inverselerp(0,"THRUST", -1 * ("MASS" * ((-1 * TAS * TAS ) / (2 * (AltitudeAgl - "HOVERZONE")) - 9.8)))  * clamp01(AltitudeAgl > "HOVERZONE" + "BUFFER") * clamp01(AltitudeAgl < "BURN START" )

Local CONSTANTS:
-THRUST: The maximum thrust of your engine. (Newtons)
-MASS: Mass of the craft. (KG)
-HOVERZONE: The equation will have the device perfectly stop at this point. (Meters)
-BUFFER: The system will cut out the engine landing sequence at this altitude, above the HOVERZONE. That way it lands and doesn't hover at 0m/s. (Meters above HOVERZONE, recc. 0.1)
-BURN START: The altitude AGL the craft will start its landing burn (The lower, the more thrust required to land safely)
