FIELD: instrument engineering.
SUBSTANCE: invention refers to instrument engineering and can be applied in aircraft (AC) safety systems. The preset effect is enabled by that said device (1) comprises first threshold evaluator (3). The threshold value depends at least on flight path and current navigation errors. Second evaluator (4) performs present and actual altimetry. Third evaluator (5) compares said present actual altitude to the threshold value. Fourth evaluator (8) generates an emergency alert if the present actual altitude goes down to or drops below the threshold value. Fifth evaluator (10) controls an AC when the present actual altitude goes down to or drops below the threshold value.
EFFECT: enhancement.
