SUITABLE AERODROMES — ASSESSMENT — PREVIOUS OPERATIONAL DATA — TERMINOLOGY: MAKE, MODEL, SERIES AND VARIANT
The following terms, in accordance with the ICAO Commercial Aviation Safety Team (CAST) taxonomy, are often used (e.g. AMC1Â SPA.LVO.110):
(a) Aircraft make: The aircraft make is the name assigned to the aircraft by the aircraft manufacturer when each aircraft was produced. In most cases, the aircraft make is the common name of the aircraft manufacturer; for example, Airbus, Boeing, Embraer, etc.
(b) Aircraft model: An aircraft model is an aircraft manufacturer’s designation for an aircraft grouping with a similar design or style of structure. In EASA type certificate data sheet (TCDS), this means the aircraft type certificate; for example, A330, B777.
(c) Aircraft series: An aircraft series is an aircraft manufacturer’s designation to identify differences within an aircraft model grouping. It provides a further specification to the aircraft type; for example, B777-232 where the series is the number 232. Some manufacturers define the so-called master series: An aircraft master series creates a grouping of similar aircraft series for analytical purposes and to identify aircraft series that share airworthiness properties. A master series contains aircraft series from within one aircraft model. For example, A320-100 and A320‑200: the A320-100 master series only has one series (A320-111), while the A320-200 master series has many series (211, 212, 214, 215, 216, 231, 232, 233).
(d) Aircraft variant: a variant defines different sets of limiting structural masses (e.g. MTOW, MLW, MZFW, etc.) within a series. For example, A320-232-007 or the A330-243 RR engine’s variant 052. Variants are not covered in the ICAO Cast taxonomy; however, they may be specified in the EASA TCDS.
