Here’s a comprehensive table summarizing the key weight and balance information for various Bell helicopter models:
| Model | Empty Weight (lbs) | Max Gross Weight (Internal) (lbs) | Max Gross Weight (External) (lbs) | Useful Load (Internal) (lbs) | Max External Load (lbs) |
|---|---|---|---|---|---|
| Bell 429 | 4,465 | 7,000 / 7,500* | 8,000 | 2,535 / 3,014* | 3,000 |
| Bell 412EPI | 6,815 | 12,200 | 13,000 | 5,385 | 5,000 |
| Bell 212 | 8,400 | 11,200 | 11,200 | 2,800 | Not specified |
*The higher values for the Bell 429 represent increased gross weight configurations where approved.
Additional Information:
Bell 429:
- Empty weight may vary slightly (4,465 – 4,486 lbs) depending on configuration3.
- Minimum empty weight for SPIFR (Single Pilot IFR) configuration: 4,222 – 4,245 lbs3.
Bell 412EPI:
Bell 212:
- Maximum gross weight is 11,200 lbs for both internal and external operations1.
- Weight-altitude-temperature (WAT) limitations apply and may restrict maximum takeoff weight in certain conditions5.
General Considerations:
- Always consult the specific aircraft’s Pilot’s Operating Handbook (POH) or Rotorcraft Flight Manual (RFM) for exact weight and balance limitations345.
- Center of gravity (CG) limits vary based on gross weight and must be calculated for each flight5.
- Factors such as altitude, temperature, and mission requirements can affect the actual useful load and performance capabilities15.
This table provides a quick reference for Bell helicopter weight and balance information. However, it’s crucial to use the specific aircraft’s documentation and current weight and balance data for accurate flight planning and operations.
