According to an aspect, a method of monitoring landing of an aircraft includes determining whether the aircraft is in a landing phase to maneuver the aircraft to a landing zone. Either or both of a landing profile monitor and a pattern matcher can set a landing instability indicator. The landing profile monitor compares aircraft sensor data indicative of a current state of the aircraft to a landing profile of the aircraft and sets the landing instability indicator based on the landing profile. The pattern matcher identifies a pattern associated with the landing zone in perception sensor data indicative of current conditions at the landing zone, monitors the pattern for a change indicative of landing zone instability, and sets the landing instability indicator based on detecting the change indicative of landing zone instability. Landing abort logic is triggered to abort landing based on determining that the landing instability indicator is set.
