Frequently asked questions
Symbols and assumptions
- Inputs
- The values entered in the fields above
- • Coordinated constant-altitude turn load factor n=1/cos(bank); stall speed at that load Vs_turn=Vs_1g√n, with identical weight/configuration and bank magnitude<90°.

- • Convert angle units before cosine. This relation assumes a coordinated level turn; bank alone does not set load factor in a descending/unloaded maneuver. Preserve the baseline speed convention and aircraft limits; the result is a stall-speed scaling, not maneuver clearance.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
