The forward movement of an aircraft, usually with engines off using the power of a specialized ground vehicle attached to or supporting the nose landing gear. It may occur for in service and out of service aircraft and this will affect the promulgation of procedures and the required qualification for those occupying the flight crew seats on the aircraft during the manoeuvre. As part of out of service re positioning of aircraft supervised by maintenance personnel, it may follow 'ushback' from a nose-in gate of an empty aircraft with engines off.
Gliders are planes without an engine and in order to bring them up to altitude they must be towed by a powered aircraft which pulls the glider along by a cable. When they reach the predetermined altitude the glider releases the cable and off it goes.
5 mph
Aircraft towing speeds depend on the operating airline or airforce, but are usually around 4 - 5 mph.
Usually walking speed, -4-5 mph.
Aircraft line operations refers to all of the various services performed on aircraft. This includes fueling, towing, deicing, loading & unloading and other services aircraft need between flights.
Atowing gate in aviation is a boarding and deboarding station of an airport's apron in which the aircraft cannot park in or depart from without the assistance of an aircraft tug. Aircraft tugging requires a grater amount of time than the aircraft parking itself since the aircraft tug is not nearly as strong as the aircraft engines.
Vehicles towing aircraft only
You should never tow an aircraft faster than a fast walking pace or slow jog. Somewhere around 3 or 4 mph. Some aircraft can be very unstable when being towed (afterall they are essentially just big, top-heavy tricycles) so special care should be taken when going around turns, over large bumps, or on slopes when towing an aircraft.
That figure will vary from 25 to 100 feet. The figure depends on the operator or the airfield control.
That is when 2 aircraft narrowly miss each other in flight.
A vehicle that is properly set up for towing. Meaning it has the towing capability for the trailer one intends on towing as well as electric brake and light hook-ups.
Remotely piloted aircraft
A 'hangar' is a place to house aircraft and work on them.
