For this reason estimates reported for 'other' categories may varygreatly from year to year and should be evaluated with caution.Columns may not add to totals due to rounding procedures.Beginning in 2005, light-sport was added as an aircraft type.Page 3 - 6Table 3.2AIRCRAFT TYPETotalPer-Busi-Cor- Instruc-Aerial Aerial Aerial External Other Sight Air Other Air Air Airsonalnessporate tionalApps Obs Other Load Work SeeMed1Taxi2Tours MedFixed WingFixed Wing - Piston1 Eng: 1-3 SeatsEst.
