This is my first post on this forum and wasn't sure where to ask this query. Apologies in advance if this isn't the right place to ask the question.

I understand the differnce between different variants of an aircraft like 737-700 and 737-800. However, I am unable to understand how a 737-85R is different from say 737-8HX. I tried to search for answer a lot albeit unsuccessfuly.

Anybody who can explain?

Cheers

Those are the customer codes of Boeing for the various Airlines and leasing companies, like 5R is the customer code for Jet Airways, 37 for Air India etc
Hence 737-85R or 777-337 ER

Whenever Boeing sells an aircraft, they replace the last two numbers of the model number, such as B737-800, with the customer code that Boeing assigns to every carrier it sells it's aircraft..

For example, whenever Jet Airways gets an aircraft from Boeing, they get it as B737-85R, where 5R is the Boeing customer code...

Sometimes, due to financial constraints, the airlines leases the aircraft, then Boeung assigns the lessors customer code, who then passes it on to the airline..For example Jet owns certain aircraft that are leased from certain banks, hence you see 737-8HX or 737-8AL...

Customer configuration determines the last two digits.......All types need not be similiar......they can have customer chosen variables.

Likewise, in Airbus, the naming convention goes like this:

Airbus A340-541

A = Airbus
340 = Type
-5 = A340 Model Variant
4 = Engine Code
1 = Version Code

Engine codes
Code Manufacturing company
0 General Electric
1 CFM International
2 Pratt & Whitney
3 International Aero Engines
4 Rolls-Royce
6 Engine Alliance
