Maiden flight
In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown.The maiden flight of a new type is almost invariably flown by a highly experienced test pilot.Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness.In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter operation.An incomplete list of maiden flights of notable aircraft types, organized by date, follows.
