How to use this calculator
- Enter load factor. Use the g load you want to convert.
- Enter stall speed. Use the relevant 1g stall speed for the accelerated-stall output.
- Read bank angle. The angle is the equivalent coordinated level-turn bank.
- Check stall speed. Review the accelerated stall speed at that load factor.
How it works
The bank relation is bank = acos(1 / n). The stall relation is Vs_n = Vs x sqrt(n).
Pair it with load factor from bank, accelerated stall and turn load factor.
Worked example
Verified against the live calculator
A 2 g coordinated level turn corresponds to acos(1 / 2) = 60 degrees of bank.
Frequently asked questions
How do you convert load factor to bank angle?
For a coordinated level turn, bank angle = acos(1 / n).
Is this valid for all maneuvers?
No. It only gives the equivalent coordinated level-turn bank angle for the entered load factor.
How is stall speed included?
The calculator also applies Vs_n = Vs x sqrt(n).
Why use this instead of the bank-angle calculator?
This page starts from a known or target g load and finds the equivalent bank context.
Method & assumptions
- Assumes coordinated level-turn geometry for the bank-angle result.
- Does not model slips, skids, vertical acceleration transients, turbulence or aircraft-specific limits.
