Systems and methods for handling ARAIM terrain database induced errors are described herein. In certain embodiments, a method includes computing position information from a global navigation satellite system. The method further includes computing altitude based on retrieved information from a vertical position sensor and a terrain database. Additionally, the method includes computing a horizontal protection level associated with the position information. Also, the method includes estimating an error for a terrain database based on the altitude, position information, and the horizontal protection level. Moreover, the method includes calculating a new protection level based on the position information and the altitude accounting for the estimated error for the terrain database.
