aircraftGlobalType

The global data hold the top-level aircraft requirements of the model, i.e. the values the design has to reach in range, payload, airport compatibility and flight performance, and the flight envelopes of the aircraft. Each requirement gives the required value and the value the design actually reaches (requirementType).

The example shows some of the requirements of a short-range airliner. Its flight envelope is shown in flightEnvelopeType.
