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.
Estimated number of light-sport aircraft has increased significantly in 2007 due to mandatory regulation process changes.
Columns may not add to totals due to rounding procedures.
