Calculate the Cessna 421 Golden Eagle weight, CG and takeoff distance
Your own empty mass (weighing report, optional)
The POH has no standard empty moment for this model – enter the empty mass CG from your weighing report to get the CG.
Leave empty to use the typical POH empty mass. Your aircraft's weighing report is what counts.
Calculated on the BriefingPal server from the POH data. Nothing is stored, no cookie. Planning aid only – the POH/AFM and your weighing report are authoritative.
Cessna 421 Golden Eagle key figures by model
| Model | Built | MTOW | Empty mass¹ | Usable fuel | Max. baggage | Useful load with full fuel¹ |
|---|---|---|---|---|---|---|
| 421C Golden Eagle | 1981 | 3,379 kg (7,450 lb) | 2,145 kg (4,729 lb) | 206 US gal (780 L) | 45 kg (100 lb) | 674 kg (1,486 lb) |
¹ Typical empty mass from the POH sample loading; your aircraft's current weighing report applies. Useful load = MTOW − empty mass − usable fuel (people, baggage, oil if not included).
Cessna 421 Golden Eagle takeoff and landing distance
BriefingPal result at MTOW, sea level, 15 °C, no wind, dry paved runway, normal takeoff and landing per POH with the app's default flap setting, without safety factor:
| Model | Takeoff ground roll | Takeoff over 50 ft | Landing over 50 ft | Landing ground roll |
|---|---|---|---|---|
| 421C Golden Eagle | 550 m (1,800 ft) | 710 m (2,340 ft) | 715 m (2,350 ft) | 235 m (780 ft) |
Hot and high: at 5,000 ft and 25 °C (density altitude about 7,300 ft) the 421C Golden Eagle needs about 1,140 m (3,740 ft) to clear 50 ft – 60 % more than at sea level. Calculate density altitude →
In BriefingPal you enter your actual weight, airfield, temperature and wind. The app reads the POH charts for these conditions, compares the result with TORA/LDA of the selected runway and can add a 1.15 safety factor.
Cessna 421 Golden Eagle climb and cruise performance
| Model | Rate of climb at sea level | Time / fuel to 6,500 ft | Cruise TAS at 6,500 ft | Fuel flow |
|---|---|---|---|---|
| 421C Golden Eagle | 1,930 fpm | 4 min / 2.7 US gal | 188 kt | 38.0 US gal/h (144 L/h) |
MTOW, ISA, default power setting of the POH cruise table. Values change with weight, temperature and the power you choose in the app.

How to calculate Cessna 421 Golden Eagle weight and balance
- Choose the Cessna 421 Golden EagleType the registration or pick Cessna → Cessna 421 Golden Eagle → your model. Stored weighing data of the registration are used automatically.
- Enter people, baggage and fuelWeights in kg or lb, fuel in US gallons or litres. MTOW and every station limit are checked instantly.
- Check the CG envelopeTakeoff, zero-fuel and landing points are drawn into the Cessna 421 Golden Eagle envelope from the POH.
- Add airfields and routeTakeoff and landing distances, climb, cruise and fuel follow from the same weight – then print the briefing PDF.
