Starting in 2004, Far Part 135 Air Taxi, Air Tours, Air Medical, and Commuter use categories w ere added and tabulated separately from other general use categories. Beginning in 2004, commuter activity is excluded from all estimates. 2003 and prior, commuter activity was included in the Air Taxi use category. Table cells that are populated by a small number of aircraft may display relatively high standard errors for the corresponding estimates. Estimates in these types of categories also may vary noticeably from year to year and should be interpreted with caution. Columns may not add to totals due to rounding procedures. Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes.

Estimates in these types of categories also may vary noticeably from year to year and should be interpreted with caution. Columns may not add to totals due to rounding procedures. Beginning in 2005, light-sport was added as an aircraft type. The quality of information used to classify aircraft by type has improved over time, leaving fewer aircraft in otherwise unspecified "other" categories. Beginning with the 2006 survey year, there are too few aircraft in select "other" categories to support reliable statistical estimation. The relatively small number of aircraft that would have been reported in these categories were reassigned to the most frequently occurring aircraft type within the same major group. Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes. Page 1 - 8Table 1.3

Table Notes: 1Excludes Air Medical Services conducted under FAR Part 135. 2Excludes Air Tour and Air Medical FAR Part 135. Definitions of use categories may be found in Appendix B, Figure B.1. Beginning in 2004, Air Medical was split into General Aviation and Part 135. Prior to 2003, Air Medical was reported as a single use category under General Aviation. Starting in 2004, Far Part 135 Air Taxi, Air Tours, Air Medical, and Commuter use categories were added and tabulated separately from other general use categories. Starting in 2000, public use was asked in a separate question because public use is not mutually exclusive from other use categories. Beginning in 2004, commuter activity is excluded from all estimates. 2003 and prior, commuter activity was included in the Air Taxi use category. Columns may not add to totals due to rounding procedures.

Table cells that are populated by a small number of aircraft may display relatively high standard errors for the corresponding estimates. Estimates in these types of categories also may vary noticeably from year to year and should be interpreted with caution. Columns may not add to totals due to rounding procedures. Beginning in 2005, light-sport was added as an aircraft type. The quality of information used to classify aircraft by type has improved over time, leaving fewer aircraft in otherwise unspecified "other" categories. Beginning with the 2006 survey year, there are too few aircraft in select "other" categories to support reliable statistical estimation. The relatively small number of aircraft that would have been reported in these categories were reassigned to the most frequently occurring aircraft type within the same major group. Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes. Page 1 - 14Table 1.6

Table Notes: 1Excludes Air Medical Services conducted under FAR Part 135. 2Excludes Air Tour and Air Medical FAR Part 135. Definitions of use categories may be found in Appendix B, Figure B.1. Beginning in 2004, Air Medical was split into General Aviation and Part 135. Prior to 2003, Air Medical was reported as a single use category under General Aviation. Starting in 2004, Far Part 135 Air Taxi, Air Tours, Air Medical, and Commuter use categories were added and tabulated separately from other general use categories. Starting in 2000, public use was asked in a separate question because public use is not mutually exclusive from other use categories. Beginning in 2004, commuter activity is excluded from all estimates. 2003 and prior, commuter activity was included in the Air Taxi use category.

Columns may not add to totals due to rounding procedures. Beginning in 2007, the survey asked the state in which the aircraft was "primarily flown" rather than where the aircraft was "based." Estimates by state and region may vary from previous years.
