1. A method comprising:
determining, at a computing system of an aircraft, a target path for an approach to landing based on flight plan data;
determining, at the computing system based on real-time aircraft data, an approach phase of a plurality of approach phases for the approach to landing;
determining, at the computing system, a real-time operational region of the aircraft for each monitored condition of monitored conditions for the approach phase based on the real-time aircraft data, the target path, and operational regions for each monitored condition, wherein the operational regions for a particular monitored condition of the monitored conditions for the approach phase include a target region defined by one or more first thresholds, a first end region defined by a second threshold, and at least one intermediate region between the target region and the first end region;
accessing, at the computing system, notification content for each particular monitored condition for the approach phase, wherein the real-time operational region for the particular monitored condition for the approach phase is outside of the target region of the particular monitored condition for the approach phase, wherein a first real-time operational region for the particular monitored condition corresponds to first particular notification content during a first approach phase, and wherein the first real-time operation region for the particular monitored condition corresponds to second particular notification content during a second approach phase;
sending one or more notification signals based on the notification content from the computing system to one or more output systems; and
automatically initiating, by the computing system, a go-around responsive to the approach phase corresponding to a particular approach phase and a real-time operational region for a first monitored condition being in an end region of one or more end regions for the first monitored condition, and wherein an altitude of the aircraft for the particular approach phase is below a critical altitude.
