Which category is A321-271NX in?

Question

So I was wondering what is the Aircraft categories all about because from my previous questions answer I got to know about something called Cat D type aircraft so it made me curious to know what are the different types of aircraft categories and which one is the A321-271NX because it happens to be special for me !

Answer 1

The code is for the exact variant for this Airbus:

• A321: This is an Airbus A321, the longest variant of the A320 family.

• 27*: It comes with PW1100 engines (which makes it a neo).

• 271: The exact engine variant, which can be found in the TCDS (Type Certificate Data Sheet):

  PW1133G-JM Geared Turbo Fan jet engines (MOD 161002)

• N: Added for all neo variants.

• X: This means the aircraft has Cabin Flex, which allows the operator more freedom in choosing emergency exits:

  these doors’ configuration flexibility are there to enable all customers’ operational needs without compromising on cabin comfort

The "Cat D" you mentioned is the approach speed categorisation:

Category	Approach Speed
A	< 91 kt
B	91-120 kt
C	121-140 kt
D	141-165 kt
E	166-210 kt

The Airbus A321 can be in approach category C or D, depending on the maximum landing weight:

A321 has Approach Category C to 75.5 tonnes MLW and D beyond that to 77.8 tonnes.

You can find the maximum landing weights for the A321neo in the Airbus Aircraft Characteristics Document:

All maximum landing weights for the A321neo are above 75.5t, which would make them all Cat D.
