The question is about the initials put on aircraft. I know ER and LR .. etc but gumfed when it comes to the following so could someone help me out.

Looking for what the ...

M (Boeing 747-400M - KLM operate a lot of them)
SCD (Attached to a lot of freighters)

These are combi aircraft. (Both cargo and passengers on the main deck)

Does anyone know why 'M'? Why not 747-400C for combi, what does the 'M' stand for?

Hmmm. Main deck cargo door?

I am pretty sure that WestWing is correct as far as "mixed" goes.
The 737-200 combis in AS' fleet are listed as 73Ms in the sked.

'C' was already taken by the 'Convertable' 747 which has a nose cargo door as well as the SCD!

Going back to the 747-200, there were both 'M' and 'C' models. The C stands for convertible - Boeing's idea was that these A/C could be used EITHER as pax OR cargo plane. The -200C also has the Nose Door.

The M stands for mixed - both passengers AND cargo on the same plane. The -200M (or -200BM, actually) has no Nose Door, just the Side Cargo Door.

The C model is not offered on the 744, just the Mixed Version.

On the 707, 727, 732, and AFAIK the 73G there also existed C models but no M models. IMHO, they introduced the M designation on the 747 in order to distinguish between the models with the Nose Door and those without it.
