The integrated altitude solution may compensate for vertical speed offset. The system may provide secondary altitude monitoring by comparing radar altimeter data to local object data to verify obstacle clearance height. The system may include a lateral monitor for validating GPS lateral position data based on weighting and limiting of altitude sources controlled by a height above threshold estimate from the vertical monitor. Validity information may be presented to the pilot or autopilot.
