Van's RV-12iS weight & balance

Data source

RV-12iS POH (VAD-10003) Section 6, 6.2 Operating Weights & Loading, 6.5 Sample Loading Problem, Figure 6-1 Flight Envelope - Arm, Figure 6-2 Flight Envelope - Moment; Section 7.3 (pages 78-87 of rv-12is__poh__vad-10003-r15-2026-07-16.pdf) · version type

• CG range 80.49 to 85.39 in (18.4 to 27% chord) at all weights up to 1320 lb, per 6.2 and Figure 6-1.
• The 800 lb bottom of the envelope is the chart's lower edge, not a printed limit; the manual states minimum weight varies with the aircraft's empty weight.
• Figure 6-2 (moment envelope) does not match the arm limits exactly (its lines converge near 845 lb and show a break near 1255 lb); the arm limits from 6.2/Figure 6-1 were used.
• Baggage 75 lb maximum (dependent on the CG limits).
• Fuel tank capacity and usable fuel are not printed on these pages; fuel density 6 lb/gal as printed.
• No maximum landing, zero fuel or per-seat limits printed on these pages.
• Typical empty weight is from the sample loading problem (785 lb at 81.79 in, with oil and coolant); Section 7.3 gives an average empty weight of 775 lb. Use the actual Weight and Balance Form for your aircraft.
• Read from the POH by ZuluCheck and checked by a second reading; verify against your own manual.
