Estimate adjusted stall speed using published stall speed, aircraft weight, and bank angle. This free aviation calculator helps pilots better understand how loading and turns affect stall speed.
Enter published stall speed, reference weight, actual weight, and bank angle to estimate an adjusted stall speed.
This calculator is a planning and training aid. Actual stall behavior depends on configuration, aircraft type, CG, load factor, and approved aircraft data.
Stall speed is the minimum airspeed at which an aircraft can maintain controlled flight in a given configuration and loading condition. It is not a fixed number for all situations because weight, load factor, and aircraft configuration all matter.
In a turn, stall speed increases because load factor increases. At higher aircraft weights, stall speed also increases. That is why pilots pay close attention to stall margin during maneuvering and approach operations.
In a banked turn, the aircraft must generate more lift to support its weight, which increases load factor. As load factor rises, stall speed rises.
Yes. A heavier aircraft generally stalls at a higher speed because it must produce more lift.
Yes. Flap setting, landing gear, CG, and aircraft configuration can all affect stall speed. This calculator does not replace approved configuration-specific aircraft data.
No. This calculator is a training and planning aid. Always use the approved speeds and procedures in your POH, AFM, checklist, and flight training guidance.
