– are allocated to the engine manufacturing sector. In a similar fashion, avionics are allocated to the Radio and TV Communications sector. Each aircraft type has a unique share of airframe costs, engines, avionics, and interior. Thus, the generalized I/O for aircraft is made specific to individual aircraft types.
As the example below (Table 7) shows – based on approximate shares for an aircraft within the GA category – this allows a finer detailed split of effects on sales. This “hybrid” aircraft represents the average distribution in the main categories of expenditure on a new aircraft. The column on the far right is the new I/O category produced using these splits. The column then shows the approximate direct spend by industries for each dollar of sales of a hybrid aircraft.

Thus, for a dollar of direct purchases of a GA aircraft, it is expected that, in addition to the value generated by the aircraft itself, they will buy about 4.4 cents from other aircraft integrators and parts manufactures. Aircraft engine manufacturers’ main suppliers are other companies in the engines and turbines category, which make the parts that go into aircraft engines (these two sectors are virtually the same companies). Approximately 26 cents of each dollar will contribute to GDP in the form of value-added. The lion’s share of this, or nearly 22 cents, will be in the form of wages.
However, once all the direct and indirect flows that are associated with making an aircraft are taken into account (Table 8), the full impact of that dollar of sales can be observed. Thus, for every dollar of sales of general aviation aircraft, one can expect $2.51 in direct and indirect benefits to the economy. This excludes the impact that comes from the wages and salaries of the workers in the industries affected. They spend their money throughout the economy. Table 9 indicates the distribution of private consumption expenditures of these workers and the industries mainly impacted directly. Each of these industries then buys from other industries producing a multiplier on wages of slightly more than two times the wages and salaries.
