##TPA and TPA Breakpoint ##TPA and TPA Breakpoint
TPA stands for Throttle PID Attenuation and according to [AlexYork.net](http://blog.alexyorke.net/what-is-tpa/):
> "TPA basically allows an aggressively tuned multi-rotor (one that feels very locked in) to reduce its PID gains when throttle is applied beyond the TPA threshold/breakpoint in order to eliminate fast oscillations.."
Note that TPA is set via CLI or on the PID TUNING tab of the GUI. tpa_breakpoint is set via CLI Note that TPA is set via CLI or on the PID TUNING tab of the GUI. tpa_breakpoint is set via CLI
Also note that TPA and tpa_breakpoint may not be used in certain PID Contorllers. Check the description on the individual controller. Also note that TPA and tpa_breakpoint may not be used in certain PID Controllers. Check the description on the individual controller.
TPA applies a PID value reduction in relation to full Throttle. It is used to apply dampening of PID values as full throttle is reached. TPA applies a PID value reduction in relation to full Throttle. It is used to apply dampening of PID values as full throttle is reached.
