It could be either homogenous or composed of different types of aircraft. |

The smallest administrative unit of aviation personnel (as opposed to operational/tactical formations of aircraft) |
OPERATIONAL/TACTICAL FORMATIONS
Hikōkitai: |
A carrier aircraft echelon that took the name of the carrier on which it was embarked (and that was as much a part of the carrier’s complement as any of the crew) or the flight echelon of a land-based kōkūtai that took the name of the air base on which it was located |
Daitai: |
Eighteen to twenty-seven aircraft |
Chūtai: |
Nine aircraft |

AVIATION PERSONNEL
Fukuchō: |
Executive officer; second in command of a ship or an air group |
Hikōchō: |
Air officer in charge of flight operations on a carrier or with a land-based kōkūtai. His was essentially a desk position, and he did not normally fly with his unit in combat. |
Hikō buntaichō: |
Sometimes called a buntaichō. Leader of a chūtai of around nine aircraft. Though buntai really has no appropriate English translation, for lack of any other accurate English term buntaichō has sometimes been translated as “division leader.” |
Hikōtaichō: |
Air group leader; the senior officer of an air group in combat |
Seibichō: |
Maintenance officer of either a land-based kōkūtai or a carrier-based hikōkitai |
Shirei: |
Commander of a kōkūtai; the equivalent of the kanchō (captain) of a ship. Usually an aviator of some experience. As a rule he did not fly with the air group in combat. |
