Flight Design CTLS weight & balance

Data source

AOI AF 043 00005, Section 2.4 (p. 2-2), Section 6.1-6.3 (pp. 6-1 to 6-8): Loading Diagram, Permissible Moment Range, Permissible CG Range (pages 15-66 of ctls-lsa__aoi__af04300005-rev8.pdf) · version type

• MTOM is 450-600 kg depending on national laws/certification; 600 kg (1320 lb) is the LSA value used in the charts. Check the value certified in your country.
• Minimum pilot weight: page 2-2 (Rev 8) says 54 kg (120 lb); section 6.1 (Rev 6) says 60 kg (120 lb). 54 kg used; verify.
• Maximum per seat: page 2-2 says 118 kg (260 lb); section 6.1 says 120 kg (260 lb). 118 kg used; verify.
• Baggage: 25 kg maximum on each side, 50 kg total. Footroom storage maximum is not explicitly printed; it is counted here in the 50 kg baggage group. Verify against the current weighing record, which may give lower values.
• Fuel capacity of 130 L (34.3 USG) is read from the Loading Diagram fuel axis. Usable fuel is not stated on these pages. Fuel density 0.725 kg/L (6.05 lb/USG) is as printed.
• The envelope is a rectangle: CG 0.282-0.478 m (11.1-18.8 in) up to 600 kg. The lower mass of 300 kg is only the chart's bottom edge, not a printed limit.
• The typical empty values are from the sample loading table: 318 kg and 107.1 kg*m, giving an arm of about 0.337 m. Page 2-2 gives a nominal empty weight of 310 kg (730 lb) without an arm. Always use the aircraft's own weighing record.
• Imperial equivalents printed: seats 20.5 in, aft luggage 45 in, footroom -13.2 in, fuel 8.3 in.
• Read from the POH by ZuluCheck and checked by a second reading; verify against your own manual.
