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.The small number of aircraft in some of the 'other' categories (e.g., "Piston: Other," "Turbojet: Other") may result in relatively high standard errors for estimates of the number of active aircraft and hours flown. For this reason estimates reported for 'other' categories may vary greatly from year to year and should be evaluated with caution.Columns may not add to totals due to rounding procedures.
