The CG was usually expressed as 'mm ht MVH', with 'ht MVH' almost certainly short for 'hinter Mitte Vorderholm' or 'behind the center of the front spar'. This point is very likely, but not confirmed explicitly so far, 'Spant 4' (frame/bulkhead 4) at fuselage station 1800 mm. Refer to the Reference data for Me 163B CAD model for more information on the frame positions.
To express the CG as a percentage, the 'mean aerodynamic chord' (MAC) and its location of its leading edge (LEMAC) are required. In a drawing titled 'Flügel - Geheim' dated 14 January 1944 from the NASM archive these numbers are shown to be 1974 mm, and 126 mm behind Spant 4 respectively. This allows the calculation: taking '470 mm ht MVH' as an example, subtracting 126 mm gives the position on the MAC, 344 mm, and dividing that number by the MAC length gives the percentage, 17.43%.
Known CG positions are reported in the table below. Normal CG range appears to be 3.55%, but 5-7% is also reported. The CG positions reported by the RAE are rather different than those reported by German sources.
