Table Notes:
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.
Beginning in 2005, light-sport was added as an aircraft type.
The wording and format of survey questions about flight plans and flight conditions was changed in 2007. Estimates may vary from previous years.
Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes.

Table Notes:

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 2005, light-sport was added as an aircraft type.
The wording and format of survey questions about flight plans and flight conditions was changed in 2007. Estimates may vary from previous years.
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.

Table Notes:

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.
Note that the flight plan categories are split across pages so that more detail can be reported.
Beginning in 2005, light-sport was added as an aircraft type.
Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes.
The wording and format of survey questions about flight plans and flight conditions was changed in 2007. Estimates may vary from previous years.

Table Notes:
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.
Note that the flight plan categories are split across pages so that more detail can be reported.
Beginning in 2005, light-sport was added as an aircraft type.
Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes.
The wording and format of survey questions about flight plans and flight conditions was changed in 2007. Estimates may vary from previous years.
