Taxiing, also sometimes written "taxying", is the movement of an aircraft on the ground, under its own power, in contrast to towing or push-back where the aircraft is moved by a tug. The aircraft usually moves on wheels, but the term also includes aircraft with skis or floats (for water-based travel).
An airplane uses taxiways to taxi from one place on an airport to another; for example, when moving from a terminal to the runway. The term "taxiing" is not used for the accelerating run along a runway prior to takeoff, or the decelerating run immediately after landing.
The Saab 105 is an aircraft developed in the early sixties as a private venture by Saab for the Swedish Air Force. It is a high-wing, twin engine trainer aircraft. The Swedish Air Force designation is SK 60. It first entered service in 1967 to replace the De Havilland Vampire.
Originally, it featured two Turbomeca Aubisque low bypass turbofan engines, licence-manufactured by Volvo Flygmotor as the RM 9. An updated version is equipped with the Williams International FJ44, designated RM 15.
A total number of 150 aircraft were bought by the Swedish Air Force, and another 40 were exported to Austria, designated Saab 105 OE.
The Saab 105 is also the aircraft used by Swedish Air Force display team Team 60 and was used by the Austrian Air Force display teams "Karo As" and "Silver Birds".
