Prior to 1990, it was the number of aircraft reported in use during December of a given year.ī Details may not add to totals due to estimation procedures and rounding. Beginning in 1990, the number of aircraft is the monthly average reported in use for the last three months of the year. This definition is more encompassing than that in the Federal Aviation Administration (FAA) Aviation Forecast- jet aircraft, 60 seats or more carrying passengers or cargo for hire. Subcategories data under air carrier are no longer provided by the FAA after 2008.Ī Air carrier aircraft are aircraft carrying passengers or cargo for hire under 14 CFR 121 (large aircraft-more than 30 seats) and 14 CFR 135 (small aircraft-30 seats or less). Due to the manual summation of experimental total, the percent standard error cannot be calculated.įrom 1995 to 2009, numbers for active fleet under air carrier may not add to totals due to different sources. In 20, the totals shown for experimental aircraft were manually calculated by summing the figures from amateur, exhibition, experimental light-sport, and other experimental. Prior to 2012, estimates for experimental light-sport aircraft were not included in the experimental category. 2011 data on the table are from FAA's Aviation Forecast estimates.īeginning in 2004, commuter activity is excluded from all estimates. The FAA is engaged in re-calibration efforts. Totals may not agree with those in other tables as revisions to prior year data are reported at the aggregate level only.ĭetails may not add up to totals due to rounding in the source.Įstimates from the 2011 GA Survey are currently not available. Listed engine configurations (e.g., Two-, Three-, Multi-) represent all applicable combinations for each aircraft type. Failure to comply with this requirement leads to revocation of the registration certificate and exclusion of the aircraft from the official count of the following year. Since 1970, annual verification of aircraft registrations is required. As a result, thousands of aircraft that had been destroyed over the years remained in the system. Prior to 1970, aircraft counts included aircraft retained in FAA data systems until the owners requested that they be deregistered.
