Probability of exceedance | 10^{−7}/moment | 10^{−8}/moment |

Protection level (PL)^{*} | ^{5σ}_{position} | ^{6σ}_{position} |

Lateral alert limit | 0.5 m | 0.3 m |

Longitudinal alert limit | 0.5 m | 0.3 m |

Lateral maximum allowable position error standard deviation | 0.1 m | 0.05 m |

Longitudinal maximum allowable position error standard deviation | 0.1 m | 0.05 m |

*PL*=*K*_{ffmd}*σ*_{position}, where*K*_{ffmd}is the fault-free missed detection multiplier calculated from the probability of exceedance and cumulative distribution Gaussian function (SC-159, 2004).
