1. An avionics computer apparatus comprising:
a display device;
a data storage element; and
at least one processor in data communication with the data storage element, the display device, and a memory storing processor executable code for configuring the at least one processor to:
receive an updated flight plan;
retrieve a set of predefined rules from the data storage element;
apply each of the set of predefined rules to the updated flight plan before the flight plan is accepted; and
render the updated flight plan on the display device,
wherein:
the predefined rules comprise;
a new destination, where the updated flight plan including a new destination is a violation;
a minimum altitude defined by terrain features proximal to segments of the updated flight plan; and
a definition of continuous progressive altitude changes up to a cruising altitude and down to a landing altitude, the definition including a violation if a sequence includes a descent, then a climb, then another descent; and
any violations of the predefined rules are rendered in a visually distinct style.
