The Gnome differed from the T-58 in having a British developed fuel control system (Lucas).

Because an all-axial design is employed, the final stage compressor rotor blades are amongst the smallest ever manufactured.

The engine was the first developed with a full authority analogue computer, de Havilland Propellers' own, as part of the fuel control system, specifically to anticipate helicopter power demand from pilot control inputs and to limit fuel flow during acceleration to prevent engine surge from occurring.

[6] and in this way was the analogue forerunner of all subsequent full authority digital engine control (FADEC) systems worldwide.
