1. A method for comparing flight management computer instructions for an airspace procedure, the method comprising:
receiving a first translation of the airspace procedure, wherein the first translation comprises a first set of instructions for a flight management computer based on the airspace procedure;
receiving a second translation of the airspace procedure, wherein the second translation comprises a second set of instructions for a flight management computer based on the airspace procedure;
simulating the first translation on a computer-based simulator configured to simulate a response of an aircraft operating with a flight management computer operating on the first set of instructions of the first translation, wherein simulating the first translation comprises generating a first trajectory file, and wherein the first trajectory file includes a plurality of data points associated with one or more attributes of the simulated response;
simulating the second translation on the computer-based simulator configured to simulate a response of an aircraft operating with a flight management computer operating on the second set of instructions of the second translation, wherein simulating the second translation comprises generating a second trajectory file, and wherein the second trajectory file includes a plurality of data points associated with one or more attributes of the simulated response;
for each data point of the plurality of data points of the first trajectory file, determining a closest data point from the plurality of data points of the second trajectory file;
determining which data points of the plurality of data points of the second trajectory file were not determined to be the closest data point with a data point of the plurality of data points of the first trajectory file;
for each data point of the plurality of data points of the second trajectory file not determined to be the closest data point with a data point of the plurality of data points of the first trajectory file, determining a closest data point from the plurality of data points of the first trajectory file; and
for each of the data points of the first and second trajectory files, generating one or more comparison metrics, wherein generating one or more comparison metrics comprises comparing the one or more attributes associated with the closest data points from the first and second trajectory files.
