry a CHECKAN gravity meter system in the cabin area. This installation is completed using LCAS interface plates to secure the gravimeter to the aircraft by attaching the interface plate assembly to the seat rails and providing restraint systems.

The modification can include supporting systems installations consisting of (but not limited to) SkyTrac and GPS antennas, AG-NAV display and radar altimeter system coupled to the data acquisition systems
