info_node_air is a point entity available in all GoldSrc games.

Note:This entity is not very well suited for helicopters
For helicopters like the monster_apache and the monster_osprey, it's better to use path_corner instead of info_node_air entities.

Note:monster_apache will work with info_node_air but will have difficulties finding it's enemy and will wobble weirdly.
For the monster_osprey, the game/mod will crash because it expects path_corner entities and not info_node_air ones.

info_node_air has the same responsibility as info_node. The main difference is that this one is designed for flying monsters. It is also designed for aquatic monsters.

From the console, you can use the impulse 195 command to see a glowing path of node tracks for flying monsters. This will show up any weak points in your placement and areas that may need more nodes.
