Air carrier is defined as aircraft with seating capacity of more than 60 seats or a maximum payload capacity of more than 18,000 pounds, carrying passengers or cargo for hire or compensation. Air Taxi is defined as aircraft designed to have a maximum seating capacity of 60 seats or less or a maximum payload capacity of 18,000 pounds or less, carrying passengers or cargo for hire or compensation. General aviation is defined as takeoffs and landings of all civil aircraft, except for air carriers or air taxis. Military is defined as operations by all classes of military takeoffs and landings at FAA and FTC facilities. Note that the definitions of air carrier and air taxi are not the same as those used for air carrier and operator certification in Part 121 Operating Requirement: Domestic, Flag and Supplemental Operations and Part 135 Operating Requirements: Commuter and On Demand Operations and Rules Governing Persons on Board Such Aircraft. Local Operations include \"operations by civil and military aviation remaining in the local traffic pattern, simulated instrument approaches at the airport, including the following subcategories, and operations to or from the airport and a practice area within a 20−mile radius of the tower. \n1. Civil: All civilian operations, including local flights by air carrier and air taxi aircraft. \n2.
