What name is given to Leonardo da Vinci's flying invention in Assassin's Creed II?

Leonardo da Vinci's flying invention in Assassin's Creed II is called the Flying Machine.

In the game, Leonardo builds a glider inspired by his studies of birds and gives it to Ezio Auditore for a mission over Renaissance Venice. Ezio uses the machine to reach the Palazzo Ducale, launching from rooftops and gaining height from fires placed beneath the glider.

The sequence is fictionalized, but it draws on Leonardo’s real notebooks, which contain extensive observations of bird flight and sketches for ornithopters and other flying devices. Leonardo did not successfully fly such a machine in historical reality, and the game’s working glider is an imaginative interpretation of his designs.

The Flying Machine is distinct from the Codex pages, which Leonardo deciphers and translates for Ezio. It is also not a permanent vehicle system; it appears as part of a specific story mission in Assassin's Creed II.
