3.0  GA’s Direct Contribution
3.01 Direct Contribution Defined
For purposes of this report, the direct contribution of GA is the U.S. economic output created by the manufacture, operation, and maintenance of GA aircraft. Direct contribution measures include the value of new GA aircraft sales, fuel purchases, airport charges (landing and parking), spare parts, and other direct expenditures related to the operation of GA aircraft. As discussed earlier, there are other contributions which are not measured, as well as intangible benefits which may or may not be quantifiable.
The sum total of all purchasing, maintenance, and operating expenditures represent the direct contribution of General Aviation.

Contributions Quantified and Not Quantified

3.02 Direct Contributions Quantified
Using industry sources, federal data, and proprietary data from aircraft manufacturers and service providers, MergeGlobal measured the direct expenditures on General Aviation at the national and state levels. Some of the variables considered are:
3.02.1  New Aircraft Sales – The manufacture of a new aircraft requires not only parts for the airframe, but also the purchase of engines, avionics, interior fitments, tires, brakes, paint, instruments, etc.
3.02.2  Operations and Maintenance – Operators of aircraft have different requirements and their spending patterns can differ greatly. For example, the hangar facilities and crew wages for the operation of a $30 million corporate jet have a much different -and greater -impact than those of a private owner of a single piston engine airplane. Therefore, it is appropriate to attribute spending and usage patterns according to use. MergeGlobal made simplifying assumptions about owner spending, some of which are illustrated in Chart 7 and discussed in section 2.03, Uses of General Aviation Aircraft.
