Touch-and-Go
Touch-and-Go is a term used in many ways:
TaG engines are kart engines which have an electric starter motor and so don't have to be pushed like many other varieties. They are usually two-stroke 125cc non-gearbox machines. Mostlast significantly longer than 100cc engines before needing a rebuild, because they do not rev as high (therefore less stress on parts) and so produce the same amount of power with a higher capacity.
Popular engines include the Rotax Max and the Parilla Leopard.
Touch-and-Go is a pilot's term for a manuever that is common when learning to fly an airplane.
It involves landing on a runway and then taking off again without coming to a stop. Usually the pilot then circles the airport and repeats the maneuver. This allows many landings, the most difficult part of flying, to be practiced in a relatively short time.
