As the name suggests, this vimana (plane) is like a bird. It is supposed to contain the following parts: Peetha (floor board), hollow mast, three wheeled keelakas (hinges) with holes, four heaters, air suction pipes, water jacket, oil tank,shakuna yantra, two wings, tail portion to enable the vimana to fly, owshyamaka yantra or heat engine, etc.

It has several tiers, each one containing different yantras (machines). The drawings show parts like cylinder, piston worm gear, and pumps which seem entirely modern (beyond 18th century).
Principles – A few lines have been devoted to the function of wings and tail and they appear to be incorrect.

From what is given in the following verses:

It appears that great importance is given to the tail portion for the generation of lift. Also the function of the hinge wings becomes unclear in this context. It may be noted that it is the wings which should contribute to the life of the craft and the tail portion to its controllability.
