Robinson R44 weight & balance

Data source

POH Section 2 pages 2-3 and 2-4 (Weight Limits, Center of Gravity Limits chart); Section 6 pages 6-4 to 6-7 (Loading Instructions, Sample Loading Calculation, Worksheet) (pages 21-22, 78-81 of r44-astro-raven-i__poh__full-book-rev-2024-01-26.pdf) · version type

• Minimum gross weight 1550 lb; maximum gross weight 2400 lb.
• Maximum per seat 300 lb including the baggage compartment under that seat; maximum 50 lb in any baggage compartment (modelled as a group per seat).
• Solo pilot of 150 lb or more with all doors installed ensures CG within limits; lighter pilots must compute W&B and removable ballast may be required (minPilot left null).
• Fuel tank capacities are not on the pages read (they are in Section 2 page 2-7); fuel max/usable left null. Worksheet uses 6 lb/gal.
• A longitudinal arm of 104.5 in may be used for combined main and aux fuel (not for lateral CG).
• Fuel burn moves CG forward; check both takeoff and zero-usable-fuel conditions. Chart shows a dashed line for most forward CG with full fuel to remain within limits at zero fuel.
• Envelope vertices read from the chart: forward limit 92.0 in up to 2200 lb, 93.0 in at 2400 lb; aft limit 102.5 in up to 2000 lb, tapering to about 98.0 in at 2400 lb. Verify against chart.
• Seat arm 49.5 in for front seats: if additional backrest cushion is used, subtract thickness of compressed cushion.
• Door removal (forward 7.5 lb each at 49.4 in, aft 7.0 lb each at 75.4 in) and left seat controls removal (2.0 lb at 31.0 in) must be subtracted when applicable.
• Lateral CG limits also apply (chart page 2-4: roughly ±3 in, reduced aft of station 100); lateral arms given in loading table.
• Read from the POH by ZuluCheck and checked by a second reading; verify against your own manual.
