Grob G-120

Grob G-120

The Grob G 120A is a two seated training and aerobatic low-wing aircraft with a corrosion-free carbon composite airframe. 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 cross empennage.

The first buyer was Lufthansa Flight Training.


The airframe made of carbon fibre reinforced plastic is totally corrosion free and provides the maintenance accessibility of the built-in parts. It enables the aircraft to stand the aerobatic program up to +6/-4g. Its minimum service life is just over 15,000 flight hours.

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. A second thrust lever is available.
