The Grob G 120 is a two-seat training and aerobatic low-wing aircraft with a carbon composite airframe, built by Grob Aircraft. It is based on the Grob G 115TA training aircraft and is specially designed for military and civil pilots training. It has a tricycle landing gear and a low tailplane.
Design and development
The airframe is made of carbon fibre reinforced plastic and is stressed to +6/-4g. Its minimum service life is just over 15,000 flight hours.[1]
The cockpit provides room for students wearing military equipment and helmets. The plane is equipped with movable seats and rudder pedals and an air conditioning system.[citation needed] A second thrust lever is available.[1]
