Here is a ground training complex for aircrafts located in the Crimea. It was built at the end of the 70s specially for an aircraft carrier “Admiral Kuznetsov”. The complex is about to be modernized to look like a deck of a modern aircraft carrier.
The simulator named “Nitka” helps pilots to practice the technique of taking off and landing on a deck to feel more confident in the sea. The complex can even imitate different weather conditions, rolling, for example. You do not see this but “Nitka” is a big structure whose equipment is mostly hidden under the ground (including its hydraulic braking system).
